Mars Attracts is a theme park management sim set in the retro futuristic, B-movie inspired universe of Mars Attacks. Build your park your way: Abduct humans from across history, display them in customizable habitats and cater to the every whim of your Martian guests. Study humans and learn how best to exploit them for profit. But watch out for escapes!

Take on the role of a Martian park builder and confront the challenge of theme park management — craft the perfect red planet tourist attraction, complete with human enclosures, death-defying rides, and a carefully selected range of amenities.

Martians want to visit a park that lets them observe those fascinating humans up close. Balance human happiness with guest satisfaction. Design ever more elaborate attractions while also keeping an eye on your limited budget. You won’t last long if you can’t turn a profit. 

Humans come in all shapes, sizes, and bounciness. Employ advanced Martian technology to procure humans from across their historical periods – from Ancient Rome to the Wild West – and build the perfect habitat to ensure they have no idea they ever left. 

Humans may all look the same, but new research suggests that each one has their own unique personality. Remember to tailor enclosures to appeal to each human’s preferences – or else you may find yourself dealing with an enraged human terrorizing your beautiful park. 

For centuries, Martian explorers have scoured the galaxy for signs of intelligent life. So far, no luck. Nevertheless, there is much to be learned by studying human behavior. Maximize their happiness to enlighten your guests on the mysteries of this strange culture, or push your captives to the limit and see what breaks. For scientific purposes, of course.

Mars Attracts will hit early access on Steam starting September 16, 2025. 

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

“The Early Access version features many hours of content and all of the game's base systems, including construction, financial and staff management, human abductions, rides and amenities, guest happiness, multiple maps, and more. The game has been fully tested and localized, though if there are any new technical issues discovered by players we will be addressing them throughout Early Access.”

“Throughout Early Access we plan to update the game with new content - maps, human enclosures, amenities, and more. We also intend to integrate player feedback into the gameplay, deepen the interweaving systems related to managing your park, and fix any bugs that may be discovered.”

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-twelve 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.
