Hidden Palace and STiP0 present...
Dead Rising (Feb 1, 2006 prototype)
Discuss this release on our Discord server and the Dead Rising discord.
Today we have a prototype version of Dead Rising contributed by probably the #1 fan of Dead Rising, STiP0. Commonly referred to as "Pre-E3" or the "50% Build" predates the final game by 5 months. It was created as a demo for journalists in Las Vegas exactly 20 years before today, on February 1, 2006.
Throughout your time playing you'll encounter virtually countless differences from the retail version of Dead Rising. Textures, models, sounds, effects, and everything in-between is all completely different from what you're used to. This build is generally highly unstable, and was never meant to be played without the watchful eye of a Capcom caretaker.
You can check out the Feb 1, 2006 prototype here and head to the Dead Rising forum for the release.
