Dead Nation was a game which made an appearance at GamesCon 2009 it will be available on the PlayStation Network and is apparently a Zombie survival horror game, apparently this game will fill your screens with zombies, even more zombies then Dead Rising even Dead Rising 2
here is a quote from the source
it would be filled with zombies. In fact, there’s so many on screen zombies in this game, that no other zombie title in existence has the amount which Dead Nation has.
The original Dead Rising is, of course, known for its countless zombies all appearing on the screen at the same time–500 infected humans to be exact. The second installment in the gory-filled series will further increase the number of zombies appearing all at once on the screen, and Capcom revealed that literally thousands of zombies will appear on-screen at the same time. Thousands? Just wait till you play Dead Nation, then!Advertisement
And I though Left 4 Dead 2 on expert had a lot of zombies. If this turns out to be true I might just buy the game when it does come out. I am a huge fan of zombie games and really look forward for more details on this game.
