Totally Safe Moon Project How to Play With Friends: Co-Op Setup and Team Tips
Learn Totally Safe Moon Project how to play with friends: online co-op for up to 4 players, tower-building roles, Gravity Gun tips, and laser delivery strategy.
The Earth is about to be flattened by a giant asteroid, and the only escape route is a tower you and your friends stack yourselves. If you're searching for Totally Safe Moon Project how to play with friends, the short answer is online co-op for up to four players — but the difference between a wobbly pile and a working launch tower comes down to how you divide the jobs. This guide breaks down the co-op setup, the roles that keep a physics-based build stable, and the teamwork that gets the laser to the top.
What Co-Op in Totally Safe Moon Project Actually Offers
According to the official Totally Safe Moon Project Steam store page, the game launched on October 30, 2026, from developer Fake Moon and publisher rokaplay select. The store description frames the premise simply: an asteroid is inbound, and you build a tower to the Moon using whatever you can find — fences, boxes, houses, even clouds — to deliver a laser and save humanity.
The multiplayer details matter before you invite anyone:
| Feature | What the Steam Page States |
|---|---|
| Player count | Solo or online co-op with up to 3 friends (4 total) |
| Mode type | Online co-op |
| Genre | Simulation |
| Perspective | First-person |
| Key tool | Gravity Gun |
| Progression | Abilities, items, and upgrade points earned as you climb |
| Achievements | 44 Steam Achievements |
| Price at launch window | $5.99, discounted to $4.49 during the introductory offer ending November 13 |
One important note: the store lists "Online Co-Op" as the supported multiplayer feature. The user-defined tags include "Split Screen," but tags are player-applied labels rather than official feature confirmations, so plan around online play unless you see otherwise in-game.
Is There Local or Split-Screen Co-Op?
The store page's feature list names Single-player and Online Co-op. It does not officially confirm a local split-screen mode. If couch co-op is your goal, treat that as unconfirmed and verify in-game before promising your friends a living-room session.
Totally Safe Moon Project How to Play With Friends: Setup Steps
Because the store page does not publish a step-by-step lobby walkthrough, the checklist below is a practical starting sequence based on the confirmed online co-op structure. Expect the exact menu labels to differ slightly.
| Step | Action | Why It Matters |
|---|---|---|
| 1 | Everyone buys and installs the game on Steam | All players need their own copy; Family Sharing is listed, but simultaneous play rules vary |
| 2 | Confirm each player meets the minimum specs | Co-op still runs on each player's own machine |
| 3 | Launch the game and choose the online co-op option | Co-op is the mode built for friend groups |
| 4 | One player hosts and invites the others | Up to 3 friends can join for a 4-player team |
| 5 | Agree on voice chat before you start stacking | Timing matters when a tower is wobbling |
| 6 | Assign roles (see the next section) | Prevents four people grabbing the same box |
Check Specs Before You Invite Anyone
Nothing kills a co-op night faster than a friend whose PC can't run the game. The Steam page lists these requirements:
| Component | Minimum | Recommended |
|---|---|---|
| OS | Windows 10 (64-bit) | Windows 11 (64-bit) |
| Processor | Intel Core i5 @ 2.5 GHz | Intel Core i5 @ 3.0 GHz or AMD Ryzen 5 |
| Memory | 8 GB RAM | 16 GB RAM |
| Graphics | GTX 1060 or RX 6600 XT | RTX 2060 or RX 7600 XT |
| DirectX | Version 12 | Version 12 |
| Storage | 4 GB available space | 6 GB available space |
Both tiers require a 64-bit processor and operating system. If your group has one player on older hardware, the minimum tier is the bar to clear — not a suggestion.
The Four Roles That Make a Co-Op Tower Work
The game's core loop rewards coordination more than raw speed. The store page describes three phases: build a tower, upgrade as you climb, and carry the laser to the top to destroy the asteroid. Each phase suits a different job.
| Phase | Role | Main Job |
|---|---|---|
| Build | Scout | Finds usable objects nearby and calls out what's available |
| Build | Stacker | Places objects with the Gravity Gun and keeps the base wide |
| Build | Stabilizer | Watches for tilting sections and reinforces the weak side |
| Upgrade | Runner | Pushes ahead to trigger ability and item rewards |
| Laser | Carrier | Moves the laser upward while others clear the path |
| Laser | Guard | Keeps the route clear so the carrier doesn't drop the payload |
Why the Stacker and Stabilizer Pairing Matters
Physics-based stacking is the riskiest part of a run. The store page's own pitch leans on that tension — it compares the concept to Only Up, but with you as the architect. In practice, one person placing objects while another watches the tower's balance from a distance catches problems the stacker can't see from directly above the build.
Why the Gravity Gun Deserves a Dedicated User
The store page explicitly notes the Gravity Gun "will come in handy." Rather than four players swapping it constantly, give it to your most patient builder. A single consistent hand on the Gravity Gun means fewer accidental knocks and a cleaner stack.
Upgrade Timing: Don't Let Everyone Climb at Once
The store page states that climbing higher earns rewards like new abilities, items, or points used to upgrade gear, and that skills get "crazier" the higher you go. That creates a coordination question: who climbs first?
| Approach | How It Works | Trade-off |
|---|---|---|
| All climb together | Whole team ascends at the same pace | Everyone shares risk if the tower fails |
| Runner first | One player pushes ahead for upgrades, others hold the base | Runner gains abilities faster; base stays secure |
| Rotating runner | Players take turns climbing and upgrading | Slower individual progress, steadier overall build |
A rotating runner keeps the team's upgrade curve even while someone always watches the lower sections. Since the store page does not detail how upgrades are shared or applied, treat this as a coordination framework rather than a confirmed mechanic.
Bringing the Laser Up Without Losing the Run
The final phase is the one that tests your group the most. The store page describes working together to bring the laser you built in your garage to the top of the tower and blow up the asteroid. That means the laser has to travel the same route you built — and a fragile tower plus a heavy payload is a bad combination.
| Laser Phase Tip | Reason |
|---|---|
| Widen the top platform before moving the laser | Extra surface area gives the carrier room to maneuver |
| Clear obstacles from the climb path first | Fewer collisions means fewer physics surprises |
| Have the guard trail the carrier | Someone behind can spot a collapsing section early |
| Move slowly and in stages | Rushing a physics object up a tower invites disaster |
Keep the Tower Stable While the Laser Moves
Reinforce the base before the laser leaves the garage. The store page doesn't specify how much weight a tower can hold, so the safe habit is to overbuild the lower third rather than test the limit with your only laser.
Communication Habits for Successful Co-Op Runs
The store page's accessibility section lists custom volume controls, which helps if you're running voice chat alongside game audio. Beyond that, a few habits keep four-player sessions smooth:
- Call out before you grab. Two players yanking the same object can topple a section.
- Name your sections. "Lower-left is tilting" is faster than "the tower is moving."
- Pause the climb after a big upgrade. Let the runner report what ability they picked up.
- Agree on a rebuild signal. One word that means everyone stops and stabilizes.
Using Steam Achievements as Group Goals
The store page lists 44 Steam Achievements, including early progress markers like "Building Started," "10m," "Living Blocks," and "20m." Those names suggest height-based milestones, which makes them natural group targets. Chasing a height achievement together gives a session a clear finish line even if the laser run goes sideways.
