I played last night for the first time in a week. I witnessed some type of hack that I hadn't seen before. I was playing as TR, attacking some bio lab. I teleported up to the teleporter room inside the bio lab which was TR owned, and had the one-way protective TR shield-doors. There was 5 or so of us in there, and also one NC guy. How the hell did he get in there? He was also flickering from being visible to invisible very rappidly. He wasn't attacking us, just running around inside the teleporter room. I managed to shoot and kill him, so I got his name and submitted a ticket. I think it's pretty rare to play this game for a single night without witnessing some type of hacking or exploiting.
