so, what exactly would happen in a horde mode? a bunch of aliens storming you? or a bunch of koreans? Horde is hard to execute, GoW2 did a good job but I'm talking about like, nazi zombies (yes, that's an over-used example) how exactly would it work?
When I think of horde and Crysis, I think of aliens. Waves and Waves of aliens in an open environment with tanks, vtols, and 31 other buddies to help you out.

Amen to that dude! XD

That might actually be good as a Large scale Horde Map where you have a bunch of people starting off on different ends of the map and eventually ending up all together in a main base for the battle of the century, I would have to put a Warning Message saying that you may need to lower your settings to get playable framerates, to compensate for that many aliens/koreans/cell and of course your buddies.
yeah dude, that'd make for a great battle, to have different firebases and everyone move to the main base after yours has been overrun, or if you had the choice to go help another base depending on how well they're doing. but only the last base should have any sort of vehicles, and a limited amount at that. But Pheonix, I'd love to keep in touch with you about this, I have to say you've got my attention for this (however I'm no map builder)
