As indicated in the YouTube comments, this arcade game was MASSIVE in the early 90’s. Fun game, but really fun when other players jumped in to help you fight. On the big two monitor machines it was a six-player maximum, so all the X-Men could battle their way to final boss Magneto. (Whom I never reached.) Impressive this guy did it by himself.
If nothing else, just watch the intro.
First thing I thought of: Ace and Gary.
Hahaha
