Reinforcements are crazy in this update, I cleared a stronghold for a mission yesterday, I intentionally picked a smaller one at the north of the quarry that I’m familiar with. It has a couple of riot shields and you can take many of them out through windows, but after it was cleared I was standing in the stronghold deciding my next move and just got swarmed by almost constant waves of tier 3 AI being dropped off from choppers, I had to make a dash out through a door on the opposite side of the stronghold in the end.
