- “Pretty neat for a future sequel”
The direct answer
Sludgineers is a single-player game. Steam's own feature list confirms it: the only player-mode category on the store page is Single-player. There is no co-op mode, no online multiplayer, no LAN play, no split-screen and no hot-seat. You cannot play Sludgineers with a friend.
This comes up constantly, and it is easy to see why. Sludgineers looks like it should be co-op — a job-based cleaning game with a crew van, a big polluted map and a payout screen at the end is exactly the shape of a co-op game. Several of its closest genre neighbours are co-op. This one is not.
What the developers actually said
In the pinned Welcome to Sludgineers — Links & FAQ thread on the Steam Community hub, the developers addressed co-op directly. Their position: there is no co-op planned currently, but they flagged the idea as something that would be “pretty neat for a future sequel”.
No co-op is planned for Sludgineers at present, though the developers described the idea as something that would be pretty neat for a future sequel.— Paraphrased from the official Sludgineers Steam FAQ thread
That is about as clear as indie roadmaps get. Co-op is not being withheld for a later patch — it is not part of this game's architecture, and adding networked multiplayer to a finished single-player incremental is a rewrite, not an update. If it happens at all, it happens in a different game.
What you can share
Sludgineers does support Steam Family Sharing, so there is one meaningful way to share the purchase — just not the session.
| Feature | Supported? | What it means |
|---|---|---|
| Online co-op | No | You cannot play a job together over the internet |
| Local co-op / split-screen | No | One player, one screen, one van |
| Two-player at all | No | Sludgineers has no second-player input |
| Steam Family Sharing | Yes | Household members can play your copy on their own accounts, not at the same time as you |
| Steam Cloud | Yes | Your own saves follow you between your own machines |
| Steam Achievements | Yes | 25, earned solo |
Is Sludgineers online in any sense?
Only in the browser sense. The free itch.io build of Sludgineers is an HTML5 game you play “online” in the sense that it runs in a web browser — there is no networked play involved. If you searched for “Sludgineers online” hoping for multiplayer, the answer is no; if you were hoping to play without installing, the answer is yes, and here is how.
The paid game also does not require an internet connection to play beyond the initial Steam install and any cloud-save syncing.
If you wanted a co-op cleaning game
Sludgineers being solo-only is a real dealbreaker for some people, and it is a fair one. The cozy cleaning space does have co-op options, and the wider “job with a crew” genre has plenty. Our similar games section and its games like Sludgineers roundup cover the closest neighbours — including Moldwasher, another 2026 cozy cleaning game — and flags which support more than one player.
If what you actually wanted was the incremental half rather than the cleaning half, note that incremental games are almost universally single-player by design. The genre is built around a private compounding curve; shared progression is rare and awkward. Sludgineers being solo is the genre norm, not an omission.
