Alien vs. Predator Arcade
This is an arcade game that I never actually played at an arcade. A few years back I wanted to get some good multiplayer games for my arcade emulator. My fondest memories of multiplayer games back in the day hearken back to the old side-scrollers, so I picked up Aliens Vs Predator off of a top 10 list.
I never actually played an AvP arcade cabinet back in the day but I found that it was a great side-scroller that completely fell off my radar. In the end, I think I only ever played it with someone else once or twice. I did, however, play it a lot by myself and really got a lot of enjoyment beating up aliens with a giant lead pipe.
