Defender on Tri

Defender on Tri is a 1-player arcade game for the VIC-20.

You and your Defender style ship "Skyes Limited", are the only hope for the advance exploration party that has discovered and become trapped within an ancient planetoid-sized alien vessel trapped irretrievably in the gravity well of our sun.

The player tries to navigate 4 maze levels. Each level has a number of traps including moving doors and platforms. The player has limited fuel and time to finish their mission, and fuel can be picked up as the player explores. Numerous treasures can be picked up for bonus points, and the goal on each level is to reach the base or exit point.
