Metal Gear Rising gets a release date, gamescom 2012 trailer
Metal Gear Rising: Revengeance has been catching a lot of heat because of the whole lack-of-stealth thing, but many Metal Gear fans are still looking forward to seeing where it's all going. This new trailerfor the game from Gamescom 2012 is pretty much the same one we saw at E3, but with a new bit tacked on in which Raiden has to fight a robot dog with a chainsaw on its head. Oh yeah.
It looks like you can tame that critter at some point, too.
Revengeance also got a release date, that being February 21st, 2013. You don't have to wait till then to have a look, however, as the Zone of Enders HD Collection will have a Metal Gear Rising: Revengeance demo on it when it releases in October.
