Bay Route is a sidescrolling run 'n' gun game that is very similar to Contra. It was developed by Sega and Sunsoft and released to arcades in 1989. You control a commando named Tom as he runs across enemy territory to find and rescue some hostages.

The author, NitroGenesis, controls Tom as well as a second soldier to tear through more enemies in less time on his way to rescue the hostages.
