× FIELD MANUAL Stay sharp. Stay standing. A break from the siege Arcade: look for the CANTINA sign near the courtyard starting spot. Walk down the stairs and through the tunnel. Explore the bar, watch Siege TV with T, then follow the stairs back up. The stairs stay in combat. A shared seven-minute break begins when you enter the room. Choose “Fight from here” to end the break and defend the cantina; incoming fire and enemies resume. When the allowance runs out, the battle resumes where you stand. After ending the break, the cantina stays in combat for the rest of that battle.
Historical deployment Mexican infantry approached in four assault columns: north, northwest, east and a smaller southern column. The compact ranks, exact spacing, wave sizes and defender counts by post are game interpretations. The intro displays this game’s roster, not a surviving historical muster map.
Find your feet Press 1, 2, 3, 4 or 5 to instantly switch fighting positions: north, west, east, south, and Crockett’s palisade. Press Y to return to the courtyard near Isabel and the cantina stairs. Press X or tap Prone to lie down; press it again to get up. You crawl slowly and shoot from ground level. C crouches. Press Z or tap Jump to jump. Space or left mouse fires. Watch the compass: your sector and the direction you face are separate readings. Playing Mexican? Walk up to an outer wall and press F to deploy your ladder and climb. L places it without climbing, or recovers it from the base. Gold marks your ladder on the map; F also climbs army ladders. Texans turn toward threats and move to fill gaps in the line.
Every round counts. Your loaded rounds and spares are: Barrett 10 + 20 rounds, carbine 30 + 180, SAW 200 + 400. Half a magazine still counts. Reloads keep the rounds you have left. Find a wooden ammo chest with green metal boxes on top, press G, and stay nearby for three seconds to refill every weapon and its spare ammunition. Any marked ammo chest works for either side, including those outside the walls. Cyan squares on the map mark resupply locations; a pale cyan ring highlights each chest on the ground. Reloads take game-defined time; these carried loads are mission choices, not a universal military issue standard. Every 25 kills earns two whiskey bottles; carry up to six. Get behind cover and press H for up to 40 health. Isabel offers another bottle every 60 seconds in the courtyard. Liquid courage heals in this game only.
Game statistics & privacy
The opening battlefield tour The flyover shows the actual troops in this game: 52 defenders at the north wall, 50 at the west, 35 at the south wall and gate, 39 in the eastern works, and Crockett with 11 fellow defenders at the palisade. Bowie is in the infirmary. These station counts and individual placements are game interpretations, not surviving historical muster returns. Contemporary accounts describe four Mexican assault columns.
Preparation and queso During the three-minute preparation period, Mexican troops hold their positions. Cross halfway from your starting point toward them and they open fire; the assault countdown continues. The Queso Thrower sprays hot cheese up to 20 metres. Keep the narrower stream on target for sustained damage. It does not set soldiers on fire.
Your unfair advantage The M4A1 has 30-round magazines and a 1–6× TANGO6T-style optic. B selects single or automatic fire. Select the M4 variant in the loadout for single or three-round burst fire. The M249 carries 200-round belts and a 3.4× M145-style optic. The Barrett M107 has 10-round magazines and a 4.5–14× Mark 4-style optic, starting at 14×. V adjusts variable magnification. Reticles, reload animations and damage are game approximations.
Earn your stripes In Arcade, points and direct-fire cash vary by rank. Chevron: NCO. Diamond: commissioned officer. Star: general. Cyan ring: gun crew. Scope a target to see its rank and bounty. Support kills still pay half cash; Mexican-side cash rewards are five times the table to reflect the smaller opposing force.
The infantry rank structure follows the company regulation reconstructed by Alamo de Parras : one captain, one lieutenant, two sub-lieutenants, one first sergeant, three sergeants and eight corporals. Officers occupy leading files; NCOs are spread through the outer and rear files. Those placements are a gameplay interpretation. The 16 enlarged infantry detachments, 64 gunners and 12 mounted staff/escorts share the existing 2,000-person roster; they are not an exact company muster. Musicians are not separately modeled. Duque, Romero and Morales are colonels, while Cos and Castrillón are generals. Santa Anna and Almonte are named at headquarters; the other mounted staff roles are representative.
Crockett’s corner Crockett and eleven other defenders occupy the palisade firing step. The Alamo Trust identifies the palisade as Crockett's believed fighting position ; the exact twelve-man grouping, spacing and firing step are interpretations. The defenders have varied civilian clothing, beards and facial textures. They are not all represented as a uniformed Tennessee company: the Alamo Trust cautions against that popular account .
Take the victory toast now
The default Texan start is in the courtyard, facing the chapel. Click the battlefield, then use WASD to move and Shift to run. In Historical mode, you have 15 seconds to observe and fire before a 55-second artillery barrage. Reinforcements follow at 45-second intervals. Morale must remain below 28% for 18 seconds to break a column; 30% company casualties or 50% officer losses still trigger withdrawal. Some units withdraw under covering fire; routed soldiers run. Four 500-man echelons then advance with 60 ladders. Run through the courtyard, use stores and masonry as cover, and climb the access stairs. Texans hold their posts regardless of casualties, officer losses or attackers on the wall. They turn toward threats and fill nearby gaps. Fallen bodies stay until a new battle begins. The player retains free movement. Press 1–5 to instantly switch between all five defender positions. Gold diamonds mark officers; stars mark generals. Cyan rings mark cannoneers. Mexican batteries occupy separated flanks of the infantry approach. Santa Anna and eleven headquarters staff sit on horses farther behind the northern echelons. Near misses and hits alert the whole headquarters. Mounted survivors immediately gallop toward separate escape lanes and continue retreating while under fire. Every three headquarters staff killed or permanently incapacitated halt the assault for three minutes; 75% senior headquarters losses end the Mexican attack. Light wounds cause scattering but do not count toward the halt. Infantry hold ground and can defend themselves; artillery continues only with a clear firing path. The on-screen halt countdown shows when the assault resumes. Surviving officers, personal bravery, cohesion, and reserves affect whether an assault holds or breaks. The sector display shows morale and the regroup countdown.
Arcade — full assault: Play either side against 2,000 Mexican troops in four overlapping echelons, with 100 ladders. After Isabel’s short welcome and a three-minute preparation countdown, the full assault begins: attackers move faster, climb faster and keep advancing during musket reloads. You can move and fire during the briefing and countdown. Another echelon releases every 40 seconds while reserves remain. Losing 50% of a company’s officers halves its marching speed, including during full assault. Only a company's own 80% killed-or-incapacitated threshold can stop it; officer losses, morale and headquarters casualties cannot halt Arcade assaults or cause neighboring companies to retreat. Texans always hold. The final assault ends once every Mexican company reaches its limit or the defenders and player are defeated.
Both armies start with one M4A1. You play Davy Crockett on the Texan side. Choose your way in; press M during play to see your post and the enemy fronts. Mexican players carry a reusable ladder and start with $1,500. K opens the paused arsenal. Texan-side direct-fire kills pay $100 per private, $175 per corporal, $250 per sergeant with separate bounties for commissioned officers, $2,000 for generals and $10,000 for Santa Anna; Texans also earn $1,200 per echelon repelled. The Elephant Gun Mk II has 12 rounds, faster projectiles and a larger blast; B switches between impact and range-fused airburst. The Queso Thrower projects a narrow stream of hot cheese with reduced damage; G refills its cheese tank at ammunition crates. A-10 support makes an explosive strafing pass, napalm leaves burning ground, and the fictional nuclear strike produces an exaggerated blast, shockwave and mushroom cloud. Support attacks and flame damage spare allies. Buy one use, click its stock button in the side panel, place the target on the overhead map and confirm. The panel always shows F-4, A-10, napalm, truck and nuclear stock, the selected strike and its cooldown. Standard support waits 15 seconds; nuclear support waits 60 seconds. All these effects are invented Arcade game rules, not real weapon-performance models. Historical preserves the original siege, 2,000 attackers and Mexican morale rules.
Operate a cannon: Walk within about 3 metres of a friendly gun on the same platform and press T. Move the mouse to aim, click to fire, and T to leave. Loading is automatic: 16 seconds with surviving crew, 28 when working alone; crew disruption still applies. This player-operated drill is simplified for play.

Position 5 takes you to Crockett’s palisade. Press Y to return to the courtyard near Isabel and the cantina stairs, or tap Y beside the position buttons. The on-screen W/A/S/D buttons also move you while held. Use the Full screen button for a larger view. The minimap starts zoomed into the fort; M switches to the whole battlefield. Carried ammunition is finite; R reloads and G at any nearby marked ammo chest refills the loaded weapons and their spares. Marked chests are beside all four wall firing posts, near the courtyard start, and on the four outside approaches. The M4A1 carries a variable 1–6× optic. B selects single or automatic fire; the M4 variant instead selects single or three-round burst. A burst completes after trigger release; reloading, switching modes or weapons, or pausing cancels pending shots. The Barrett .50 has a 10-round magazine and a variable 4.5–14× scope, starting at 14×. M4 and M249 hits can incapacitate a soldier without killing him. Open Company effectiveness to see unit strength and officer losses; scope a soldier to identify wounds or a replacement officer. The M249 SAW carries a fixed 3.4× M145-style optic: hold right mouse or Alt, or tap Aim. Whiskey restores up to 40 health, capped at 100, after a two-second drink. You start with one bottle and can carry six; every 25 kills earns two bottles, up to that limit. Walk up to the four courtyard stores to collect another bottle; gold squares on the map mark available supplies. Each store has one bottle per battle. Getting hit interrupts drinking, and firing, reloading, switching weapons or pausing cancels it. Whiskey healing is a fictional game mechanic. Red screen edges persist below 50 health, with a seek-cover warning at 50 or less. Hit notices identify the weapon and firing sector; the death report shows the final source and recent damage. Scope distant officers to identify them. Hold right mouse or Alt and move the mouse to aim; you can fire while scoped. The regional tally shows your kills and both armies’ dead/alive soldiers, including officers and crews. Counts follow each soldier’s assigned front, include living reserves and retreating troops, and reset when you deploy again. Click the tally heading to collapse it.
Battle realism & sources Landscape, portrait references & reconstruction notes · Victory ending concept
Mexican companies withdraw after losing half the officers assigned to that attempt or 30% of their attempt strength. Surviving troops regroup for three minutes after reaching shelter or assembly. Existing trained soldiers can become marked replacement officers, using a finite succession pool. Losing half the new officer roster breaks the next attempt too. A company unable to replace at least half its original officer complement becomes permanently combat ineffective. In Historical mode, the Mexican army breaks off the battle at 50% killed or permanently incapacitated, 75% of their initial trained leadership pool lost, or all their companies exhausted. You see an 18-second withdrawal before the result. Texans never withdraw from losses; they hold until killed or incapacitated. These are alternate-history game rules. Nonfatal hits interrupt NPC actions for 2–12 seconds, then leave slower movement, slower reloads and poorer accuracy. At 35 health or less, a survivor remains alive but cannot fight again that battle. Wounded gun crews also work more slowly. The regional Alive count includes incapacitated troops; the top Fit counts exclude them. Arcade Assault Fit also excludes withdrawn companies, staff and crews. Victory requires all 16 assault companies to lose at least 80% of their strength; living staff, crews and retired companies do not block it. Mounted Arcade staff disperse inside the northern battlefield and remain within long-range reach. In Arcade, 3 of 12 headquarters staff killed or incapacitated reduces Mexican infantry marching to 75% speed; 6 reduces it to 50%. This stacks with company officer losses. It does not delay the wave clock or automatically break companies. The Barrett M107 costs $3,000 and offers 14× precision and one-hit torso kills under the game damage rules. Arcade additions use fictional balance values: the M1014 has an eight-shell load and eight pellets per shot, with substantial distance falloff. The MP5 favors close range, the M14 precision, and the M60 sustained heavy fire. Head, torso and lower-body hits have different effects; this is a simplified wound model, not measured medical or ballistic data.
Expanded siege mode fields 2,000 Mexican soldiers against 189 defenders. It has four 500-man echelons, 60 ladders, 8 Mexican artillery pieces, 18 Texan cannon, and twelve mounted headquarters staff. The 2,000-man roster, 60 ladders, opening barrage, access stairs, and headquarters arrangement are alternate-history game settings. The Alamo Trust records 18 serviceable defender cannon. Eight Mexican pieces follow Gregg Dimmick’s reading of Filisola; the inventory is a reconstruction, and individual gun placements are interpreted. Mexican pieces have eight crew (five at the gun, three handling supplies); Texan guns have five. These crew allocations are gameplay assumptions, not a surviving Alamo muster. The cited historical account estimates about 1,800 men in the final assault. All soldiers remain individually targetable, including reserves and cannon crews.
NPC weapon Reload Behavior Flintlock musket 22–32 sec Single shot; accuracy declines sharply with distance. Long rifle 40–60 sec Slower loading; better distant accuracy. Cannon 26–42 sec loading + 4–7 sec aiming with full crew Reduced crews work more slowly; fewer than two silence the gun.
NPCs retain period single-shot firearms. Most assault infantry keep advancing; designated shooters stop to aim and reload. The final approach becomes a short run, with slower ladder carriers. Each column withdraws at 30% casualties in its current assault, 50% officer losses in that assault, or morale below 35% for twelve seconds. Survivors return to their assembly positions and regroup for three minutes. Reserves wait while their column withdraws or regroups. A renewed attack uses surviving soldiers and available reserves; dead soldiers do not respawn. Loss percentages restart for the renewed assault, while the regional dead/alive totals persist. Columns with fewer than twelve available assault troops withdraw permanently after all reserves are released. Texan defenders gain better accuracy from stationary, fully aimed shots, especially with long rifles. Movement, smoke and wounds still reduce accuracy; their 40–60-second rifle reloads remain. NPCs settle their aim before firing. Moving fire is much less accurate; reloading prevents another shot. These timing ranges, hit probabilities, morale thresholds, and the effect of losing commanders are simulation assumptions, informed by period weapon limitations. They are not measured Alamo statistics.
Before firing, both armies’ cannon check the shot path for living friendly troops and hold fire if someone crosses it. A high howitzer arc may clear troops below it. The cannon barrage has delayed impacts, powder smoke, dangerous close hits and debris. Gunners need a clear view before targeting you personally. Going below the wall prevents new personal targeting when the wall blocks that view. Guns lock an observed aiming point for 4–7 seconds, so hidden movement never updates it; shells already fired can still arrive. Most fire is aimed at visible defenders or known fort areas. Dispersion grows with range, and standing still does not give the gun a precision bonus. Crew casualties immediately interrupt loading and cancel aiming. Two of the three modeled crew load and aim at two-thirds speed with worse dispersion; one survivor cannot operate the gun. Scope a cannoneer to see crew count and loading, aiming, interrupted or silenced status. A hit can also disrupt the drill. Field-gun and howitzer effects remain simplified game ballistics: nearby impacts use damage falloff and cover checks, without a full solid-shot, fragment or wall-destruction model. These crew rules and dispersion values are gameplay calibration, not measured 1836 firing-trial data. Santa Anna and the column commanders are identifiable game representations. Their exact positions, portraits, and responses to being shot are fictional. The mounted staff roles are representative rather than an authenticated staff roster. Staff and horses move together during dispersal; the horse mesh does not yet have an articulated walking animation. The opening watch gives you the opportunity to change the historical outcome. The final attack began before dawn. After preparation, ten gameplay minutes cover approximately ninety historical minutes. Dawn follows the calculated March 6, 1836 sun path at San Antonio: the sun rises just south of due east, with matching westward shadows. The flyover, briefing and pauses hold the clock. Visibility is lifted for play; weather and timing are illustrative.
M opens a paused overhead map with every enemy position and each front’s strength. Click a support button, or use 6–9 / 0, to plan a strike: the battle pauses for five seconds. Click the map and confirm. An invalid target, cancellation or timeout spends nothing. The mortar replaces the Browning: six shells per load, 25–650 m range, and actual impact crosses on both maps. Monster truck runs cost $25,000. Choose a drop-off and drive for 30 seconds: W/S accelerate or reverse, A/D steer, Space brakes, X returns early. Walls and elevated positions offer protection.

Guns, flags & the movie tribute Background music volume Both modes field 2,000 Mexican soldiers, including 64 artillery crew and 12 headquarters staff, against 189 Texans. Arcade has four overlapping waves and 100 ladders; Historical has four echelons and 60 ladders. Historical retains the 15-second watch and 55-second barrage. Arcade opens with the courtyard briefing followed by three minutes to prepare.

Assault formations and timing. The March 5 Mexican orders specify assault columns, scaling ladders and a reserve. Four attack fronts are modeled with straight files and companies behind one another. The 12-file widths, spacing, exact sector totals and reinforcement schedule are game estimates, not a surviving deployment diagram. The game’s four reinforcement groups are not four historical assaults. Joe’s account reports two repulses and success on a third attempt, while acknowledging his limited view after Travis fell. The game allows fire-driven local repulses rather than guaranteeing two retreats. Defenders can inflict casualties and withdraw into the Long Barrack or chapel after a breach, when a clear route exists. Marching speed and reloads are approximations; exact historical kill rates are unknown. The final assault lasted roughly 90 minutes, not the game’s compressed battle.
El Degüello was the no-quarter signal associated with the assault. The opening uses a new three-minute brass-and-drum interpretation, “El Degüello · Dawn March,” generated with ElevenLabs Music.
