Sprocket (v0.2.55.5)

Armour geometry, internal volume, gun recoil, and raw engine power all matter in this focused tank-building simulation. Sprocket puts you in the role of an armoured vehicle designer working through the technological leaps from World War I to the final years of World War II. Its mood is less about cinematic battlefield spectacle and more about the quiet satisfaction of turning a sketchy idea into a functional steel machine. Every successful design feels earned because the same compromises that shaped real tanks—protection, mobility, firepower, and space—constantly pull against one another.

The central loop revolves around building a hull and turret piece by piece, then testing whether your creation can actually survive and fight. Players manipulate faces and edges to shape the vehicle, adjust the thickness and angle of individual armour plates, arrange internal compartments, and fit a gun that has enough room to traverse, recoil, and carry ammunition. A low, sharply sloped hull may deflect shells effectively, but it also limits crew and component space; piling on thick armour improves protection while making the tank slower and heavier. Progression through historical eras changes the design problems and available expectations, encouraging you to rethink layouts rather than simply build one overpowered vehicle. The approachable editor makes basic prototypes easy to assemble, while efficient late-war designs demand careful attention to every millimetre.

What separates Sprocket from broader military sandboxes is its devotion to the engineering logic behind armoured warfare. Rather than treating tank stats as abstract numbers, it makes shape, volume, weight distribution, and ballistic angles part of the creative process. The clean interface supports experimentation, so failed concepts are usually valuable lessons instead of wasted time, and the open-ended construction offers strong replay value for tinkerers. Fans of Besiege, Trailmakers, or detailed vehicle builders who want a more grounded, historically flavoured challenge should feel at home, while newcomers can start with simple designs before chasing authentic-looking machines.
