Sprocket
Early access since Aug 2021
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.

Evaluation
Sprocket is a tank design and combat game actively in Steam Early Access, developed primarily by Hamish Dunn (with a second developer, Mark, now contributing). The game has been in continuous, high-cadence development since its Early Access launch on August 26, 2021.
The most recent major milestone was a complete vehicle movement overhaul (version 0.2.51.36), which shipped to the stable branch on June 18, 2026, after four months of development. This overhauled track physics, powertrain simulation, suspension behavior, and driver logic — described by Hamish as "a pretty foundational update which opens a lot of doors for other areas like weight dispersion, in-depth engines and more steering systems." Two further feature patches followed in July 2026: dynamic centre-of-mass simulation and a transmission editing interface (July 7), and new armour overlay modes (July 28), confirming the developer remains actively working on the game.
Before the movement overhaul, version 0.2.50.10 (February 23, 2026) introduced a new cost system and a major transmission realism pass. The landmark version 0.2 stable release — representing 30 months of interior physics and design system rewrites — shipped on November 4, 2025.
On November 5, 2025, the developer published Roadmap Update #3, outlining a substantial pipeline of future features: a GUI overhaul, improved sandbox spawning, deep mod support, Steam Workshop, an original soundtrack, small-scale multiplayer, machine guns and autoloaders, infantry simulation, a shell designer, anti-aircraft systems, oscillating turrets, quad tracks, wheeled vehicles, and tutorials. This roadmap makes clear that the game is nowhere near the end of its planned development.
The developer has maintained a sustained cadence of major updates (two counted in the scanned period, with the prior evaluation noting a third), feature patches, and bug fixes throughout 2025 and 2026, with the most recent developer communication on July 28, 2026. There is no indication of an impending 1.0 release or conclusion of Early Access.
Evidence
Feature patch 0.2.53.2 adds new armour overlay modes and UI improvements, with Hamish noting he is focused on a UI rework. Most recent developer communication.
Feature patch 0.2.52.3 adds dynamic centre of mass, basic transmission editing, reworked visual and audio effects, and several AI and physics improvements.

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.
Well angled shapes may bounce incoming shells off entirely, leaving only a scratch and several ringing ears.

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.Are these done yet?
