Sewer Sam

Sewer Sam is a game released for the ColecoVision and the Intellivision. The ColecoVision version is one of the few games from that period that had built-in voice synthesis capability. It was followed on the ColecoVision by Squish 'Em Sam.

Gameplay
One or two players compete to guide Sewer Sam through myriad mazes of danger-filled tunnels searching for three enemy submarines that have invaded the city's sewer system. But watch out for subterranean dangers, as Sam dodges and shoots snakes, crocodiles, bats, rats, web-spinning spiders, and more! Enough to make even the stout-hearted shudder...as Sam searches through wet and dry tunnels for the ultimate showdown!
