Dead Space 2 es un videojuego de horror de supervivencia de disparos en tercera persona secuela de Dead Space, desarrollado por Visceral Games y publicado por Electronic Arts para Xbox 360, PC y PlayStation 3. Situado tres años después de los acontecimientos del primer Dead Space, el juego sigue la lucha del protagonista Isaac Clarke contra un nuevo brote de necromorfos en Sprawl, una estación espacial sobre la luna más grande de Saturno, Titán, sin embargo la lucha de Isaac no se limita solamente a detener a los Necromorfos, sino también para salvarse a sí mismo de una demencia mortal.

Dead Space 2 Recomp
Prerelease playtest — expect bugs. No game data is included. You need your own retail copy of Dead Space 2 to build and play.
A static recompilation of the Xbox 360 version of Dead Space 2 that runs natively on PC. The whole game executable (47,739 functions, Title Update 2) is translated to C++ by ReXGlue and laid out using the game's PDB: original source folders, real function names, original file boundaries.
Dead Space 2 already has an official PC release; this project isn't a replacement for it. It has two goals:
- Portability: turn the 360 version into plain C++ that can move to ARM devices (Switch and others).
- PDB mapping: test how far a prototype PDB can name and place recompiled code directly, with no decompilation step, with every name and source file backed by measured precision.
Mods are supported through a hook API keyed by those PDB names.
Status
TU2 is now the only supported build; the tooling remains in tools/.
The campaign and Severed DLC have not been fully playtested.
- TU2 names: carried from base by proof. 45,912 are proven and 885 probable. The probable ones need an opt-in before a mod can hook them.
- Disc 2: with Title Update #2 it patches to an image byte-identical to Disc 1, so the TU2 build runs it too. The launcher supplies both discs for automatic switching; full campaign validation remains pending.
- DLC, Dead Space 2: Severed: working, but not fully playtested. The package installs with
tools/extract_dlc.pyand the game mounts it. Severed has been smoke-tested, not played through. - Multiplayer and Xbox Live features (online play, leaderboards, achievements syncing, marketplace) are not tested yet.
- Launcher: included in the playtest release, with file verification, DLC setup, display options and language selection.
- Languages: English and French voices; Spanish text/subtitles with English voices on the supported World (En,Fr,Es) discs.
- Feedback: report bugs through Issues, including your chapter/DLC, GPU and latest log. First-run shader compilation may cause stutter; restart and check whether it improves.

The prototype is a near-exact match for retail: of 22,976 functions compared by compiled size, 22,962 (99.94%) are identical. The 14 that differ are all XDK runtime code (CRT file I/O, heap); the game's own code matches throughout.
Quick start
- Download DS2-TU2-Playtest-20261017-Setup.exe (installer), or extract DS2-TU2-Playtest-20261017.zip (portable), from the release.
- Run
DS2Launcher.exe, select your own Disc 1 and Title Update 2, plus Disc 2 and Severed if available. - Verify files, choose your options and language, then launch.
Build from source: docs/BUILDING.md. No game data, title update or DLC is included.
