This game truly rocks. It had a Dead Space game feel at the beginning but it all ended and went where Half Life, Fall Out 3 failed to go. Even Silent Hill wasnt as scary and gripping as this game is. It's bad ass.. The levels are massive, your killing replica soldiers and zombie type monsters that are fast and crawl on walls and swing from the rafters. Multiple ways to go and slaughter people. Also ghost will zoom buy and resurrect the dead soldiers and they come up with machine gun in hand and you have to slice them back down. The graphics are amazing and the detail of the game. If i had 60 to blow on a game, i would try to get it =)
