SOCOM Combined Assault. Great game for PS2.
You can play LAN and online with up tp 32 people in one map competitively (16 v 16) or co-opperatively against the computer with 3 buddies. Lots of weapons, senarios and maps. Nice graphics. You can dance on the bodies of the enemy you kill, pick up thier weapons and use them, drive an A.L.S.V., tank, technical, convoy truck. Too much to list.
