I put a scarey amount of hours into battle field 2, and bad company 2 on PC, amazing games, especially if you get into a mature balanced squad where everyone plays thier part properly. Voice coms are vital for this.
One four or five hour session that sticks in my mind, we had two special ops guys, one assault, an engineer and I was medic, we holed up in a building and no one could touch us, only the special ops guy’s were shooting out the windows, backed up with the odd grenade /rocket from the rest of us.. As soon as the fighters took any fire I’d heal them immediately, or I’d defibulate the if they took a direct hit, and the assault guy kept them in ammo, and me in medi packs.
The other teams literally couldn’t touch us! We won round after round after round with insane scores.
