100 scenarios. Your defense. Always free.

GRID DEFENSE: GRID WAR is a sci-fi tower defense game built around varied towers, six heroes and powerful ultimate abilities. Place your towers, stop the incoming waves and choose when to unleash your strongest attacks. All 100 Scenario stages are free.

22 towers. Build a defense that works together.

Artillery, freezing attacks, electrical weapons, lasers and anti-air fire give your defense different ways to answer a threat. Combine the roles of 22 tower types: control an approach, cover a vulnerable lane and concentrate fire where it matters. Your placement shapes the battle as much as your choice of weapon.

Ground forces and aircraft put different pressure on your line. Read the incoming attack, support your towers with heroes and decide when to commit your strongest abilities. Heavy enemies and bosses test the whole defense, from its firing positions to the timing of its support.

Six Wardens, six roles on the battlefield

• VANGUARD — mobile assault fire to meet threats along the front.
  
• LONGVIEW — long-range precision and powerful single shots.
  
• BULWARK — heavy area bombardment against clustered enemies.
  
• MENDER — repair support for damaged buildings.
  
• TINKER — a support field that strengthens nearby towers.
  
• SKYWARD — heavy rockets and explosive attacks against ground and air targets.

Turn the battle with 26 support options

Your arsenal includes 26 support cards, with four robot-unit cards among them. Bring airstrikes, missile barrages, EMP disruption, battlefield control and reinforcements into your strategy. These choices add another layer to the towers already holding the line.

Spend an attack to stop a wave now, or hold it for the threat approaching behind it. A well-timed ability can support an exposed position, break a concentration of enemies or help your defense face a boss. Choose your moment and make the whole force work together.

A complete 100-stage Scenario campaign, always free

Fight through 100 Scenario stages across 10 chapters. From the first crossroads to changing fronts and heavy enemy assaults, the campaign gives your growing command of towers, heroes and support abilities room to develop. All 100 stages are free; reaching later Scenario chapters does not require buying the paid modes.

For additional battlefields, Basic and World offer paid tower-defense modes. GRID COMMAND takes the action into the air with a different style of combat.

Command the skies in GRID COMMAND
