Easy. • Boss that chases you around a tiny room with no cover • Exploding shanks that chase you around a tiny room with no cover • Repeater shanks that chase you around a tiny room with no cover • Sniper shanks that chase you around a tiny room with no cover • Variable damage type (annoying because you can't use 1 sword to block with the entire fight. + no real cover to switch swords.) • Warsat. Nuff said. Not saying I hate it. It's one of the better ones. But I can see why people dislike it for these reasons.
