Physics Builder
An early UE4 sandbox experiment — the physics playground that inspired War Builder.
About the prototype
Physics Builder was a standalone Unreal Engine 4 prototype: a physics-based building sandbox used to explore modular construction, instant rebuilds, and destruction without loading screens. It was never released as a finished product.
The ideas from this experiment — modular build pieces, vehicle assembly, and physics-driven combat — later became War Builder: Demolition Fury, the released Android game on Google Play.
