About Moonbase Alpha

✦ AI summary

Lead a team of up to six astronauts in a frantic race against the clock to repair a crippled lunar outpost's life support system after a meteorite strike. Coordinate with your crew to strategically deploy rovers and repair robots across an authentic moonscape, with multiple solution paths and leaderboard competition keeping each playthrough fresh and challenging.

NASA has once again landed on the lunar surface with the goal of colonization, research, and further exploration. Shortly after the return to the Moon, NASA has established a small outpost on the south pole of the moon called Moonbase Alpha. Utilizing solar energy and regolith processing, the moonbase has become self-sufficient and plans for further expansion are underway.
In Moonbase Alpha, you assume the exciting role of an astronaut working to further human expansion and research. Returning from a research expedition, you witness a meteorite impact that cripples the life support capability of the settlement. With precious minutes ticking away, you and your team must repair and replace equipment in order to restore the oxygen production to the settlement.
Team coordination along with the proper use and allocation of your available resources (player controlled robots, rovers, repair tools, etc.) are key to your overall success. There are several ways in which you can successfully restore the life support system of the lunar base, but since you are scored on the time spent to complete the task, you have to work effectively as a team, learn from decisions made in previous gaming sessions, and make intelligence decisions in order to top the leaderboards.

Key features:


Team up with your friends...

The fate of a lunar colony rests on the shoulders of you and your team. Communicate and coordinate efforts with up to six players (LAN and internet) by using voice over communication.
Utilize the latest in NASA technology...

A fully functional rover that utilizes lunar physics is available to transport both players and supplies to all reaches of the lunar colony. You can build and pilot your own repair robot in order to fix crucial systems before time runs out.
Immerse yourself in an awe-inspiring lunar environment...

Take your first steps on the moon's surface in a truly accurate lunar moonscape that is unmatched in any other application.
Compete with your friends to reach the top of the leaderboards...

Do you have what takes it to be number one? When you win, your score will automatically be posted to the leaderboards for everyone to see.
A unique experience each time..

With multiple paths for game success, you'll need to learn to work effectively as a team, learn from decisions made in previous gaming sessions, and make intelligent decisions in order to top the leaderboards.
Tailor your game to fit your gameplay style...

Do you want to play with two players or six? With multiple game maps you can select the game environment that best suits your team's needs.

This sacramental simulation demands a frantic, degrading exertion from the mortal vessel, and to actively repair one systematic failure is to invite a cascade of structural anomalies elsewhere, leaving one's interval of time invested sabotaged. Be that as it may, it is a brilliant educatory ritual.

Games like Dying Light, where nightfall changes the rules

Games like Dying Light are easy to find if you only want parkour or only want zombies. These eight keep the part that matters: a city that becomes a different place after dark.

Games like Portal 2, where one idea carries the whole game

Games like Portal 2 all share one habit: teach a single impossible trick, then spend a campaign breaking it. From rewinding objects through time to Escher geometry that loops back on itself.

Planet Coaster DLC: skip the collection, buy the packs

The Planet Coaster DLC catalogue closed in 2019, so there is no curve left to wait out. Our record shows the collection bundle costs far more than assembling the same packs one by one.

Toxic Commando Game Pass: subscribe, or buy the key?

Games like Titanfall 2, for the pilot or for the Titan

Titanfall 2's campaign changed its own rules every mission. Games like Titanfall 2 that keep one part of it — the wall-running, the mech, or a campaign that never settles.
