I want a game I can just jump in and start killing things. The two online games I've been playing recently have their problems, though.
AVP2 - great fun but most servers have people that are crack shots with the sniper rifle (1-hit kills), and its got hackers all over the place.
Infiltration - since its a UT mod (not UT2k4), there are only 2 servers that ever have people on it, and its old enough that the only people that still play are the best, and its kinda boring for someone who hasn't played in enough months to be very rusty.
Of course, I'd like to go get myself a newer game, but I really don't want to drop anything over $30 for it (especially when I'll be dropping $40 on Theif3 soon). Any good online game that's simply a fun fragfest? Don't say CS... far too boring (played it from Beta 6 until a year or so ago... it just got boring, and I'm sick of de_dust). What'd be nice is a good co-op game... the original AVP had a game where you play as marine or pred and the computer just sent hordes of aliens at you. Instant stress relief in seconds...
