I liked the first one, Not enough people though and it took FOREVER to unlock anything. Also When playing against bots it was hard shit to kill things cause the aiming was off.
You guys are crazy... I will give you the matchmaking time was freaking horrendous, but the gameplay itself was great. The aiming worked very well for me, in PvP and PvE. People just hate the aiming because it doesn't help you at all, like in CoD. It didn't take very long to unlock stuff either... I had everything unlocked within the first few days.
I can't wait for the next one, being free makes it all that much better.
