Has anyone actually been able to finish one of these quests?? I keep doing one wave and then the next wont come, have to save and quit and start over, after first wave no one comes. what the hell is this
Sounds like a glitch. I had a Buzzard get stuck in the wall for me one time, but the only problem I had was Wave 5 playing solo Zer0.
Try leaving the area and doing another quest then coming back because that just sounds like an enemy is getting stuck in the wall or something along those lines.
Edit: Now that I think about it, I do remember one of the waves taking a while to arrive. I would be more than happy to pop in your game to actually see what's going on. --- Intel Core i7-3770K Ivy Bridge 4.5GHz | 8GB Samsung RAM DDR3 1600 (11-11-11-28) | SLi eVGA GTX 670 4GB VRAM 1006/1084/6008 | ASUS 27" Monitor @ 2560X1440
If you see the red spot for an enemy stuck in the wall you may still be able to kill it even if it looks hidden. or behind cover -- just shoot the wall. Usually they spawn from about the same locations.
