About this game

Guess Who's Ack, Ack Again...
Mars Attracts is a theme park management game set on Mars. Play as the devious Martians from the cult-classic universe of Mars Attacks™ and build your amusement park empire, abducting humans from across history to display in customizable enclosures for the entertainment of curious Martian guests. Study humanity in their natural habitat, or subject them to whatever twisted experiments you can imagine!
Business Is Boomin'!
Take on the role of a Martian CEO 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. You won’t last long if you can’t turn a profit.
Cater to your guests’ diverse needs by unlocking a range of merch stalls, food vendors, and colorfully gruesome decorations.
Manage supply chains by assigning helpful porters to keep your park running smoothly.
Balance your books by taking out loans and customising prices with an in-depth financial management system.
Gain the approval of the colourful cast of Martian board members by completing optional missions and park inspections.
Improvise, Abduct, Overcome
Humans come in all shapes, sizes, and bounciness. Employ advanced Martian technology to procure humans from across history – from Ancient Rome to the Wild West – and build the perfect habitat to ensure they have no idea they ever left.
Launch abduction missions to Earth to capture humans from across history, each with their own set of unique traits and preferences.
Gather knowledge of humans from different time periods to learn how to construct the perfect enclosure.
Collect unique historical humans including Julius Caesar, Cleopatra, and Date Masamune.
Tailor enclosures to appeal to each human’s unique preferences using decor items collected from expeditions.
Unhappy humans won’t remain docile for long. Hire security teams and build defences to deal with rampaging humans before they trash your beautiful park and kill your innocent guests.
It's Probing Time!
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 these strange enclosed-brained creatures, or push your captives to the limit and see what breaks. For science, of course.
Unlock new buildings and staff abilities from the research tree by performing gruesome experiments on captive humans.
Dissect excess humans to construct anatomical horrors to decorate your park.
Satisfy your guests’ need for random acts of cruelty by building torture devices, running experiments, or selling merch made from human body parts.
