Shamus is an original arcade style game that was written for several different 8 bit computers in the early 1980's. The game is rather large, featuring a myriad of interconnected rooms. You must navigate through them, shooting your way through monsters, gathering treasures and keys. You use the keys to get through locked passages.
The game was originally sold by Synapse Software itself (who also sold Atari 400/800 and Commodore 64 versions), but was later sold through Tandy/Radio Shack (in disk format only, as opposed to the original tape or disk version).
