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 This Build was created as a "Demo" for a gaming convention in Las Vegas in early 2006, as well as for GDC a few months after. This build is not very different from TGS 2005 as most of the assets are still just as early, however a new mall has been added to this build which is starting to resemble the Final games mall, with the exception of it being very early. The security room is one of the stages that went through the biggest changes, as it has extremely reflective surfaces and the model is very different from the Final game. Various areas around the mall are not even playable, such as Paradise Plaza, the Roof Top, Wonderland Plaza, just to name a few.
