Co-op is here!
Co-op multiplayer is playable right now in open beta. The update releases on August 13, 2026.
We're closely monitoring feedback on our discord, so be sure to head over there to join the discussion.
IMPORTANT: If you play on mobile as well, then you will be locked out on the mobile version if you join this beta (because that build will be behind your steam build). You can easily get around this by emailing us at [email protected], and we can get you access to the matching mobile beta build.

Changelog
New Cooperative Multiplayer
- You can now play with another player in campaign games, missions, and sandbox game modes
- Missions can now be flagged as supporting co-op, single-player, or both

New biomes
- Blockmen City (protect the citizens during enemy attacks)
- Goblock Slum (random surprise attacks when entering Goblock huts)
- Zomblock Tombs (Blockmen soldiers turn into Zomblocks on death and sometimes when damaged by a Zomblock)
- Blockbot Grid (blocks touching the grid are unpowered, and Power Generators built anywhere over the grid don't work)
- Blockoid Temple (must build barracks at center of temple, and you can't build blocks with weapons on temple roads)
New turret blocks
- Howitzer - a powerful turret with unlimited range that can't shoot flying targets
- Neutrino Gun - a short-range energy turret that shoots through blocks
New enemies
- Goblock Copter - flying units that drop bombs on targets below
- Goblock Lobber - units with mortars strapped to their backs
- Zomblock Swarm and Swarmlets - a flying mass that releases Swarmlets over time and as it takes damage
- Zomblock Tumbler - a rolling bomb that poisons an area on impact
- Zomblock Necro - drops an artifact when killed that, until collected, creates a rift spawning more and more Zomblocks over time
- Blockbot Vector - a close-combat Blockbot unit with blades for arms
- Blockbot Converter - slowly converts the map into areas of the Blockbot grid, destroying existing blocks where converted
- Blockbot Hacker - can't be attacked by turrets, and until it is destroyed, reprograms nearby turrets to the Blockbot team
- Blockoid Knight - a close-combat Blockoid soldier with a special shield that blocks all damage from the direction of the last incoming attack
- Blockoid Relay - teleports Blockoid warriors away from battle when they lose their shields, and restores some of their shield HP
New co-op missions
- Bash Brothers
- Twin Pistons
Balance
- Global mods are now cheaper to craft in the premium game version. They are cheaper to unlock, and the upgrades scale up in cost as the rarity increases.
- Blockoid Spirit Walker shield hp reduced from 250 to 200
- Hellfire turret damage per missile increased from 2 to 4
Missions and Sandbox Modes
- You can now choose which equipment, blocks, and troops are available to equip when building a mission, along with setting their default levels
- You can now set the level of individual blocks already built in sandbox and mission builder modes
- You can now set a player respawn time and option to respawn at their starting position in mission and sandbox settings
- You can now assign variants to enemy Blockmen (e.g. sergeants, medics, and scouts)
- Added a new commander action that allows you to change some of the attack settings (time of day, weather, music, etc.)
- Added a new commander action that activates a random action with the same color. Also added a new "wait" activation trigger for actions that will be triggered by this new action.
- Commander actions increased from 100 to 200
- You can now set item levels in sandbox mode
- Added gold and ore to the list of items that can be placed in the world
- Item blocks also remember the last type placed so you can repeat placing the same item (in the same way as when placing NPCs)
- Goblock Blimps are available to build in sandbox modes again
- Made more decorative blocks from your command ship available in other sandbox modes
- Added a new "Copy" block option that allows you to temporarily copy most block types from the world into your building loadout (allowing you to build identical blocks to those found in special biomes, even if you don't have that block in your inventory)
- Added the Zomblock Necro Orb as a placeable item in missions / sandbox
- Enemy Blockmen now have a different faction logo and their own barracks
Miscellaneous
- You can now bind your equipment slots to the mouse wheel. To do this, first unbind the mouse wheel from the default “Build Menu” binding. Then, bind “mouse wheel up” to “Next Slot”, and “mouse wheel down” to “Prev Slot” (or vice versa). You can also now adjust the mouse wheel sensitivity and mode in the controls section of the options screen, which affects this behavior.
- You can now keybind directly to the multiplayer pings, emotes, and all messages radial menus
- The combat training mod now applies damage bonuses to troops with secondary weapons
- Detection Dart now also allows attacks to hit affected targets in the dark without missing
- When clearing a keybind that has both mouse and keyboard bound, you now get a choice of which to clear instead of automatically clearing both
- Tweaked the first-person camera to be more centered relative to your body. Additionally, you now slide around corners when moving against them, allowing you to fit more easily through small openings without getting hung up on the edges
- Shield Bot now correctly protects against the solar storm hazard
- Goblock Hammerers now attack units in modes without an HQ for them to target or if they are set to "Attack" AI in missions
- Zomblock Talons added to attacks in campaign mode

- Jump Pack now only activates on your second jump or when you are already falling
- Target Light blocks have been renamed to Auto-Spotlights
- You can now move the camera around the world when taking a screenshot
- Added a sound and screen effect when you take a lot of damage over a short period of time
- Your profile name now stays in-sync with your corresponding game network display name
Bug Fixes

- Fixed a bug where refunds were not being given for blocks deleted in single-player campaign mode
- Fixed a bug where the camera would clip into ceiling blocks when flying in first-person view

- Fixed a bug where sometimes equipment sounds would continue to play after you died
- Fixed issues with right click to aim when using the track pad, or when “aim lock” was enabled

- Fixed a bug that could cause hotkeys to be set incorrectly when picking up and dropping equipment items over time
- Fixed a bug where removing a mine or drill block in campaign mode after it had been moved in the world wouldn't restore the ore deposit. Note this fix only affects new games/saves. If you load a game and delete a mining block that has been moved from its original position, the ore deposit will not be restored.
- Fixed a bug where enemies sometimes wouldn't attack their targets

- Potentially fixed a bug where the environment wouldn't render when "Soft Shadows" was set to "low" (only affected certain computers)
- Crash fixes
