I really love this engine and the combat, but the maps are pure junk. So many one way doors that prevent you from being able actually explore. The most frustrating thing is trying to complete a challenge, say kill multiple with the super shotgun and the LAME A$$ glory kill mechanic takes over leaving one alive and able to handle four rounds when staggered, and NO i am not using the lame rune. Samual Hayden is a total jackass and having to listen to him makes me wish the devs died in a fire. I usually play to the point I am forced to interact with Hayden and vega and the restart the game. I beleive in truth, and truth is the effort put into the engine is AWESOME, the maps, not so much. The argent tower belongs in a mario bros game, not doom.
