Mars Attracts hits Early Access on September 16

The upcoming park management sim Mars Attracts will hit early access on Steam on September 16, 2025. 

The release date announcement came with a new teaser trailer which highlights some of the never-before seen maps, missions, buildings and characters that have been crammed into the Early Access build. 

Following a highly successful visit to Gamescom as part of the Indie Arena Booth, developers Outlier are keen to open up their twisted management sim to a wider audience. Visitors to the Gamescom booth praised the game’s deep management mechanics, gruesome experiment system and dark sense of humor. 

Fans of the game will also have a chance to pick up a very special Supporter’s Edition of the game which includes an hour long behind the scenes featurette, the game’s soundtrack, and an 56 page artbook packed full of never-before seen concept art, illustrations and character design. Supporters will also have access to a bonus human enclosure and special character – the Space Age! 

Early Access for Mars Attracts is expected to last about nine months, with development following a player-guided approach. Fans can have their say on new features and tweaks to existing elements through the studio’s Discord. This input will play a major role in shaping the development roadmap, with the Outlier team keen to let the community have their say in shaping the game they want to play.
