Good FPS for PS2?

Anyone know any good first person shooters for PS2?

Well my top picks are:
-Half-Life
-Red Faction 1
-Timesplitters 2
-KillZone

/\ i agree!

Nice, I didn't know CS was available on PS2. Unfourtanetly Mercenaries will soon consume my video game funds! It looks too good to resist.

Killzone is the best FPS on the PS2. Half-Life sucks on the Ps2, its so much better on coputer.

CS? I never posted anything about CS. They only made that for the xbox which is really good if you have Live. Without it your going to be bored.

And Half-life is really good on both PS2 and Computer. I mean, if your used to it on computer, yeah your going to have to get used to the auto locking feature and controls but then again, half-life on ps2 supports any USB keyboard and mouse (hints the ports on the front) so you can still play the game like on the computer, but with just better graphics :D

I like killzone but i'm still hooked on Socom II - only fun online, offline is okay if your patient and want to spend more than 20 mins. per each mission.

I rented Kill-Zone, and beat it the same day. Disappointing. It looks like Project Snowblind might be good.(when it comes out)
I've liked the WWII shooters. I'm playing Call of Duty now..It's pretty realistic, and as Hard as chinese algebra. The A.I. is incredible.
