I recently went back to that local arcade and I realized upon replaying the game that the gun seemed to jam every so often and especially when the player was attacked; I don't know if this was a game mechanic or glitch but it was annoying. Half an hour later I noticed that the gun wouldn't fire at all so it looks like the cabinet I played was busted. Regardless, I dot feel a need to give the game more credit since its predecessor, Aliens: Extermination, had its own fair share of glitches that should have been fixed by now and Armageddon seemed to be the least popular game at the arcade for one reason or another.
