Game Overview

A battered starship becomes a pressure cooker of alarms, flames, hull breaches, and incoming alien fire in Catastronauts, a frantic local co-op party game built around surviving chaos together. One moment the crew is lining up a torpedo shot; the next, a solar flare fries vital systems and every room needs attention at once. Its cartoon sci-fi presentation keeps the mood playful, but the pace is ruthless when the ship begins falling apart. Victory depends less on one heroic pilot than on a crew that can communicate, prioritize, and recover from mistakes without panicking.

Up to four players share the vessel locally, running between stations to repair damaged machinery, put out fires, reload weapons, steer, shield the ship, and prepare defenses against enemy craft. Each mission turns into a fast-moving juggling act: attacks create new emergencies, while limited crew numbers force players to decide what can safely be ignored for a few more seconds. Controls are deliberately straightforward, making it easy for newcomers to contribute immediately, but effective roles and callouts quickly become essential as hazards stack up. Solo play is supported, though the experience is clearly designed around groups, including the occasional hilarious accident where a teammate dies and must be brought back through cloning.

Catastronauts stands out through its blend of spaceship combat and domestic-disaster management, treating a star cruiser like a kitchen during its busiest dinner rush. Randomized-feeling crises, escalating stages, and the need to move constantly ensure that even familiar crews rarely handle a round in exactly the same way. Fans of Overcooked’s cooperative shouting matches will recognize the appeal, though the focus here is more on defending and maintaining a shared machine than preparing food. It suits casual parties, families, and co-op veterans looking for a compact, approachable challenge, while players seeking a calm single-player space adventure should look elsewhere.

Do I need to run the game as administrator?

The game won't launch — what should I try?

My antivirus is blocking the game — is it safe?

A warning needs to be investigated; the download source alone cannot confirm that a file is safe. Keep your security software enabled and review the detection details. Do not run or restore a flagged file unless you have verified that it is a false positive. If you are unsure, leave it quarantined.
