I was repeatedly told that playing through this on heroic would be a mistake. "No worries, I played Halo: Combat Evolved on heroic! I'll be fine," I said, unaware of the cosmic horrors that would await me inside. However, despite my hardship I have navigated through the valley of death, and I have achieved inner clarity.

Playing this on heroic was a mistake.
