3:00 on the clock, the AI starts to get really nasty.
Me and three AI allies guard the objective, while what seems like their entire team rolls up. I take down three before I get dropped, and wait for my team mates to kill the rest. The only one left standing was the medic, who revived me. As I got back up, the next enemy reinforcement wave comes, around another flank. I vault across the fountain in the middle into their right flank and gun down three, before needing to reload. I switch to my automatic pistol, shoot another, wound and then knife the fifth. As I reload, my team mates drop the last guy. I rush forward to where they've been coming from, and drop a mine. As I run back to the objective, the mine goes off, killing the other two enemies. At the moment, there are no standing enemies on the map. As I repair my turret that I placed earlier, the enemy charge in a two pronged assault, breaching our defenses, and killing my team mates. I turn, jump, and bounce off the wall, firing the whole way, taking down one, and wounding another. I jump from the door frame, firing at the first guy, killing him, before meleeing the second, knocking him to the floor, before finishing him off with a few bullets to the head. The hack meter starts to go up, so I turn, and toss my grenade in, killing one, and knocking two others over, stopping the hack. I run in and take out the two floored ones as they get up, but get hammered by a heavy with a mini-gun. I go down right as my team mates arrive, dropping the heavy and reviving me. The timer hit 0:00, and I stood up and cheered. At 11:00 at night.
I seriously got 10000+ experience in that game. Twas glorious.
