Just beat it yesterday on hard and it was breathtaking. The combat is crazy fun, using strategy to thin the enemies numbers like traps, signs, and even the environment ie: bottle necking the opponents so they can only come at you 1 at a time. Although i was a bit saddened by the ending (not going to tell it :P).
Gonna try an Insane run through but i don't have high hopes for that.... I tend to die alot :P
