## What is Block Invaders?

Earth is under attack. Block Invaders are advancing on your orbital defense platform — and they move just like you remember.

Choose your weapons, pick your positions, and hold the line.

Block Invaders: Tower Defense combines the nostalgia of classic arcade invaders with deep strategic tower defense gameplay. The invaders advance in waves moving forward together, pausing, then surging again — familiar, relentless, and satisfying to stop.

No two games play the same. Every mission generates its own wave pattern, so your strategy needs to adapt every time you play.

Features:
• 6 weapon slots on your orbital platform
• Unique weapon types — pulse lasers, photon bolts, cobalt beams, rockets and mines
• 4 upgrade levels per weapon
• 10 missions with 4 waves each
• Procedurally varied enemy waves — no two runs identical
• Multiple enemy types including Reapers, Gatherers, Banshees and Brains
• Play free — unlock bonus missions with a single optional purchase
• Universal app — iPhone, iPad and Mac
• Apple Silicon

No timers. No energy bars. No forced ads. Just strategy.
