Siege Foundry turns a five-storey war machine into a mobile strategy puzzle

Siege Foundry is preparing to launch on iOS with an unusual tactical concept built around constructing a moving siege machine floor by floor. Players can stack up to five levels on the vehicle, with each floor containing different weapons or functions. The important twist is that every level has its own health, so damage can cause sections of the machine to collapse independently during an assault.

That gives construction choices real consequences: placing a valuable system high on the tower may protect it temporarily, but losing lower floors could eventually bring the entire structure down. The campaign is planned to include 30 stages and is designed for offline play, with the developers also emphasising the absence of advertising and in-app purchases. Those choices make Siege Foundry unusual in the current mobile market, where strategy games are often tied to online progression and recurring monetisation.

The compact mission structure could work well on phones because each battle presents a contained engineering problem rather than an endless base-building commitment. Success will depend on whether the different floors, weapons and enemy types create enough meaningful combinations across the full campaign. If they do, Siege Foundry could offer a refreshing premium-style alternative for players who enjoy construction puzzles and tactical experimentation.
