Creepsoft was a Spanish programming group, creator of the games Rescate Atlántida and A.M.C., published by Dinamic.

Pablo Ariza, responding to an advertisement in MicroHobby magazine, would contact several programmers and graphic artists interested in creating games for the 8-bit machines of the moment. Finally, the group would be made up of Ariza himself, two childhood friends (Juan Carlos Naranjo and José Antonio Martín) with whom he had previously collaborated, and Gustavo Tallón (creator of the advertisement published in the magazine).

The team's name makes a nod to a film of the time (CreepShow), their first project being a game with an underwater theme, using a technique similar to that of Cyberum, from Ultimate. The game was presented to Dinamic as the only desired option with "Rescue Atlantis" the first Creepsoft published game.
