Best online 2-player co-op game?

I just helped my pal build a new PC, and he said he's really interested in a fun co-op game we can play together.  What are the best 2 player co-op games?  He doesn't like shooters that much, but he'll make an exception if it's a great one.

No MMOs, plz.

Battlefield 2142 - BF2 ?

call of duty (1) and it's expansion "united offensive" are excellent (and like 20 bux)

also, get Raven Shield, humans vs 25 bots is always fun.

Age of Empires or other RTS games

a good FPS.. Battlefield 2

As for a good singleplayer game with Co-op, not many.. Only one I can think of, is Splinter Cell games (newer ones). Also Diablo2 and similliar games.

Co-op games have died out to some degree, mainly because broadband internet is pretty much mainstream now. Games are made for internet multiplay, with less focus on co-op.

why kinda system you 2 have?

Funny, I have a lot of the games you guys mentioned, but on the 360/xbox.  I wish he had a console, but sadly, he'll never get one.  I guess he's a grown up... something I missed out on.  Guess I didn't get the memo ;)

I think Oblivion can be played on LAN or other the internet using Hamachi but I think its a mod that makes it co-op and I've also heard it can get pretty stupidly laggy.Platearmor_6

I regard a "co-op" game as a title that allows you to play through either the single player campaign or something like the single player campaign with another person.

+1 vote for Splinter Cell Chaos Theory. They dumbed down the co-op mode in Double Agent into a basic "skirmish with AI opponents" setup. SC : CT actually has dedicated co-op missions that play out like the single player maps but require teamwork to complete.

Neverwinter Nights 1 and 2 are pretty fun co-op. The game will let you play through the entire campaign with other players over LAN or the Internet (each person requires their own copy of the game, even over LAN). The previous D&D based games like Icewind Dale and Baldur's Gate also supported network play, but didn't implement it nearly as well.

Other games allow it through mods. Doom 3 has a co-op mod that works pretty well from what I've heard. Also there's a co-op mod for the original Half Life called "Sven" that's work checking out.

It doesn't work. The mod isn't even close to playable and never will be.

As for coop, Rainbow Six Vegas 2's coop is amazingly well integrated. On the downside, the game sucks.
