Mini War Colossus Workshop: 500K Cost and 6x Builder Speed

The Colossus Workshop is the top end of Mini War’s builder chain, a limited Titan-class structure that replaces the slow human builder with a large yellow mech that drills through construction timers. It is expensive, it takes a civilian slot, and it exists for one reason: cutting the multi-hour build times that late-game factories and housing pile onto your queue.

Quick answer: Place the Colossus Workshop for 500,000 cash, then place any building — its robotic builder works six times as fast as a normal builder, turning a 35-hour timer into under three hours.

Colossus Workshop stats and cost in Mini War

The building’s info card lists everything that matters before you commit the cash. It is tagged as a limited item, and its rarity band is Titan, which sits above the standard shop tiers used by ordinary Special buildings.

Stat	Value
Rarity	Titan (limited)
Cost	500K cash
Civilians required	1
Civilian density	0.01 Civilians/Stud
Effect	Deploys a robotic builder that works six times as fast as normal builders

Like every workshop variant, it adds one builder to your roster rather than boosting the builders you already have. Owning two Colossus Workshops gives you two Titan-speed mechs working in parallel, which is why the item stacks in your inventory as a counted entry.

Builder speed ladder: Workshop, Upgraded, Titan, Colossus

Mini War runs four workshop tiers, and each one spawns a visually distinct builder unit. The base Workshop sends out a human builder. The upgraded versions send out robots that get physically larger as the multiplier climbs — the Colossus mech towers over high-rise buildings when parked next to them.

Workshop	Builder speed	Notes
Workshop	Normal (1x)	Rare, $10K or 39 Robux from the Special tab
Upgraded Workshop	2x	Sold in the Black Market for 1K gems
Titan Workshop	4x	Robotic builder, larger unit
Colossus Workshop	6x	Titan rarity, 500K cash, limited

The Black Market only accepts gems and rotates its stock, so the gem-priced workshops are not always on the shelf. It appears near your shop as a limited-time merchant, alongside items like the Construction Yard at 2.5K gems.

How to use the Colossus Workshop and confirm the 6x speed

Open your Items inventory, select the Colossus Workshop, and place it on your plot. It has to finish its own construction first, so give it a couple of minutes before you expect the mech to appear.

Keep it inside your country rather than tucked in a far corner. A tidy row of workshops makes it easier to see which builders are idle, and you can use Destroy Mode to read any building’s description if you need to double-check what you placed.

Place a genuinely large structure to see the difference. Small buildings such as a Gem Mine finish almost instantly and tell you nothing — pick something with a multi-hour timer, like a high-tier factory or housing block.

Watch for the builder to leave the workshop door. The Colossus unit is the yellow drill mech, and it is unmistakable next to a standard human builder or the small yellow-and-purple upgraded robot.

Verify the reduction using the instant-build prompt. Tap the building under construction to open the Robux and item menu, which displays the remaining time it would skip. A structure that starts at a 35-hour timer reads INSTANT BUILD <3H once the Colossus builder is on the job.

That prompt is the cleanest confirmation available, since it always reflects the current remaining time rather than the building’s base timer. You do not have to spend the Robux — reading the number is enough.

When the Colossus Workshop does not speed anything up

The mech is a single builder, not a global buff. If it is already assigned to another structure, your new placement waits in the queue at whatever speed the next free builder runs at, which is why players who own a Colossus still keep lower-tier workshops around.

Space is the other limit. Workshops take up plot area that could hold factories or housing, and every extra one still costs a civilian slot. Past a handful of builders, most bases run out of room before they run out of things to build.

Note: server-wide construction bonuses and the 2x Building gamepass apply on top of builder speed, so a timer you measured during a double building speed window will not match what you see on a normal server.

At 500K, the Colossus Workshop is a mid-to-late game purchase rather than an opening move — a first Workshop for $10K still does more for a new country than anything else on the Special tab. Its value shows up once your build queue is full of billion-dollar factories that would otherwise sit under a day-long timer, at which point six-times speed is the difference between logging off mid-build and finishing before you leave.
