Totally Safe Moon Project FAQ: Price, Co-op & PC Specs

What does this FAQ cover?

Buying and running Totally Safe Moon Project on PC: multiplayer limits, specs, price, Steam Deck status, redeem codes, and the developer AI disclaimer. Gameplay steps live in the walkthrough; stack advice lives in tower building tips.

How many players can join online co-op?

Steam’s short description says online co-op with up to 3 friends, and the feature chips include Online Co-op and Co-op. That is four players total with the host. Invites start from the garage Invite Friends kiosk (multiplayer guide).

Does the game support crossplay or split screen?

Crossplay: Steam lists Windows only and does not show Cross-Platform Multiplayer.

Split screen / couch co-op: Steam lists Online Co-op but not Shared/Split Screen or Local Co-op. Use separate PCs on an online session.

What are the PC system requirements?

Per the Steam store page (November 1, 2026):

Steam also requires a 64-bit processor and operating system in both tiers. macOS and Linux builds are not offered; the store lists Windows only.

How much does the game cost on Steam?

Steam API pricing on November 1, 2026:

Steam’s price data does not show when the discount ends. mxdwn (October 30, 2026) reported the launch sale ends November 13, 2026. Always read the live price on the Steam store page before purchase.

Are there redeem codes?

No on-store redeem system. The Steam description and features do not mention promo codes. This is a paid title; search traffic for “codes” usually means gameplay help. Start with the walkthrough and gravity gun upgrades.

Was the game made with AI?

The Steam About This Game section states verbatim:

No AI was used in the development of this game!!!

We repeat the developer line only. Community debate about tools or assets is outside this FAQ.

Does it run on Steam Deck?

On November 1, 2026, Steam’s Deck compatibility check reported the status as unknown, so there is no Verified or Playable badge yet. Minimum specs call for a GTX 1060-class discrete GPU. Treat Deck play as untested until Valve publishes a rating or you confirm performance yourself.

Does Steam list a playtime estimate?

No official hour count appears on the store page. Session length varies with co-op skill, collapses, and optional achievements (Chaos Mode, Fall Damage, height hunting). See all achievements for optional goals.

What languages and achievements are included?

Languages: fourteen interface languages per Steam: English, French, Italian, German, Spanish, Japanese, Korean, Polish, Brazilian Portuguese, Russian, Turkish, Ukrainian, Simplified Chinese, and Traditional Chinese.

Achievements: 44 trophies, including height goals, UFO and Asteroid Rain events, National Heroes for destroying the asteroid, and optional Chaos Mode / Fall Damage finishes. Details sit on all achievements.

Still need gameplay help?

• Walkthrough — height milestones, laser finale, campaign order.
• Multiplayer & co-op — invites, four-player limit, platform limits.
• Tower building tips — Gravity Gun placement basics.
• Objects and secrets — interactables as we verify them.
