Killzone?
 

Yeah, basically, I'm looking for a game to keep my PS2 alive, it HAS to be a shooting game, Either FPS or a third person shooter and MUST have a 2 player split screen option.

I repeat...

-MUST be for PS2
-MUST have 2 player split screen
-MUST be a first or third person shooter

I came to the conclusion of Killzone, but I have heard it isn't a very good FPS, but I'm not very picky. Any ideas?

I wouldn't say it was amazing, but it wasn't bad (for the PS2)

My first thought was the last Timesplitters

They are a few lurking around you could pick up.

Black
Any of the Bond games
Any of the SOCOM games

I know there are more out there. But that's all I can think of for now.

Out of those three, I'd pick SOCOM.
