I bought the 20$ founder's pack to get into the beta for Firefall. That said, the game is clearly in BETA. Stuff changes, the whole game isn't there... but I've been having fun with it.
People seem to be impressed by the cell shading. It's nice, but after COH, cell shading really looks juvenile.
Also, it's an FPS, but it's been fun. The weird thing is you only have one character, but you can have multiple "battle frames", i.e. classes. You switch into a battle frame and spend your XP to buy upgrades, and can craft better ammo, ability stuff etc once you get into a tier 2 battle suit. Eventually the goals is to have like 5 tiers of battle suits. As is there are only 2, with tier one having 1 suit and tier 2 having two. Oh yeah, and you gain XP within your battle frame and the XP doesn't transfer to other battle frames but other resources in the game are on you, not your suit.
http://firefall.wikia.com/wiki/BattleframesSo far I have tried
Assault Tier 1 (splash damage)
Assault Tier 2 (Firecat)
Biotech Tier 1 (focus on healing, but with poison gas)
Biotech Tier 2 (Reckluse frame)
Engineeer Tier 1 (turrets)
It's worth the 20$ to try it out if you're interested. I'm on intermittently and will be off for awhile with the holidays, but feel free to friend me.
