Delta Force Black Hawk Down: Team Sabre
This has got to be one of the most underrated games on the PS2 by far!!! Both Blackhawk Downs are pretty good games IMHO. The single player is pretty solid, with different support systems (Assault, Medical, Recon, etc..) The A.I. can be a pretty good teammate if your playing solo. The Multiplayer is where it's at!! Having 4 players playing at the same time is great!! My brothers and I still play this to this day on the PS2, and I highly recommend it to casual to even hardcore gamers out there!!!
