About Siegecaster
Siegecaster is an active, skill-based siege defense game. You build and expand a base to protect your citadel, then wield an arcane arsenal and wizard abilities against an unrelenting enemy onslaught. Surviving battles earns runes that you use to strengthen your weapons and power.
Build your defenses
Each level offers multiple base locations, so you can choose where to start and plan your strategy. Build outward using wall-piece designs and encircle powerful runespires to increase your turrets’ power. The onslaught never stops, so you need to keep building and fighting.
Runes and abilities
You can insert each rune into any weapon, in any combination, to modify the Siegecaster’s arsenal. Choose a rune inventory to suit your playstyle, then earn, upgrade and enhance runes between missions to increase your power. You can also cast wizard abilities and customize them with different spells.
Enemies and levels
You face a variety of enemies, including powerful rune goblins, and need to choose the right weapon for the fight. Death is almost certain; survivors encounter more powerful enemies and new biomes. Levels take place across several fantastical biomes in the Siegecaster universe, and each has multiple starting locations.
