Ore Factory Squad Co-op Multiplayer Guide
Host and play Ore Factory Squad four-player co-op: roles, voice chat, shared progression, and squad tips for Steam multiplayer sessions.
Four-Player Co-op Overview
Ore Factory Squad supports up to four players in online cooperative multiplayer on Steam. Everyone joins the host world, shares property progress, warehouse storage, and contract queue, and collaborates on mining, building, and deliveries. The game is designed around squad play — solo works, but parallel tasks shine with four roles filled.
Released July 16, 2026, with ongoing patches, co-op received a major quality boost in demo v1.7.0 with integrated voice chat. Squads can coordinate dynamite, lift timing, and contract handoffs without Discord unless they prefer external apps. Invite friends through Steam; ensure all clients update together after patches.
Watch the co-op video embedded on this page for visual squad flow, then read how to play for loop fundamentals and controls for binding customization per player.
Hosting, Joining, and Save Rules
Host creates or loads a world from the main menu co-op tab. Friends accept Steam invites or browse friends' games. The host machine runs simulation authority — lag usually affects the host least, so give build-heavy duties to lower-latency players when possible.
Progress saves on the host file. Guests do not carry separate deed unlocks back to solo saves unless the game explicitly supports cross-save migration — treat co-op worlds as shared squad campaigns. Backup saves before major property sales or factory demolitions.
Session length: agree stop points at contract completions or lift upgrades so no one loses mid-delivery inventory awkwardly. Ore Factory Squad sessions can run long when automation hums — schedule breaks at warehouse turn-ins.
Recommended Role Split
Miner: focuses underground with pickaxe, jackhammer, and dynamite; maintains ore faces and lift bins. Builder: handles conveyors, smelters, and Modular Mining Lift modules on surface and shaft landings. Logistician: runs forklifts and trucks, stages warehouse robots, monitors bins. Foreman: tracks contract timers, accepts jobs, calls voice updates.
Rotate roles hourly to reduce fatigue — mining exclusively for three hours burns out even dedicated diggers. Rotations also teach troubleshooting: builders who never mine underestimate shaft travel time; miners who never build place belts inefficiently.
Vehicle controls differ from on-foot — see vehicle controls before assigning a new driver mid-session.

Voice Chat, Text Chat, and Communication
Demo v1.7.0 added in-game voice chat with push-to-talk and volume sliders per player. v1.0.5 added text chat as a secondary channel — useful when USB headsets fail, stream overlays mute voice, or squads need written confirmations during belt rework. Configure input devices in audio settings before joining public friends-only lobbies.
Callouts that matter on voice: dynamite countdown, lift ascending with full load, contract five-minute warning, and factory pause during smart filter reconfiguration. Text chat works for quieter callouts like "accepting Gold contract" or sharing 10-digit lobby codes after v1.0.5 restored protected codes.
Miscommunication causes more co-op failures than difficulty — two players accepting conflicting Gold and Iron megacontracts without split smelter rows stalls both. For achievement hunting, see achievement tips for squad routing without duplicate effort.
Roles, Permissions, and Lobby Security (v1.0.5)
v1.0.5 introduced a Role & Permission System managed through the computer app. Default Employee role limits destructive actions for strangers in public lobbies — hosts should configure custom roles before opening browse so trusted friends can build while guests haul or drive. Full detail on roles and permissions guide.
July 2026 security hotfixes (v1.0.3 and v1.0.4) temporarily disabled lobby codes and hid invite-only rooms; v1.0.5 rebuilt lobby security with multi-step authentication, restored 10-digit lobby codes with protected handshake, re-enabled Steam friend join, and made invite-only rooms visible again in the Server Browser. Read v1.0.5 patch notes before returning to public hosting.
Public lobby hosts: combine restrictive default Employee permissions with text chat for moderation. Invite-only squads can grant broader builder roles without exposing factories to griefers. Smart filter ownership etiquette — agree who may edit Splitter Belt rules — is covered in smart filters guide.
Scaling Co-op from Demo to Full Release
The demo supports co-op for early levels — perfect for friend group trials before purchase. Demo co-op teaches join flow and shared mining but omits late vehicles, multi-property logistics, and full achievement sets.
Full release co-op adds warehouse robots, larger deeds, smart belt filters, role management, Lunchbox buff planning, and truck convoys between properties. Mid-game squads split across surface and underground simultaneously — voice or text chat becomes essential when players are not in visual range.
