Secret Mission

Secret Mission is a text adventure with graphics for the VIC-20.

Your mission is to find and deactivate the central computer which is in control of the building. As you move around the rooms and corridors, you encounter numerous puzzles. An elevator and staircases provide movement between the 5 levels of the establishment you are trapped in.

There is a save/restore feature, and all commands are via VERB NOUN injury. The game provides hints for puzzles if the player makes several incorrect moves.
