Well, having done all that, I'm betting anyone can do this. The tricks seems to be doing exactly not what I did lol. There's not a single stunner/immobilizer in the entire area, and the bots use w2c ammo, so I'm betting a high con light armor build is way better -.- Those silly cans lack finesse.
And those dreadnoughts treat 98% mechanical resistance like it's wallpaper.
But yeah, psionics is critical for reasons in the first post
That was hilarious fun. You don't want a dozen dudes with high explosive grenades in the fight.
Edit: then again, maybe you guys can't with the impending psi nerf. Bwahahaha!
