Source basis: this guide is synthesized and rewritten from the only substantive guide that exists for the game — the Steam Community guide “100% Achievements Guide | Together: Moon Escape” by FOXIK — cross-checked against an English re-write of it on treyexgaming.com and the player comments under FOXIK's guide. Official details are from the Steam store page (app 3744430). This game has no number codes or combination locks: nearly every secret is a hidden stash you reach by spotting climbable ledges, so the honest answer is always the chapter, the landmark, and the method. For the exact ledge positions, FOXIK's annotated screenshots are linked — nothing here is invented.
What is Together: Moon Escape?
Together: Moon Escape is a handcrafted two-player co-op adventure set in low gravity, made by CarlosGameDev (published with CouchPlay Interactive) and released on April 21, 2026. You and a partner crash on the Moon and have to solve intricate asymmetric puzzles and escape “Moontella's extremely profitable slime empire” across 17 chapters, mixing puzzle-solving, platforming and parkour, and bouts of slime combat. There is no solo mode — it is true co-op, built so that many rooms only open, and many secrets only become reachable, when both players work together.
Almost none of the achievements come from the story itself. Instead they are tied to 13 hidden stashes, four slime-combat milestones, one very silly hidden character, and one developer challenge. This guide collects all 19 optional achievements, in chapter order, with the puzzle context around each one so you always know where you are when the secret appears.
How secrets work in this game (read this first)
- Most stashes sit just off the main path. They rest on top of a rock, a pillar, a beam, or a ledge that you have to climb up to. The route up is almost always a set of hidden climbable spots — little footholds on the stone or wall that are easy to walk past. In his screenshots, FOXIK marks these footholds with numbers so you can see the order to jump.
- Bring your partner. Several stashes need both of you — one of you climbs while the other follows the same line, or you both have to cross and come back. If a stash looks unreachable solo, that is the game telling you to do it as a pair.
- There are no codes to enter. If you came here looking for a keypad combination, there isn't one. The “solution” to a secret is spotting the climb and the landmark, which is why this guide leans on FOXIK's marked screenshots for the precise footholds rather than pretending exact coordinates exist.
- Nothing is permanently missable. If you reach the end and a chapter achievement didn't pop, you can start a session and replay that chapter — just make sure you are the host (this is how FOXIK and commenters recovered the Chapter 5 ones).

Chapter-by-chapter walkthrough
Chapter 1 — Damaged Ship: Hidden Among Us
The first secret shows up early, and it is easy to run straight past. After you solve the toilet puzzle and step into the next room — the one lined with shelves (the crew's quarters) — stop and look low. On the lowest shelf there is a hidden stash. Grab it for Hidden Among Us before you carry on.
Chapter 3 — Lunar Surface: Launchpad Loot
As soon as you climb out of the space rocket, look at the rocks beside the launch platform. One of them has a stash on top. Getting up is your first real taste of the game's “hidden ledge” climbing — there are footholds carved into the stone that you step up one at a time.
A commenter (Othelia) clarified the trickiest jump on this one: the step marked “2” is actually three small hops — jump to the nearest power box, then across two boxes to the right, then left onto the upper box. The next two jumps are straightforward, and for the final hop you should aim for the power box on the pillar and then pull up to the top. That nets you Launchpad Loot.
Chapter 4 — Moon Caverns: Magma Secret
Once you reach the part of the cave where a fresh set of puzzles starts, scan the room for an elevated rock. The stash sits on top of one of the stones, and you reach it the same way as before: find the marked climbable footholds and go up together. That is Magma Secret.
Chapter 5 — Contaminated Lab: Lab Loot + the four slime achievements
This is the busiest chapter for achievements. First, the stash: in the room full of slimes, a hidden box is perched on a pillar. Climb the marked ledges to reach it for Lab Loot.
Then comes the grind. The same slime room is where you earn four combat achievements, and they all share one requirement: kill 512 slimes in total. They unlock as running milestones as your count climbs:
- Unprofessional — the first kills get you started.
- Amateurs — keep going.
- Slime Masters — well into the count.
- Genocidals — the full 512, total extermination.
FOXIK calls these “probably the most suffocating achievements of all,” and he is not wrong — this is the longest single task in the game. Split the work between both players, settle in, and clear them in one sitting so you don't have to set the room up again. If you somehow finish the game without these popping, you can recover them by hosting a fresh session and replaying Chapter 5 — you must be the host for the count to stick.
Chapter 6 — Slime Hallways: Infected hallways Loot + Spaaaaaaaaaaaaaaaace
The stash here is one of the gentlest. After you go through the ventilation and land on a platform, the secret is sitting on the very next platform beside it — a short, low-stakes hop away. That is Infected hallways Loot.
The second one, Spaaaaaaaaaaaaaaaace, is the gem of the whole list — FOXIK rates it the rarest and coolest achievement in the game. It hides a little “friend from another world” who is obsessed with space. Because the surprise is the point, the original guide deliberately doesn't show the character itself, only the route to where it lives; follow that path in this chapter to trigger it.
Chapter 9 — Failed Training: Testing grounds Secret
This chapter has a puzzle where one player crosses a run of platforms to progress. For the secret, don't just push forward — once you're across, both of you go back over the platforms the same way to reach the stash on the far side. Doing the return trip together is the whole trick behind Testing grounds Secret.
Chapter 10 — Impact Crater: Toilet Treasure
After the lifting-platform puzzles, look for — of all things — a toilet with something shiny on it. A bit of light parkour up the marked footholds gets you to it for Toilet Treasure.
Note that there is also a simple progress achievement just for stepping out onto the Moon at the start of Impact Crater (effectively, starting Chapter 10). It isn't one of the “hidden” ones, but it's worth knowing it exists so you don't go hunting for a secret that isn't there.
Chapter 11 — Deep Pit: Radio Loot
During the radar / communications puzzle, head left into the dark corner of the area. The stash is tucked into the shadow there. Grab it for Radio Loot.
Chapter 12 — Fishing Depths: Midnight Find
After you open the broken doors and hop across a few stones, the instinct is to keep moving — instead, turn around and look back. The stash is sitting on a small ledge behind you. That earns Midnight Find.
Chapter 13 — Old Foundation: Forgotten Loot
FOXIK flags this as the hardest stash both to find and to reach as a pair, so take your time. The route is a small chain of co-op steps: open the gate, raise the two elevators, then go through the ventilation. That sequence drops you at Forgotten Loot. If you'd rather puzzle out the exact climb yourselves, this is the one chapter where it's genuinely satisfying to do so.
Chapter 14 — Vertical Drop: Edge Secret
A breather after the last one. The stash is on a ledge right near the cliff edge — easy to spot and easy to reach. That's Edge Secret.
Chapter 15 — Silent Wastelands: Stairway Loot
Another quick one: instead of looking ahead or up, look under the stairs in this area. The hidden treasure is sitting beneath them, giving you Stairway Loot.
Chapter 16 — Buried Base: Structural Surprise (the last stash)
The final hidden stash rewards looking up rather than forward. After you arrive in the area and clear the lifting-platform puzzle, check the beam above one of the doors on the left — the stash is perched up there. Getting onto the beam is only possible once that lifting puzzle is done. Collect it for Structural Surprise.
Chapter 16 → 17 — Will you Jack it?: the no-Slime-Scanner challenge
This is the trophy run — a developer achievement named in honor of the YouTubers Jack and Will, who beat the game without ever taking the Slime Scanner (the slime visor) at the Buried Base. To copy them:
- Start from the beginning of the Buried Base chapter. You can't grab the scanner and drop it — the run only counts if you never pick it up, so play the chapter clean from the top.
- The only item you take in Buried Base is the gun. Leave the Slime Scanner exactly where it is.
- Continue all the way to the final chapter, L.U.N.A., with one player effectively bare-handed (no scanner). There you have to kill all the slimes “blind” — without the help the scanner would normally give — and then hold down the levers to finish.
Pull that off and Will you Jack it? unlocks as you complete the game.
Tips for a clean 100% run
- Slow down at every “set-piece” moment. The secrets cluster right after a puzzle is solved — the toilet puzzle, the lifting platforms, the ventilation, the radar puzzle. When a puzzle ends, sweep the room before moving on.
- Look up, look back, look under. Three of the stashes (Structural Surprise, Midnight Find, Stairway Loot) are hidden by camera angle alone — on a beam above you, behind you, or under the stairs.
- Do the 512-slime grind in one go. It's the only tedious part; clearing all four slime achievements in a single Chapter 5 session saves you from rebuilding the encounter.
- Decide the “Will you Jack it?” run up front. Because it requires never taking the Slime Scanner from the start of Buried Base, plan it before you reach that chapter rather than discovering the rule too late.
- If something didn't pop, re-host the chapter. Progress and collectible achievements credit the host, so replay the relevant chapter as the host to mop up.
- For the exact footholds, use the marked screenshots. The climbs are visual; FOXIK's guide numbers each ledge, which is the fastest way to see the jump order without trial and error.
Frequently asked questions
Can you play Together: Moon Escape solo?
No — there is no solo mode. It is a two-player co-op game by design, and several secrets specifically need both players: one to climb or cross while the other follows the same line, or both to make a return trip. You'll need a partner.
Are any achievements permanently missable?
No. If a chapter achievement doesn't unlock, you can start a new session and replay that chapter. The catch is that you generally need to be the host for the credit to register, which is how the original guide's author and commenters recovered the Chapter 5 ones.
How many slimes do I have to kill?
512 in total, in the Chapter 5 slime room, spread across four achievements (Unprofessional, Amateurs, Slime Masters, Genocidals). It's the longest grind in the game — do it in one sitting.
What is “Will you Jack it?” and how do I get it?
It's a developer achievement for finishing the game without ever picking up the Slime Scanner at the Buried Base. Start the Buried Base chapter from the top, take only the gun, leave the scanner, and complete the final L.U.N.A. chapter killing the slimes without it before holding the levers.
Are there any number codes or combination locks?
No. Together: Moon Escape doesn't use keypad codes — the secrets are physical: hidden stashes reached by spotting climbable ledges, plus a couple of simple actions. There is no combination to memorize.
Where can I see exact pictures of each stash location?
The original Steam Community guide by FOXIK — “100% Achievements Guide | Together: Moon Escape” — includes annotated screenshots that number the climbable ledges for each stash, and you can reach the game's Steam store page for app 3744430 for official details. Those marked pictures are the quickest reference for the precise footholds described above.
