MYM Got Hacked?
Maybe it's me but I just had a player run one of my outposts with 69 grenades and 69 phoenix pods. He was also able to continuously double jump meaning he could stay airborne indefinitely. Now I'm not sure that's normal for this game. Needless to say he was a PC gamer because, you know the old saying, "when the going gets tough the PC gamers get hacking".
Thankfully my outpost is very brutal and, even with all the grenades and pods it still took him over 20 tries to escape with the GenMat.
