Ultimate Mining Tycoon Co-op and Multiplayer Guide

Ultimate Mining Tycoon is an online co-op Roblox tycoon by Innovation Inc. (madattak and Rolijok, place ID 18680867089, v0.5.13). Up to eight players share The Mine and hub shops, but each owns a private 30×30 plot with its own factory, vehicles, and cash. Understanding what is shared versus personal prevents frustration — especially when a friend cannot unload at your Ore Unloader or your haul vanishes after a disconnect.

Start with Getting Started if you are new. For shop locations and recovery buildings, see Locations and Shops.

What is shared vs private

Shared (server-wide)	Private (per player)
The Mine tunnels and collapse timer	Plot factory and Build Shop machines
Mine regeneration every 100 minutes	Cash balance and pickaxe inventory
Hub roads and shop NPCs	Vehicle spawner and active vehicle
Collapse Robux extension (+30 min / 225 Robux)	Prestige progress and Medals
Chat and horn signals	Ore Unloader on your plot only

There are no promo codes and no cross-plot trading UI — “co-op” means coordinated mining and social blasting, not shared factories.

Plot ownership rules

When you join a server, you claim one of eight plots. That plot is yours until you leave.

Critical ownership facts:

• Only you can place, move, or delete machines on your plot.
• Only you can dump ore at your Ore Unloader — friends cannot feed your factory to help process their haul.
• Only one vehicle per player at a time from your spawner.
• Neighbors can see your factory but cannot interact with it.
• Building into visual overlap with another plot is poor form; keep belts inside your 30×30 boundary.

If a friend says “unload at my base,” that is impossible by design. They can mine ore you both benefit from in shared tunnels, but each player hauls to their own unloader.

Shared mine etiquette

The Mine belongs to everyone. Good co-op behavior keeps lobbies friendly:

Tunnel and ramp access

• Leave vehicle-width ramps when blasting — seal a Super Crawler route and the whole server suffers.
• Do not trap players in blast chambers with fresh C4.
• Warn before Nuke placements (Robux tier with server-wide chat announcement).
• Park vehicles off the main descent path — a parked Exa-Drill blocking a choke point causes horn wars.

Ore and depth courtesy

• The mine is not “first pickaxe wins forever” — rotate depth zones if six players farm the same Titanium wall.
• Avoid blasting high-value ore clusters your party is actively mining.
• Pick up ores you mine; leaving surface Tin piles is harmless, but blocking gem veins annoys jewelcrafting players.

Full blasting rules: Explosives and Obsidian. Depth tables: Mine Layers and Ores.

Co-op mining strategies

Coordinated groups clear depth faster than solo players, but only if roles are split.

Role split that works

Role	Player A	Player B	Player C
Blast	C4 ramps to target depth	Support seal / Obsidian	Buy dynamite restocks
Haul	Super Crawler full loads	Second hauler at other depth	Factory runner stays on plot
Process	Own factory — cannot cross-feed	Own factory	Own factory

Factory runner stays on plot to verify belts clear while haulers mine — idle machines during group runs waste the advantage.

Friend servers vs public lobbies

Friend-only servers (Roblox privacy settings) let you:

• Sync collapse timer planning without random blast grief.
• Voice chat depth targets without horn Morse code.
• Share Scripts automation knowledge safely — still against Roblox ToS if exploitative; this wiki documents gameplay, not cheats.

Public lobbies suit solo-minded players who want live economy energy. Expect random collapse extensions and unannounced nukes — carry patience and Controls horn binds.

Depth stacking

Assign layers: Player 1 farms Bedrock Titanium, Player 2 pushes Crystal Depths gems, Player 3 preps Underworld with explosives. Shared tunnels still merge visually, but split targets reduce competition on one ore color.

Vehicle coordination: Vehicle Logistics.

Ore Recovery after disconnect

Multiplayer disconnects happen — Wi-Fi drops, Roblox updates, mobile battery. Ultimate Mining Tycoon saves most inventory, but factory edge cases route items to recovery buildings.

After reconnecting:

1. Check Automatic Ore Recovery (8 bays on the secondary hub road).
2. Visit the Ore Recovery Centre (manual reclaim, 2,000 ore storage cap).
3. Inspect your vehicle and backpack — ores in vehicles generally persist.
4. If unloader contents glitched on load, see v0.5.5–v0.5.12 factory save notes on Updates Hub.

Recovery is per-player. A friend’s disconnect does not put their ore in your recovery bay.

What persists vs what prestige wipes

Co-op players often ask what survives a group member prestiging while they continue.

Persists across sessions	Resets on prestige (individual)
Medals and Rolijok upgrades	Cash
Prestige machines (Ore Upgrader, etc.)	Standard factory machines
XXL Robux backpack (64 slots)	Cash-tier backpacks
Vehicle Power upgrade levels	Pickaxes and cash explosives
Friend’s plot — unaffected by your reset	Your vehicles from spawner

Your prestige does not reset friends’ plots or Medals. Their mine tunnels also stay until the 100-minute collapse.

Prestige math: Prestige and Medals.

Communication tips

Roblox text chat is slow for mining coordination. Practical signals:

• Horn — “I am hauling up” or “clear the ramp” (Controls).
• Depth callouts — “800m Titanium wall east” beats silent competition.
• Collapse timer — announce at 15 and 5 minutes so nobody loses a half-full Super Crawler underground.
• Discord — Innovation Inc. Official Links for patch coordination outside the game.

Avoid spamming global chat with trade requests — there is no trade system.

When solo beats group play

Co-op is not always optimal:

Situation	Solo advantage
Factory tuning / belt debugging	Zero blast interference
Prestige cash banking toward $80M	No competition for shared ore walls
Learning Factory Layout	Quiet plot to delete mistakes
Vehicle unloader stress tests	Controlled dump timing

Situation	Group advantage
Opening Underworld ramps	Combined C4 clears Obsidian faster
First time reaching new depth	Someone else’s ramp saves dynamite
Social progression	Motivation during mid-game grind

Many endgame players alternate: solo factory nights, group blast weekends.

Multiplayer and scripts

Some lobbies run automation scripts from third-party sites. Innovation Inc. designs around active mining — scripts may violate Roblox Terms of Use and risk bans. This wiki’s Scripts page summarizes community tools for awareness, not endorsement. Co-op etiquette still applies: scripts that lag the server harm everyone.

Co-op Ultimate Mining Tycoon means shared holes and private paychecks — blast together, sell on your own plot, and reclaim your ore when Wi-Fi betray you.
