## What is GRIDLOCK?

Build a maze from above. Fight the horde inside it.

GRIDLOCK combines maze tower defense with a retro first-person shooter in a procedural voxel world. Place walls, build towers and upgrade your Nexus between waves, then drop into first person to defend it as an armored alien guardian.

A HORDE THAT LEARNS
Enemies share what they discover. Unseen walls stay unknown until a scout finds them, and the whole horde changes its route together. Their memory resets each wave, giving every maze a fresh start.

BUILD, FIGHT, ADAPT
Draw thin walls, including diagonals. Combine Gun, Cryo, Mortar and Railgun towers with support buildings. Upgrade your weapons, time perfect reloads and use the chainsaw when enemies get close.

20 ARENAS, 31 ENEMY TYPES
Face 12 bosses, unlock arenas, discover the Codex and earn 60 achievements. Later maps introduce multiple entrances, multiple cores and moving entrances.

PLAY YOUR WAY
Choose Standard mode or Timed Assault. Adjust sensitivity, reduce camera motion and set music and effects volume separately.

OFFLINE AND SELF-CONTAINED
No account, ads or in-app purchases. All game assets and audio are included. Your progress stays on your device, with automatic build-phase checkpoints. Interrupted combat waves restart from the latest checkpoint. There is no cloud sync.
