Dumpster Gang supports one to four players, all online. The publisher describes it as a co-op sandbox for 1-4 players, and every store listing repeats that number.
Four is the maximum. There is no fifth slot, no spectator mode that turns into a player, and no announced way to raise the limit.
Why four, and not eight
The cap follows the mission design rather than the network. A job has a finite list of objectives, a finite amount of loot and a single Exterminator. Four raccoons already saturate a room: two hauling, one making noise, one covering the route.
Adding four more would not make the job harder in an interesting way. It would make the Exterminator irrelevant, because eight raccoons can absorb a capture and keep working, and it would turn the loot carrying into a conveyor belt.
Four is also the number that keeps a session readable. In a physics sandbox where every object can be thrown, eight players in one kitchen is a performance problem before it is a design problem.
What solo actually plays like
Solo is fully supported, and the game does not hide content behind co-op. The same jobs exist, the same Exterminator patrols, and the same loot has to reach the burrow.
What changes is the workload. With one raccoon, every noise is yours, every carry is yours, and a capture ends the run rather than starting a rescue. The result is a slower, more careful version of the same game, closer to a stealth sandbox than the four-player comedy.
If your group has five
One person sits out, and the practical answer is to rotate.
- Rotate by job. The demo has three areas, so a group of five can swap one player per area and everyone plays two of three.
- Rotate by session. Full game sessions are longer, so alternating nights is less disruptive than alternating mid-job.
- Do not split into 2 and 3 permanently. The game is tuned for a small gang, and a three-player job is a very different experience from a two-player one.
What four players actually look like in a job
Four is enough to specialise, and specialising is where the game opens up.
A typical clean run splits into four jobs: one raccoon clears the route and finds the vents, one handles the loud objectives that pull the patrol, one carries the heavy loot to the burrow, and one floats — helping with carries, covering the rescue, watching the patrol.
With three players, the float disappears and the route-finder also carries. With two, every raccoon does two jobs and the noise budget doubles. Solo, all four roles land on one animal.
That progression is why the cap is four rather than a technical limit. Every slot below four removes a role; every slot above four would add a spectator.
Why a fifth player breaks the rescue
The cage is the mechanic that punishes extra players least and rewards them most — until it does not. With five, a rescue can leave three raccoons working while one goes to open the cage. The job continues almost unchanged, and the capture stops being a setback.
That is the design reason for the cap: at four, a capture costs a quarter of the gang and a chunk of the timer. At five it starts costing nothing.
The mod question
There is no mod that raises the player cap, because there is no mod ecosystem yet. Dumpster Gang ships in December 2026, and nothing has been announced about official mod tools, Steam Workshop support or a server browser.
Searches for a four-player-limit mod come from people who want a fifth friend in the lobby. Until the game is out and has a modding scene, that mod does not exist, and any download claiming to be one is worth avoiding.
Player count in the demo
The demo supports the same one to four players as the full game, online. It is the cheapest way to test whether four is the right number for your group: run a full gang through the farm, then run the same area with two, and the difference in pressure is obvious.
No local players
All four slots are online. The game has no split screen and no local co-op, so four players means four machines and four copies.
Solo is not a lesser version of the game
It is tempting to treat one player as the mode you use to practise. The design does not support that reading: every job exists, every objective stands, and the Exterminator patrols the same route he would with four raccoons in the level.
What solo removes is the recovery margin. A capture with four players is a rescue; a capture alone is the end of the run. That single difference makes solo a game about not being seen, while four-player is a game about managing the mess after you are.
Both are supported. Neither is the tutorial for the other.
The short answer
One to four players, online, no exceptions. Solo is supported, five is not, and there is no mod or setting that changes it. For a group of five, plan to rotate.
