I gotta give it to Ghost Recon. It was one of my first forays into the tactical shooter genre and it still holds a place in my heart. Best way to play it is of course in coop.

Anything Tom Clancy related. Future Soldier was a disappointment though, It's missing the 8-man co-op campaign from the GRAW titles. The only exception to the Clancy brand is Republic Commando which is one of the best games I've ever played.

This here .

Vegas 2 was the whole reason I got Live in the first place. I still remember my first game. It was in Three Kingdoms Casino and we won.

I think my first Tactical Shooter was either GRAW or Vegas 2. I have Vegas 1 on my 360, I want to play it but I forgotten how unforgiving it was---You can die from one hits really quickly.
