Good call with "The End". That one didn't cross my mind.

Did you know there's a part in that game (a cutscene) where The End is being wheeled by another character, that just after it ends you could get out your sniper rifle and shoot him in the head? If you do, the boss fight with The End will be skipped.

Another way is to get to the boss fight, turn off your console and wait 7 days. When you load your game back, The End has died of "old age" and you can continue on.

Pretty crazy, but I fought the battle the way it was meant. Although I'd play for about 15 minutes (maybe get one hit on him), pause it for a while, play for another half or hour so, pause it and take another break, and so on...it's a different and fun boss fight, but definitely takes its toll on your patience.
