One Man Vs 100,000 Revenants In Insane DOOM 2 Map
You wouldn't think it'd be possible to conquer a level that has 100,000 enemies all trying to kill you, but this guy made it happen! Such a goofy concept, but at the same time so awesome. I'm thankful we live in a time where mods make stupid stuff like this happen!
Thanks to Kotaku for the heads up!
