Looking for an online multi fps

Hi guys

Title says it all pretty much.

Looking for an online multiplayer game. Use to play sf2, cs/s but when I went back a few months ago seems like not many ppl play it anymore.

A large player base would be preferred. Not really into vehicles.

Thanks

Scratch that, he doesn't like vehicles.

Therefore, replace it with Unreal Tournament 1999.

Shadowrun, EnemyTerritory:QuakeWars, Call of Duty 4, F.E.A.R. Combat, Any number of Half Life 1 or 2 mods, Half Life 2 Deathmatch etc.

Most have good online communities playing. Personally also looking forward to Battlefield Heroes.
