The best shooter?

Well I'm going to get my fourth shooter soon and I need help! I already have GTA4, Fallout 3, and Battlefield Bad Company! (and I play Cod 4 and 5 with my friends) and I need to know another great shooter! Please give your honest opinions about the game you've chosen k?

Try bioshock if u haven't tried it already. KZ2 if u r into MultiPlayer. if u dont mind playing some old titles try Rainvow six Las vegas I or II. they're intense shooters as well.

Look at the thread about 5-6 threads below this right now. It is about the bestFPS, only.

Look at the thread about 5-6 threads below this right now. It is about the best FPS, only, if that would help a little. But get Killzone 2.

killzone 2 has one of the best multiplayers i've played but the single player campain is a little lacking

Here is a few. :) Killzone 2 , Bioshock , Resident Evil 5 , Dead Space , FEAR 2 and Resistance.

Killzone 2 hands down bro..

The best online multiplayer i've played, and one of the best campaign modes in a shooter on the next gen.
The only thing missing is offline multiplayer....

But other than that, get it
