Siege Foundry is headed to iOS, bringing a tactical builder experience that focuses on the structural integrity of your custom war machines. Unlike traditional vehicle builders, this title introduces a collapse mechanic where individual floors hold separate health pools.
Tactical Construction and Combat
Players build siege machines by selecting a chassis and stacking up to five armoured floors. Each level of the machine can be equipped with different armaments, including rams, saws, hammers, ballistas, cannons, and rockets. Because each floor tracks its own health, the structural stability of your machine is a core part of the combat. If a bottom floor is destroyed, the entire structure above it collapses, which can force you to finish a level with a heavily damaged or ineffective loadout.

The campaign consists of 30 levels, with difficulty increasing through denser enemy waves and specific boss patterns. As you progress, you can upgrade your machine, which is reflected visually through reinforced components and new parts. While the game prioritizes functional, utilitarian design over spectacle, the core loop centers on managing machine damage across multiple tiers of construction.
