Evaluation
Moonbase Alpha launched on July 6, 2010 as a free, self-contained game published by NASA. The store description describes a complete, finished experience — a cooperative multiplayer scenario with defined objectives, leaderboards, and multiple maps. There is no mention of DLC, expansions, seasons, or planned post-launch content.
The only notable developer communication after launch was an October 8, 2015 announcement that Virtual Heroes had opened a Kickstarter campaign for a separate sequel project, Moonbase Alpha 2. That Kickstarter was never fulfilled (there is no evidence of a funded or released sequel), and the announcement does not describe any new content coming to the original game. Developer communication for the original game has otherwise been silent since launch.
With no post-launch content ever released, no announced additions to the original game, and a gameplay structure that reads as a complete, standalone package, Moonbase Alpha launched as a finished product. The completion date is its original release date.

About this game
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.
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.

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.
