Rescue!

In one of the of the most ambitious text-mode games ever, you pilot a hovercraft and go from island to island destroying missile launchers in order to save your abducted friends. There are various types of terrain to slow you down or block your path, while guided missiles try to destroy you. Firing and movement are independent, allowing you to fire in all eight directions as you move in any direction. Originally the game was called Hover Craft and contained only one random mission. Registration enabled eight new options. With version 2.0 the game was renamed Islands of Danger. It was finally renamed Rescue!, and added SoundBlaster effects, a learning mode, and four extra episodes with fixed placement were added. There are 8 episodes in this game, with only the first playable in the shareware version
