How insane is Insanity in ME2?
In the original mass Effect, Insanity difficulty was tiring more than it was difficult; as a max level soldier with Colossus X heavy armor, my damage reduction and health regeneration maxed out, and the at-that-point-redundant Immunity ability at its third level, I was never in any danger of dying. All the challenge in the game came from chasing individual enemies around the map, wearing down their extraordinary health bars as my massively-overpowered weapons blasted them around the room.
Heck, I fought every Geth Colossus and almost all Armatures on foot, just for kicks. It took three or four shots from a Colossus' main cannon to down me, which I tested just as an experiment. I never actually died doing this, amazingly, since you can easily out-turn them.
I'll quickly interject that I can't imagine it was like this at all for other, less overpowered classes, though.
But what about in ME2? With fewer customization options and a general shift more towards action than character building, Insanity must really live up to its name, right?
