I just played around with it a bit more, and it has the worst MP ever. Or the best. See, apparently it does have voice chat. Add that up with the type of people who are playing this online when they could be playing a dozen far better MP shooters out there and you have hilarity.
I suck and no one is talking except for two guys on the other team, who are just chirping. So, I figure it'll be fun to pretend like I killed them after every time they killed me. I was so right.
Some Dude: "Gpw...can I ask you a question? Why are you so fucking gaaay?!"
Awesome, but not as awesome as this:
Me: "You're only gay if you take it. Like you just took my boot to your face while you were bleeding on the ground. After I dominated you... with my gun."
Some Guy: "Fuck you, that was you. You just died. You haven't even killed anyone."
Me: "Look man, this is serious business and I don't need amateurs like you trying to have fun while I'm at work. My job is showing chumps like you what it feels like to get shot by motherfucking aliens".
Some Guy 2: "What the fuck is wrong with you?"
Me: "I HATE FUN"
By itself, worst MP game ever. Combined with chumps it might be the best.
