Managed to trap the poor sod in a loop by turn 10 or so, where we all just moved back and worth between two positions. Apex in the water below the cliff and Paradise behind one of the cliffs on the other side of the road with the crab in between in the woods by the road. Reserve until last, apex moves up a bit, breaching shot from the front, Paradise walks up (behind the crab) shots. Next turn Apex moves back to the position she started last turn while Paradise shots a second time before doing the same. The crab (who lacks visuals) moves toward Paradise's position. Next turn I reserve till last phase, for some reason the crab turns around and walks back to its previous position and faces the water. Repeat.
I forgot to take a picture of the crab, but it got cored out from behind, all back armor and one side torso lost (ammo explosion). Getting thee last two shots in was a pain since Paradise started missing or hitting the legs at the end.
Worth mentioning is that I played on the beta branch (no Bulwark for the Crab), given the exact same movements this would not have made any difference since the Crab always moved, but maybe the AI would have acted differently if it could stand still for protection? Although with the facing it had now that would still have been a breaching shot from the front and two back shots per cycle.
Fun initiative! Maybe next time a challenge with a bit more moving parts?
