Our take on Siegecaster

The store copy foregrounds hordes, runes, and an expanding arsenal, but the core activity also depends on careful wall placement and rapid aiming. It presents the action prominently while giving less emphasis to the planning required to connect defensive building with weapon upgrades.

What is Siegecaster?

Siegecaster is an active siege-defense game centered on aiming weapons and managing a growing citadel.

Each level offers several possible starting positions, allowing players to choose where to expand their walls and how to reach rune spires. Surrounding these structures grants runes that modify weapons, while defeated rune goblins and completed battles add to the rune collection. Runes can be upgraded between missions and assigned across the arsenal in different combinations. Players also cast wizard abilities and select spells for their preferred approach. Enemy attacks continue without pause, and surviving battles introduces stronger foes and new biomes. The game includes multiple enemy types, turret upgrades, controller support, and an original soundtrack.
