Early action/adventure game that is another oldie but goodie from Synapse, published by IBM in 1984.
According to MobyGames’ description, Shamus lets you “...explore over 120 rooms to find the evil enemy. Shamus is an exact combination of Adventure (the Atari 2600 game where you roam from room to room looking for items and avoiding the dragon) and Berzerk (the arcade maze game where you shoot robots and avoid Evil Otto). If you like those two games, you'll like Shamus. A diverse array of special items can also be picked up for points or extra men. It's fun for ten or twenty minutes, but gets frustrating at times, boring at others.”
The bottom line: if you like either game that inspired this classic, you will like Shamus. If primitive gameplay in 4-color CGA graphics isn’t your cup of tea, then steer clear. In my opinion, it’s good for a few minutes of nostalgic fun, but doesn’t have the truly timeless gameplay (a la Alley Cat) to keep you entertained for long.

I remember this being hard as hell as a kid. Didn't it play the pink panther song as the intro? My sister and I used to love that part.
I still play this one every now and then. A classic. My thoughts about the DOS version did not change in the last 9 years or so.
One of the best Vic20 games, fine graphics and super fast on expert mode
whenI played this game I had to load it from a cassette and it took 45 min to load and when you lost you had to reload.
sadly the dos version crashes after loading level 1 on my olivetti m24. poor one. gonna take out my c64 then.
I have on the Vic 20 on all levels including Expert level. You face a large version of Shadow.
Has anyone beaten the game? Please info about ending!
wish i have never seen the pc version! After the c64 version this is pure ****.
