Sony weren't lying when they said they had more PS3 exclusives to announce this year, as they've just announced another one in the latest issue of Japanese magazine Famitsu.
The game will take place in a post-apocalyptic Tokyo where mankind has been almost wiped out. Hence the name, Tokyo Jungle.
Everything points towards it being some kind of fighting game, and if the initial screenshot is anything to go by, it could be a rather frantic game. It's being developed by PlayStation C.A.M.P. and hopefully more details will surface at TGS 2010.
