Additionally, it is possible to launch the E3 preview version of the game by selecting the E3 front-end instead of the standard front-end. Numerous test/debugging levels are present in the map list. The early and later chapters are mostly untextured geometry, but are generally functional with the exception of the final boss battle. The middle of the game (in the fleet of ghost ships and on the surface of the ice planet) is nearly complete, although a few puzzles (in particular, the "collect all of the cross-sections of the necromorph" puzzle on the planet) are non-functional and must be skipped by using the level-select feature in the debug menu.


The entire game is present in some form, but the completeness/playability varies greatly. A pre-alpha, debug-build prototype of of Dead Space 3 for the PlayStation 3 from (about 4 months before the NTSC release build).
