Thanks, hehe. Well I thought they're not really worth it. If you look closer into the stats of each DLC. Also the suits, not so cool as the ones you'll will get for free in the game (Advanced Elite Suit etc.). It's doable. Just take advantage of the many detailed guides on this very site. If ya need some more help just holla @ me.
it's not too bad. need 8 people to get the match started. there's still a fair amount of randoms lurking around there but they don't give us too much trouble. if they do, we just kill/revive them until they leave. we've done three sessions so far and i currently have 11,000 points from that.
