Everyone and their mother is putting out a zombie game these days, and Tecmo is now jumping into the fray with "Undead Knights." Slated for an October release in Japan, it will feature pretty straightforward hack and slash gameplay as well as wacky environmental puzzles that involve using the decaying hordes to cross rivers, topple towers, etc. It's on the PSP so it looks to be about the quality of your average PS2 game, but zombie game completists will find something to love. With a trailer this enthusiastic, how could you not be just a little excited?
