So, Reach has been out for almost a week now, and I've just started towards the "A Monument to All Your Sins" achievement in the game. I must say, it is the hardest thing I've ever done in a game. As you may know, the achievement requires you to beat the game on Legendary, by yourself. The game is annoying me so much with the ridiculous amounts of damage the enemies do now. A Grunt can kill me in 2-3 hits. It's ridiculously hard, at least for me, but I'm not the greatest player. I had nowhere near this much trouble trying to beat MW2 on Veteran. So anyone else have this problem, trying to beat a game on the hardest difficulty? Not just Halo: Reach though, any game.
