I believe it was in Armageddon where there was endurance mode where you would have one bar of life and would fight your way throughout the kast. I personally would love this to return.
Yep. I would love more single player content. Challenge tower was great. Would make for a fun achievement..."beat every character in the game with one life bar".
If this does happen tho i want it to be unbelievably hard. Maybe make a Hardcore endurance mode on the hardest difficulty with no health boosts and have leaderboards that actually mean something for once.
Probably should be timed too...like showing the amount of time it takes for a player to beat all the characters (for leaderboard reasons). Maybe a trophy for beating all the characters on expert?
