Hookay, so this is a looong shot and I don't have much to go on but vague memories of this as a kid. Here goes.
I remember the game was in the arcade (no idea if a console version was ever made). It was a space/sci-fi style game, side scroller and I think 2-3 players. Each player was either top, middle, or bottom on long corridors. I think you could join your friends by entering elevators. I remember running around and shooting aliens and stuff. I think maybe the players to choose from were 2 guys and 1 girl. Graphically it was kinda like Rampage era. I played this at a pizza place during soccer season, my friend and I loved it. As for the year.. hmm.. man, maybe late, 80s/early 90s. Well before '93 easy.
I have no idea who made the game either. I was watching some "lets play" stuff on youtube and this game popped into my mind. I would love to download this if some sort of version exists. Alas, the name escapes me
