Stack Defence
Stack Defence is a tower defense game with a unique stacking mechanic for building your defenses. Place defensive units on a stackable grid, building upward to create layered defense structures against incoming enemy waves. The vertical stacking adds a strategic dimension beyond traditional tower defense, as height affects range and effectiveness. Different unit types offer various defensive capabilities, from basic attackers to support units that enhance nearby defenses. The game features multiple enemy types with different strengths and movement patterns, requiring varied defensive strategies. Upgrade your units and unlock new types as you progress through increasingly difficult waves. The stacking mechanic creates a fresh take on the tower defense genre with deep strategic possibilities.
