14. Dead Rising 2 (PC, PS3, Xbox 360)
A perfect match for horror fans who aren't afraid of a little camp, Dead Rising 2 can, on occasion, have up to 7,000 zombies on screen at one time. You can combine just about anything to make a bizarre weapon -- the "Hail Mary" is a hand grenade duct taped to a football, the "Dynameat" is a stick of dynamite duct taped to a piece of meat, the "Paddlesaw" is two chainsaws duct taped to a kayak paddle, and the "Spiked Bat" is a baseball bat with nails hammered though it -- plus the plot is camp gold. Dead Rising 2 is a classic in the zombie-horror genre.
You play as a former motocross champion who's looking to help his daughter out after her zombified mom bit her. The only way to help her is to get your hands on the band-aid-on-a-bullet-wound medication Zombex -- which, if taken daily, prevents full zombification. But Zombex costs money, so you have to travel to a fictional casino town where you have an opportunity to make mad money on a reality show where people kill zombies. Nothing goes as planned, making Dead Rising 2 an amazingly enjoyable zombie-clusterf**k. It's as ludicrous as it is saturated with gore, always a perfect match for a zombie-horror game.
