Sprocket

Sprocket is a tank design and combat game. You build tanks in a dedicated designer, then take a team of your custom vehicles into battles across a range of environments. Its design challenges span WW1, the interwar period and the early, mid and late stages of WW2.

Design your tank

Shape the hull and turret by dragging faces or edges. Larger compartments provide more internal space but require more surface area to armour, while angled shapes can deflect incoming shells. You set the thickness of each armour plate, balancing protection against the weight and space it uses.

You also design a cannon that can pierce enemy armour, making room for its ammunition and the space and force needed to rotate it. Crew members can take one or more roles; they are light but large and essential, and cramped, overworked crews perform poorly.

Build the vehicle

Exterior parts can be functional or decorative, and can indicate the placement of internal components. For example, the engine is positioned where you place exhausts and vents, and can be hit if a shell penetrates the armour in that area. A fuel port placed in front of the driver may let the fuel tank absorb a projectile and save them, though it may also ignite.

You design tracks and suspension for trench crossing, mountain climbing, speed or appearance. The powerplant designer supports engines ranging from ship engines to lawnmower engines. You choose fuel capacity and tank locations, including outside the vehicle, where tanks can be shot off.

Transmission ratios let you prioritize speed in reverse or climbing ability in first gear. A transmission on each track lets one side drive forward while the other reverses, turning the tank on the spot. Engines, transmissions and tracks work together in a full powertrain simulation.

Scenarios

Take a team of your custom tanks into battles across different environments. Designs that cost too much may leave you fighting alone. Vehicles have no hit points: they remain in the fight as long as their critical internal components function. If your vehicle is destroyed, you continue the battle controlling an ally, sometimes watching your former vehicle burn.
