Dead Space 2 (Oct 5, 2010 prototype)

A prototype/prerelease build of Dead Space 2 for the Xbox 360 from 2010-10-05 (about 3.5 months before the game was released).
==Notes==
* Only the first disc of the two disc set has been recovered and preserved.
* Printed label indicates this is the "alpha 2" build.
* This build is bootable in Xenia Canary [Build 122f58c9d March 26 2024]
* Accessing some of the debugging controls requires a second controller. On Controller 1 or 2:
** LB + RB + Start = Debug Menu
* On Controller 2:
** RS = Toggle No-Clip Reposition Player Mode
** LS = Toggle Debug Camera/Normal Camera
* In Debug Camera Mode, on Controller 2:
** Left Stick = Forward/Back, Strafe
** Right Stick = Pitch/Yaw
** Y, A = Up/Down
** LB, RB = Roll Left/Right
** Hold LT = Slower Camera Movement
** Hold RT = Faster Camera Movement
** RS = Bring Player to Camera + No-Clip Toggle
* Plasma cutter originally was given unlimited ammo for the duration of its tutorial, before reverting to normal ammo after defeating the gurney Necromorph.
* It's possible for the lockers near the plasma cutter tutorial area to not offer any loot.
* Originally Daina and Isaac didn't bicker and he trusted her from the get-go, with a fully recorded alternate conversation during the hospital escape horde attack.
* The British female CEC AI voice is missing, with two different male AI voices, both American, filling in. Unclear if placeholder, as audio effects are in place.
* The patient suit from the beginning of the game is equippable in the store as if it were a normal suit of armor. It lacks an oxygen level readout. Other gameplay oddities may arise. Use at your own risk.
* Suits had resale values attached, suggesting they might've been resellable at some point after they outlived their usefulness.
* A blonde female non-hostile civilian NPC can be found after your second encounter with Stross. Using debug, you can find that she still retains code that enables her to look at and turn towards wherever Isaac is standing.
* The infamous screaming washing machine originally stopped screaming after enemies attacked you.
* The infector attack at the train terminal starts differently, triggering immediately instead of when you come by the doors to the train.
* Hacking minigame has different sound effects and has a more generous timer for players to complete it before failing.
* The Pack originally spawned in a far larger wave. Likely cut down due to hardware limitations.
* There are different enemy ambushes in the Church of Unitology (both a Puker instead of the three slashers in the recruitment center, and a Pack attack if you return to the store)
* It's possible for the alpha to glitch Stasis packs to 2 units instead of 3 in a stack.
* Upgrading ammo doesn't top off ammo count in the associated weapon, unlike in the final game.
* Includes cut jumpscare lurker ambush when you drop out of the vent towards the end of the Unitologist Church chapters.
* The church elevator exploit (shoot out the above vent and a slasher won't spawn) doesn't work in the Alpha. The slasher will still spawn.
* By exploring the skybox right before meeting with Daina, you can see that the Ishimura is present, with a fully detailed 2D sprite, despite not being readily visible to the player at any point during this section.
* Instead of a religious chant, the child by the marker projector video in the Unitologist apartments has this weird... eerie artificial child laughter on constant loop.
* There is a unique physics object resembling the top of a mounted turret. It's found hovering above the ground in a hallway not long after the fight with the Tormentor.
* There's a brief animation hitch on some portions of the floor geometry near the oxygen fire puzzle.
* The Clogger Poster has an entirely different design, depicting the killer in full view with a sword, sack mask, and clogging shoes. It also states that it's "From the producers of Maverik: Zombie Hunter", the animated show advertised in the toy store earlier in the game.
* Stross and Isaac conversations originally had more direct references to Stross' hallucinations hurting him, as well as referencing the events of Dead Space: Aftermath.
* Some slightly different enemy spawns before and during the school chapter.
* When the sun prop drops on Isaac on the stage in the school, he doesn't pause and shake his head. 
* It's possible to have a glitch where you can't pick up the items from inside the lockers in the gym
* Instead of a regular soccer ball, there's three zero-g balls, like in Dead Space 1. They lack the energy ring around them, simply glowing dully.
* Potential crash bug at the end of the school chapter, right at the end, as the bell rings.
* This prototype curiously contains unreleased levels related to the Wii version of the Dead Space 2 (unreleased port). Trying to enter these levels will crash the game.
* Nicole have a second "MAKE US WHOLE". In final she only whispers it once.
