This probably isn’t what you were expecting out of a combo video spotlight, but there’s some insane footage out there for Capcom’s oldschool Aliens vs Predator side-scroller. I don’t know what else to say other than go check it out:
Everything is explained in English subtitles and there are literally dozens of combo, glitch, and research videos on AvsPadmirer‘s channel dedicated to the game. If you’ve ever played it, you won’t believe how advanced some of this stuff gets. If you happen to enjoy this video, you’ll probably like almost every other one posted on his channel too.
