Spire Bastion is a fresh and simple tower defense that feels good to pick up and play. Enemies climb the spire toward your Crystal Core. You drag to place heroes and they auto-fight, so the focus stays on calm decisions and satisfying results.

Features
● 3D terrain matters: geometry changes range, lines of fire, and chokepoints
● Light strategy: simple skill combos that feel smart without heavy micromanagement
● Floor-by-floor climb: each layout offers a small twist and a new idea to try

Play at your own pace, let the map guide your plan, and protect the Crystal Core. Drop in, relax, and enjoy the climb.
