PS2 multiplayer shooter game? ۔
The shooter theme, not the PS2, is going into an opt-in adventure mode that leaves a maximum of 2 controls online.
Coop Item 007 Everithing or Nothing and Star Wars Battlefront 2. Both work great, or better. Or don't play; just get out, and much more. Search and see, you'll love the video. These are just two of the PS2's favorite musicians, and that's why I play so much.
And to play against this theme you should also mention the above, and all the medals of more than 2 controllers give pre-game at the same time for up to 4 years. Call of Duty also offers to play against Modern Warfare 2 (I'm not wrong).
