About this game

Walls bend the path. Towers counter the creeps. Grid Lockdown is a single-player maze tower defense and offline TD strategy game where you build the route yourself and decide how long the creeps have to walk under fire.

Every run starts on an empty grid. Place walls to build a maze, then place towers beside the path. Each tower is strong against some creeps and weak against others, so the maze and the towers have to work together.

- Five towers: Sentry, Lance, Chill, Mortar and Arc, each with its own job and its own upgrade path
- Creeps that need different answers: runners, dashers, swarms, tanks, brutes, shielded Aegis, healing Menders, Nulls, flying Skimmers and splitting Hive Nodes
- A Core Warden boss every 10 waves
- Wave twists such as plated, warded, rushed and siege waves
- A relic at the start of each run that nudges how you play
- Easy and Hard, 50 waves each. After the clear you can keep going or bank the run
- Crystals earned each run buy upgrades that stay with you: starting capital, attack speed, range and extra lives
- Tower info shows what each tower is good against and what it struggles with
- Three game speeds, so a quiet wave does not take long

There is no account to make and nothing to buy. Your crystals and best wave stay on your device, and you can delete them from Settings, About. The game works offline once it has loaded.

Ads are optional. You can watch a rewarded ad for extra crystals, gold or one more chance, and a short ad can appear between waves after the game has been open for a while. Ads come from Google AdMob. Grid Lockdown is not made for children under 13.
