Is brink worth it?
No,it's easily one of the worse games I've ever played,and I've played some shitty games.
Edit: I realize I should give you some reasons why it sucked.
The AI. You're teammates are retarded and useless. They can't help you catch objectives,nor do they help hold off the other team while you try to catch an objective. It's basically you vs 6 other AI (I think that's how many). Plus the other team is always 10000x times smarter then yours once you get into the later levels,which reminds me,the first half of this game is insanely easy,then the last half is hell because of your dumbass teammates.
I hope this helps you out,cause this game is really not worth $5.
