Play the Moon Rock Duckets beta.

How the beta works

1. Get the game. Download and run Setup on a Windows 10 or 11 (64-bit) PC. It installs for your Windows account and adds a Start menu entry. The desktop shortcut option is checked by default; you can untick it.
2. Claim a free Beta Key with your name and email address, then enter the verification code sent to that address. Your key is shown on screen once, so copy or save it.
3. Start the game, paste your key into the Beta Key screen and select Activate. The game remembers the key on that PC.
4. Play for 30 days from your first activation. The game checks your key online every time it starts, so you’ll need an internet connection at each launch.

Play online with Quick Match

1. Choose your world and mode in the game menu: Aerie or Ring World, and Deathmatch or Battle Royale.
2. Select Online Quick Match. The game joins an available room with the same world, mode and build. If none is available, your PC hosts a new room and waits for another player. No IP-address exchange or port forwarding is needed.
3. Wait for players to load. The countdown starts when at least two human players have joined and all admitted players are ready. Bots do not count toward that minimum. Battle Royale admission closes when the round starts.

Online rooms initially have eight player slots. One player's PC runs the match; if that host leaves, the match ends. An internet connection is required throughout online play. You can cancel an online search from the menu.

Radio is unavailable in online matches. LAN Quick Join / Same Network and Solo Practice remain separate options for nearby or solo play. The Privacy Policy explains how our relay handles the connection and game traffic.

What’s in this beta

The beta includes two worlds, Aerie and Ring World, with combat on foot and in flight. It’s pre-release software: expect bugs, missing polish and changes between builds. Experimental city maps and the exoplanet route preview are future development and are not part of this beta.

Tell us what you find with the in-game feedback form. Claiming a key means accepting the Beta Terms; the Privacy Policy explains what the beta collects and why.

Changes in 0.2.9.16

• Weapons and loadouts. Updated modular weapon models include the sniper rifle and Vesper crossbow. Choose your starting weapon and compatible components in Loadout before deployment. First-person weapons sit farther from the camera.
• Session progression. Earn EXP toward 48 gameplay unlocks: 40 components, six skills and two ducket capacitors. Components affect handling and combat statistics, including recoil, aim speed, reload speed and range. Progress lasts for the current session.
• Hold-to-view scoreboard. Hold Tab to see the in-game scoreboard; release it to hide. The tactical map now defaults to holding N. Press C to switch between first- and third-person views. Change these keys in Settings > Hotkeys.
• Crossbow wake. Vesper's shock wall now spares the shooter and allies while retaining its effects on enemies.
• Aerie improvements. The central island has one geodesic dome, more detailed grey-rock undersides and additional foliage mixed with the original trees.

Online Quick Match, LAN joining and Solo Practice retain their separate menu options. Aerie and Ring World remain the only public beta worlds.

Your existing beta features

Choose and save your public player name after activation. Verify your email when claiming or recovering a key; using the same address keeps your original access window and retained rewards. Activating a verified key records Beta Tester recognition for a future release. The badge is not displayed in this build.

Menu artwork preserves its proportions, and the beta menu includes only Aerie and Ring World.

Known limitations

Permanent ranked progression is not available. Current player-hosted matches and Solo Practice do not save EXP or unlocks to an account, and cannot award the permanent Rank 1 completion badge or the glowing [BTsTr] clan tag. The activation-based Beta Tester record described above is separate. The Loadout account-rank refresh may report that the service is unavailable.

The 40 component upgrades currently change gameplay tuning while retaining the base component appearance; they are not 40 distinct visual models. Aerie's wider landscape and foliage still need further visual polish.

Explorer's first-person sleeves can show ragged edges during whip and spear strikes.

First launches of newly signed builds have sometimes been delayed or stalled on the development computer. Wait for an existing launch before opening another copy. Clean-PC installation has not yet been verified.

Earlier public-relay gameplay checks used separate game processes on one computer, covering Aerie and Ring World in both Deathmatch and Battle Royale. Installation on a clean second computer and play between independent internet connections remain unverified. The eight-slot room limit is not a completed eight-player load test, and connection quality will vary with the host and players' distance from the relay.
