Gloom is an attempt at recreating Doom for the Amiga. In 1995 this was a big target for programmers, as it was felt that the Amiga 1200 was capable of bringing the first person 3D action to life. Gloom was written by New Zealand’s respected Acid Software team and published by Guildhall. The emphasis was placed on action, rather than collecting keys and negotiating through maps. Gloom is probably one of the most anticipated Amiga only FPS games and had a very huge popularity. You can download the source code on GitHub.
