The 1991 game Trex Warrior: 22nd Century Gladiator originally went unreleased in the United Kingdom until August 1993, when it finally saw a release in the region via one of two cover disks bundled with an issue of the magazine "The One for Amiga Games". The other cover disk contained demos for Ishar 2: Messengers of Doom and Snakes, as well as another full game, Wibble World Giddy. Notably, the issue declared that both Trex Warrior and Wibble World Giddy were in the public domain, meaning that anyone could copy them as they wished.
