Chaos Domain is a game about shooting bad people in the face.
Apart from that, it is also a run and gun platformer, powered by Unreal Engine. The game is highly influenced by games from 8-bit and 16-bit era, including Contra/Probotector series, as well as titles like Abuse and Doom Troopers.
The game is set on a huge spaceship occupied by chaos cultists, where the main character (who clearly looks like a hi-tech version of the god Anubis) must kill everyone in sight. The game is obviously not story-driven, it’s all about action.
