To that end, the organization establishes a self-sufficient base on the south pole of the moon called Moonbase Alpha. And then something goes terribly wrong, and everyone might die. This is why we can't have nice moon colonies.

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. 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…

Price History Overview

USD uses SteamPulse's own locally recorded daily store snapshots, so this overview reflects the exact regional price history that SteamPulse has captured for this currency.

Coverage And Tracking Window

  • Snapshots: 1
  • Coverage: Sep 24, 2026 to Sep 24, 2026
  • Lowest observed: Free
  • Highest observed: Free

Moonbase Alpha's USD price history spans from Sep 24, 2026 to Sep 24, 2026, with 1 recorded snapshot across 1 calendar day. Each row records the available final price, listed base price, and discount metadata for that observation. Within this coverage the lowest recorded price is Free, the highest is Free, and the first visible tracked price is Free. These comparisons apply only to the snapshots SteamPulse holds; missing observations can contain changes that are not represented here.

For USD, SteamPulse uses locally captured regional storefront snapshots and does not reconstruct older prices with exchange-rate conversion. The chart and table show the values recorded for this exact currency from the stated coverage start. Additional snapshots extend that record, but they do not fill unobserved days or prove what the storefront displayed between observations.

Discount Windows And Sale Timing

  • Discount windows: 0
  • Discounted days: 0 days
  • Deepest markdown: No discount tracked
  • Latest sale window: No sale window tracked

Moonbase Alpha's tracked USD rows do not contain a discount window. This means no available snapshot in the stated coverage has usable discount metadata; it does not prove that the game was never discounted. Missing snapshots or archived rows without complete metadata can hide a sale, so SteamPulse does not infer pricing strategy from this absence.

If a later snapshot includes discount metadata, it will appear here with its recorded depth, price, date, and sale name when available. Until then, this section should be read only as a description of the available rows, not as evidence about the publisher's promotion policy.

Observed Price Changes And Stable Runs

  • Observed price drops: 0
  • Observed price rises: 0
  • Longest stable run: 1 day of uninterrupted daily tracking
  • Current run: 1 day of uninterrupted daily tracking

Outside rows carrying discount metadata, the tracked price has not recorded a separate price rise or drop yet. That means the observed undiscounted level has stayed stable across the snapshots SteamPulse currently holds. This is a statement about the recorded coverage only; it does not prove that an older or missing price change never happened.

The longest unchanged price stretch in the current record lasts 1 day of uninterrupted daily tracking at Free, from Sep 24, 2026 through Sep 24, 2026. Among rows without discount metadata, the longest unchanged run lasts 1 day of uninterrupted daily tracking at Free. The latest run records Free for 1 day of uninterrupted daily tracking as the same recorded undiscounted price. Run lengths describe consecutive stored observations only and do not establish that a price is permanent.

Latest Snapshot And Sales Context

  • Current price: Free
  • Current list price: Free
  • Distinct observed prices: 1
  • Source mode: SteamPulse local tracking

The latest tracked snapshot records Moonbase Alpha at Free in USD, with no active discount metadata. Across the available history SteamPulse has recorded 1 distinct final price in this currency. This supports comparisons with the lowest, highest, and most common values present in the retained record, subject to the stated coverage limits.

The live sales view and Steam sales record provide calendar context for these dates. A date overlap can be compared with a named Steam event, but it does not prove why a publisher changed a price. As new daily rows arrive, this overview recalculates its observed prices, discount windows, and run lengths automatically.
