I was talking with a buddy of mine while playing earlier and something we think that would be pretty awesome is a campaign mode! I'm sure this idea has probably been brought up, and I'm hoping the team at Reloaded is considering this. The game engine is beautiful and the multiplayer is a lot of fun! Being able to apply it to a story based campaign mode would be so much fun! This would allow for a universe of lure behind Hawken and allow new players to get a nice feel for the game in a PvE world. There could also be a co-op mode where players team up to do missions. Just like any other fps game the difficulty would increase with progression, and there could also be different levels of difficulty overall.
It would be even cooler if the AI were programmed to challenge us, and teach us tactics that would help us succeed in the PvP environment. I know a predator style level where we would have to stealth attack and flank the enemies would be great! It's a pretty tough style to master, and playing missions that introduced that sort of gameplay would be pretty helpful!
