About Sprocket
Design and build tanks from scratch with intuitive shape and component editors, then test them in realistic combat where armor angles matter, internals can be destroyed independently, and your design choices directly impact performance. It's a deep simulation that rewards understanding tank design principles across different eras, but newcomers without tank knowledge may want to wait for better tutorials.
Please note: There is currently no dedicated tutorial. If you don't enjoy figuring things out or you don't know much about tanks, it may be worth holding off until better guidance is in place.
Hull & Turret Shape Design
Easy to use and flexible enough to give you endless design starting points. Drag on a face or edge to move it. Bigger compartments create more internal space but have more surface to armour.
Well angled shapes may bounce incoming shells off entirely, leaving only a scratch and several ringing ears.Armour Design
Set the thickness of each armour plate, allowing you to block shots from your foes. Though the weight and space used adds up!
Cannon Design
Build a gun capable of piercing enemy armour. You'll need enough space and force to rotate it. Make sure you save enough room for ammo!

Crew Design
Humans are light but large and quite essential, squeeze them in and assign them one or more roles. Cramped and overworked crew perform poorly.
Attached Parts
Add functional and decorative parts to the exterior of your vehicle. These can define where internals are e.g. the engine is positioned where you place your exhausts and vents, then gets hit if a shell pierces your armour in that area. Place a fuel port in front of the driver and the fuel tank just might absorb a projectile, saving their life - if it doesn't ignite...
Track Design
Focus your tracks and suspension on trench crossing, mountain climbing, going fast or just looking cool.

Engine Design
Design anything from ship engines to lawnmower engines in a basic powerplant designer.
Fuel Tank Design
Set your fuel capacity and tank locations. Even bring them outside of the vehicle - if you don't mind them being shot off every now and then.
Transmission Design
Design your ratios - make it faster backwards than forwards or give it a 1st gear that can climb any mountain. One of these on each track will let one side drive while the other reverses, turning on the spot.
Internal Component Health
No hit-points. Vehicles carry on the fight as long as their critical internals are still functioning.
Full Powertrain Simulation
Engines, transmissions & tracks work together to move your tank with a realistic simulation, making vehicles feel like the real thing.
Scenarios
Battle in a range of environments with a team of your custom tanks, although make your design too expensive and you might be on your own. If your vehicle is destroyed, you carry on the fight in control of an ally - sometimes watching your previous self go up in flames.

This game is awesome, I made a tank with a 250mm cannon that rolls backward when it fires, 10/10 will buy again if possible1 found this helpful
ver fun
the game is great I made tanks from 1918 all the way to 2026 like the Abrams. I wish there where more stuff to do though, like a auto cannon and working mgs. I would also like missles to and radar. Also the commanders stuff like hatch ,viewing port and others don't work, it says that you cant to 2 jobs for the commander but i'm only doing one so now I cant use anything related to the commander.
manliest military game
very good tank making game, has limits, but are fairly hard to get to even if you are creative, made a tank with a upside down turret and it works without issue, also runs amazingly
not worth the price at all. little freedom of actual creation.
