Quite possibly the hardest boss fight in the Gears of War series (to do on Insane, solo). Took me alot of attempts, even using the Super Reload mutator (very, very useful, especially against the annoying Gunkers and Drudges) it was infuriating. I'd get so far only to be gunned down by a shrieker or palace guard, that or I'd run out of ammo, both for the lancer and the hammer of dawn.
Glad I'll never have to do that again. What does everyone else think of the fight?
