This, well-loved, but short-lived game was published by Last Unicorn Games in 2000. The game was patterned after Fantasy Flight Games popular DiskWars line. Game pieces were punched out of "flats" and used as table-top playing pieces.
Last Unicorn was purchased by Wizards of the Coast around the time they lost their Star Trek license to Decipher, and so the publishing of Red Alert came to an end. A planned second set of disks was never released, but it was made available for free online.
A small, but dedicated, band of players continues to play Red Alert. There is still a Yahoo Group dedicated to collecting, trading, and playing...
Edit: Yahoo Group has since been abandoned.
