: This is a fairly stupid way to set up an encounter, as it seems to be luck
: and randomness that dictates whether or not you have even a fighting
: chance when entering the cargo bay. The monsters are activated when you
: step on a polygon outside the bay door, kill the sole marine in there,
: then begin running around at random, and there's no telling where they'll
: be standing when you arrive. If you're lucky, they'll all be on one side
: of you when teleporting (i.e. leaving an empty path where you can get your
: back to the wall and get your bearings), then you can retreat to a place
: where the Raptor can't reach you to kill the Beasts before taking the big
: guy out with the Mercury. If you're unlucky, the monsters are occupying
: all possible routes of maneuvering and you're dead. Good thing that (for
: once) there's a pattern buffer right before the encounter.
Although I can't guarantee success every time, the approach I take seems to work more often than not. Once you teleport in, immediately go to the right into the small niche that is blocked on three sides. I have never seen that area occupied by one of the Beasts. Since you are blocked in on three sides, the Beasts must attack you from the front. I just stand there and blast away with my pistol, taking them out one at a time. It's close, especially with the one that throws Fire, but my experience is that I can defeat all of them on Death Wish with this approach. Leaving the previous level with 2x shields also helps.
