The trailer reveals that the demo for Army of Two: The 40th Day will be on XBLA and PSN on December 17th. The demo will consist of most of the first level in the game. The full game for PS3, 360, and PSP will be available January 12th.
The PSP version will be getting a demo later on January 7th in North America and January 12th in Europe.
I’m not sure if theres any sort of hype behind this title from fans. I never really heard anyone say “man we need another Army of Two game.” If you need a game with bromance and guns though this seems to be the way to go.
