I've concussed about 5 ZOE MAXes since the 22MB patch last night/this morning and have been dying regardless, decided to try them out on myself to check and see if they were working, and lo and behold they were not. Fix it.
Buddy, I get 20 FPS on low settings in big fights. If you want me to post video, buy me a new graphics card first.
First of all, I'm not your buddy. Second, if you can get into the game, then you can record yourself getting hit by a concussion grenade at the warpgate. I know that was difficult to figure out.
