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: Wibble Mania! 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.
