Brotato Co-op Mod in TrainerHub Files — Works with Primal Dread DLC, 2-4 Players Online

People search “Brotato co-op mod”, “brotato online multiplayer”, “how to play Brotato with a friend online” because the official co-op is local only: up to 4 potatoes on one PC, controllers or a shared keyboard. Out of the box you cannot play Brotato over the internet. Here is what actually works in November 2026, after Primal Dread and the free 1.2 patch.

Primal Dread and co-op — it works. The second paid DLC launched on 2 November 2026 ($3.99, Steam / Epic / GOG): a jungle map with 20 waves of new enemies, elites and bosses, 10 characters, 17 weapons, 40 items, 3 pets and the new Evolution stat — the Mecha path (weapon stats, laser mecha dinosaurs, oil puddles) or Mutation (item copies, acid-spitting mutants). Steam lists the DLC as Shared/Split Screen Co-op, so local co-op on the new map works right away. The BrotatoOnline author shipped a 1.2 fix within the first day, so online jungle runs come together too.

Option 1 — BrotatoOnline (six666): Steam P2P + LAN. The most active online mod: friend lobbies and public lobbies, and “Continue Game” after a disconnect — everyone returns to the menu, the host clicks Continue, the rest rejoin. Subscribe on the Steam Workshop → six666-BrotatoOnline. Every player enables the mod, same mod version for everyone. In the main menu settings set “When Focus Is Lost” to “Do Nothing”, otherwise Alt+Tab breaks sync. One input device per PC online. Characters and weapons follow the host’s unlocks — host yourself to use your own; your save is not touched.

Option 2 — Brotato Online 0.2.10 [Alpha], 2–4 players. Online button in the main menu or F6 → Create room → invite through the Steam overlay or share the room code. The highlight is Local + online: two players on the host PC (keyboard + controller, two controllers or a shared keyboard) plus two friends over the network. Workshop page. Joining a run in progress and reconnecting are not supported yet.

Option 3 — Steam Remote Play Together, no mods. The host starts normal local co-op, the friend joins through Steam and controls the second slot. The friend does not need the game or the DLC — everything runs on the host PC, Primal Dread included. Downside: video stream latency.

Friend has no DLC? Online mods want the same DLC set on every PC. For BrotatoOnline the author says it plainly: the player without the DLC hosts. Patch 1.2 also adds the Item Set menu on character select — it toggles content from each DLC and update, so the whole group can play pure vanilla.

Mod will not start after 1.2. Disable other mods — the DLC breaks the ones that are not updated yet. Re-subscribe, update Steam (Help → About Steam: you need SteamClient023). Connection quality with a friend: Steam → Library → Ctrl+\.

8 players on one PC. For a big group there is Eight Player Coop — local co-op for up to 8 potatoes; from the 5th player the UI switches to a 5–8 seat layout, materials are shared.
