A spiritual successor,[1] The Solus Project, was released on PC and consoles by Teotl and Grip Digital in June 2016.

The player controls an archaeologist trapped in an underground city, armed with only an artifact that can attract or repel a large metal ball.

[5] To develop his game, Sjoerd De Jong had used several sources as inspiration: Portal for its simple and effective design, Unreal Tournament for its style and atmosphere, Tomb Raider for the mysterious and intriguing atmosphere that emanates from the individual settings and, on the whole, early first-person shooters which were set primarily in dark dungeons and castles.

[14][15] The commercial release generated a mixed critical response, receiving a rating of 68% from review aggregator Metacritic[11] and 73.83% from GameRankings.
