I feel like this question is dumb, and I feel like the answer is no, but I really have no explanation otherwise. Before I went to bed this morning, I set up AFK farming on level 40, with a Air Raider in an Epsilon under one of the drop ships, covered by the two Grim Reaper groups. I was in a tank, doing nothing. None of the guys (as best I can tell) are able to shoot at the ship, and they haven’t when I have been watching. I woke up this evening, and the level had ended, I was on the drop screen. So, basically, I have no idea what happened. I was in 2 player, both controllers were off, and I don’t think any NPC is able to shoot at the ship. Do levels have an invisible time limit, do level end if you hit the dropped item limit, or is there a guy just randomly shooting the ship one bullet at a time that I am not seeing?
