Difficulty Level Naming

1. -> Fate
2. -> Veteran
3. -> Exile

hard-cruel-ruthless-unforgiving-doomed
when you enter the fifth difficulty you are doomed from the start. lol

I agree with keeping it along the theme of exiled.

desolate -> exile -> banished -> forsaken

1.Dread
2.Chosen
3.Gore

Crucible, Hades, path to glory, Redemption, Vengeance.

these could fit well if in the final difficulty you could complete your path of exile.

Path of Hopelessness

backstabbing

Path of anxiously watching the beta timer

If you do decide to go the "path of _____" route I think that path of exile should be the 2nd to last difficulty. This way you get that feeling of "ohhhhh sh*t here we go!!!" once you read "path of insanity" or whatever you decide was the most fearsome name.

I would love a name that really makes the difficulty impossible:
-Grim
-Hopeless
-Futile
-Fatal
-Suicidal

Something to just relay a message to the gamer that the difficulty should not be messed around with.
