Break out the tinfoil hats—Mars Attracts is officially beaming down to Steam Early Access on September 16, 2025.
Aliens, Abductions, and Amusements
Forget roller coasters and cotton candy. In this park sim, you’re the aliens from Mars Attacks™, and your “guests” aren’t thrill seekers—they’re abducted humans plucked straight from history. Build rides, manage staff, and keep your captives entertained in the most twisted take on theme park management since… well, ever.
Early Access Details
The Early Access launch comes packing fresh maps, missions, buildings, and characters, all shown off in a brand-new teaser trailer. Expect gruesome experiments, crunchy management mechanics, and enough dark humour to make even the most ruthless Martian chuckle.
For superfans, there’s also a Supporter’s Edition featuring:
- A full behind-the-scenes featurette (about an hour long)
- The game’s soundtrack
- A 56-page artbook crammed with concept art and designs
- A bonus human enclosure
- A special Space Age character




Community in Control
Outlier, the studio behind the chaos, expects Early Access to run for about nine months. During that time, players can pitch in on Discord to help shape new features and tweak existing systems. Basically, the devs want you to have a say in how the abductions unfold.
From Gamescom to Your PC
After turning heads at Gamescom’s Indie Arena Booth, Mars Attracts is ready for the big stage. Fans loved its deep management mechanics, gruesome experiments, and cheeky retro-B-movie vibes. If you’ve ever wondered what RollerCoaster Tycoon would look like with Martians running the show, this is your moment.
Mars Attracts lands in Steam Early Access on September 16—don’t miss your chance to join the invasion.
