Arctic Fox

Ahh one of my original favourites on the XT platform. Arctic Fox is trough to beat, but the game world is the same each time so you can get better as you learn to play. It is chock-full of strategic control that is not unlike mechwarrior. It can be a blast (pardon the pun) flying guided missiles, or roving on autopilot while dumping mines behind. But take care, resources are limited. Speed adjustment may be needed for your emulator (and your reflexes) as it runs fast under emulation.
