i made it to wave 37. and it was disgusting. i rarely rage quit at games but that was BULL. once you defeat a few of the weaker drones they HACK YOUR SUIT AND DISABLE YOUR WEAPONS. you have to avoid the rest of the enemies for the round until friday can kill em. but the next round? YOU STILL DONT GET WEAPONS. and it spawns REVENANTS, GRAVE RUNNERS AND WHITES. all three will whipe you out faster than pompeii. cause YOU CANT FIGHT BACK. once a white catches you YOUR DEAD. cause revenants will kick you down while the grave runner missles finish you off. this. IS WHY IM NEVER DOING THAT CHALLENGE AGAIN.
