Well, I've gotten a bit farther, and just had the most LOL moment I've had in gaming in .. perhaps ever, at least for a single player game.
I came into an area, MDK'd everyone, then came upon a PC where it let me hack / take over the turret in the area. I thought "well damn, that woulda been fun a minute ago", but I set it to 'enemy' mode anyway and then pressed a button on the wall, which prompted the network dude to tell me that more squishies were on their way to me. YAY! I turned around, crouched, and picked up the turret robot, and proceeded to carry it around and letting it mow everyone that came after me down. Was spectacular
