There is certain to be an abundance of "Horde Mode" style gameplay in the upcoming co-op lineup. First Halo 3: ODST's Firefight Mode, and now Rebellions Aliens Vs Predator game is getting a similar co-op mode.
"Four-player co-op will be present in a Survival mode, where you and friends play as marines facing waves of Aliens. Sounds a bit like Gears 2’s Horde mode."
Survival mode, 4 player co-op, and some amazing screens (so far) have our undivided attention. Gears of War 2 is a trendsetter, and we're happy to see more games playing along!
We can expect to see this Survival/Horde/Whatever mode with AvP's early 2010 release on PC, PS3, and Xbox 360.
