Carefully balance mobility, firepower and armour in a dedicated tank designer. Then uncarefully put them to the test in a series of combat scenarios progressing through the ages of the tank. Here, your limit is what you can fit inside your hull and turret while still being able to move forwards.

Early Access Game

Get instant access and start playing; get involved with this game as it develops.

Note: This Early Access game is not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

What the developers have to say:

Why Early Access?

“The remaining areas will all benefit from community direction.
Sprocket is single developer's passion project. Progress is swift and consistent but the project is ambitious.
The tank designer's fundamentals are all in place, allowing the core experience.”

Approximately how long will this game be in Early Access?

“About 24 months. For perspective, Sprocket will have been in development for 15 months as of August 2021.”

How is the full version planned to differ from the Early Access version?

“The full version will expand the tank designer with many more parts, design options & challenges with many more scenarios to test your designs.
Scenarios will be tied together with overall resource and vehicle management.
All of this coupled with dedicated mod support, cooperative multiplayer and a small player versus player mode (no matchmaking).”

What is the current state of the Early Access version?

“Tanks can have all major areas designed and tested in over 7 semi-randomly generated combat scenarios featuring enemy tanks, anti-tank guns, anti-tank mines, artillery with basic natural and manmade hazards.

Fair warnings

  • Limited guidance - There are currently no detailed tutorials to help you get started, help will be available on the forums.
  • Measurement system - Sprocket uses primarily metric, a few options for imperial are supported.
  • Scenario content - There's a small fraction of the total number of scenarios planned. If you're more interested in tank combat than tank designing it may be worth waiting for full release. The scenarios are quite replayable with randomised spawn points and enemy types. Different designs and playstyles will lead to vastly different experiences.
  • Bugs/glitches - Due to the huge number of possibilities, vehicles at the extremes may see odd/unrealistic behaviour (mainly with physics and AI responsiveness).
  • Saved vehicles - Vehicle save backward compatibility is not often a problem but can't be guaranteed. Fortunately you would likely only lose individual parts of the vehicle.
  • Placeholder sound and visual effects - Some effects may not be up to standards during EA.

Will the game be priced differently during and after Early Access?

“The price will increase up to full release as the value increases.”

How are you planning on involving the Community in your development process?

“Opening the doors to game suggestions with polls for new vehicle parts and scenarios.
Find the developer on the official discord server (shouldn't be hard) and have a chat.
Support/feedback all very welcome and encouraged on the Steam forums, the Discord server's relevant channels as well as Twitter: @SprocketTheGame and email:”

About This Game

Design tanks in a dedicated and intuitive designer, allowing the realistic armour mechanics that make tank combat so unique. Explore tank design's challenges through WW1, the interwar period and the early, mid and late stages of WW2.

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.


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.
