Check out the official Alpha/Beta documentation thread for a more in-depth look! http://deadrising2mods.proboards.com/thread/1733/rising-alpha-comparisons-depth-research The only visually noticeable differences in this build is the HUD, the level icon number is spaced further apart from the LV Text , and the items in your inventory flashed RED when they were about to break, instead of flashing black like in the final game. This build still has performance issues, shown by the game locking up when an item breaks, or hitting too many zombies at once. This build does not contain the Debug menu. However it has the "Return to title" debug option when preforming a button combo on the controller, similar to the next build. The main menu states "E3 Version" The build is only playable till you encounter Doctor Barnaby and after the cutscene ends it says "Coming in 2006" and brings you back to the title screen.
