Put Out The Sun is a simulation game built around an incremental loop of cooling a star through absurd, escalating methods. Players control four-armed aliens tasked with dimming the Sun, starting with nothing more than their own spit and progressing through layers of upgrades, automation, and resource management on PC.
Gameplay
The core loop centers on cooling patches of the star's surface. Each drop of water that lands reduces heat and generates credits that fund faster tools and larger delivery systems. Early efforts rely on manual spitting and refilling at a well, but the process quickly expands to include water guns of increasing size and power. The star itself reacts visibly as cooled spots remain dark while it rotates, providing constant feedback on progress.
Resource gathering adds depth through ice mining. Players crack chunks from a mountain with a pickaxe, haul them back to the well, and convert them into usable water. Automation enters the picture with conveyor lines that players can curve, merge, split, and route over lifts. Ice machines and launchers feed into automatic water turrets, while drones and tankers handle ongoing supply runs. The result is a steady shift from direct action to overseeing expanding production chains that keep water flowing toward the target.
Jetpacks, vehicles, and a ship extend reach to distant sections of the star that ground-based tools cannot hit. Every upgrade tier builds directly on the last, creating a clear ladder from the first spit to full coverage of the surface.
Game Modes
The game supports online co-op for one to six players. Earnings scale according to crew size, which keeps both solo runs and full-group sessions balanced in terms of progression speed. Built-in voice chat lets teammates coordinate without leaving the game. Color selection from a crew palette helps distinguish players during shared sessions.
No separate single-player or competitive modes exist beyond the adjustable co-op scaling. The focus remains on collaborative incremental progress rather than versus play or isolated campaigns.
Progression and Automation
Advancement follows a steady ladder of purchases and unlocks. Credits from cooled surface patches buy faster aiming tools, larger delivery systems, and eventually full automation setups. Conveyor networks and turret placements reduce the need for constant manual input, freeing players to focus on expansion or exploration with vehicles and the ship. A complete run from initial spit to the final darkened state lasts roughly three hours when following the upgrade path efficiently.
The systems reward experimentation with layout and timing. Efficient conveyor routing and timely drone deployment compound gains, while poor placement forces more manual intervention. The incremental nature means early choices compound into later efficiency, but the short overall run length keeps sessions focused.
Is It Worth Playing?
Put Out The Sun suits players who enjoy incremental simulation games with co-op elements and visible, escalating results. The absurd premise of cooling a star with spit and ice delivery lines provides consistent novelty, while the automation layer adds management depth without overwhelming complexity. Co-op scaling makes it accessible for groups of varying sizes, and the three-hour run time fits sessions that feel complete rather than endless.
Those seeking deep narrative, competitive multiplayer, or high-skill action mechanics will find less to engage with here. The game delivers on its described systems of resource loops, automation building, and collaborative cooling, making it a solid choice for fans of the incremental genre who want a lighthearted co-op twist on PC.
