Tower defense strategy against an AI robot army, and a carrier war in the sky. Build towers, lead six heroes and drop a nuke when the horde breaks through. Then take command of a flying carrier for air combat over 25 real cities. A sci-fi strategy game you can play offline.

Start with the Scenario campaign: all 100 stages are free to play. Basic, World and GRID COMMAND are premium modes, unlocked together by one purchase.

New in 1.1.0: GRID COMMAND
• Fly your carrier over 25 real cities, with bigger arenas and more enemies
• A clean phone HUD: a fixed stick and four buttons (Build, Ultimate, Boost, Attack), and the hull bar right on your carrier
• Carrier towers: build all six side towers from one panel
• Helicopters airdrop your ground towers into the fight
• Rescued heroes hang under the carrier and keep fighting
• Call in the I-series units, with IRIS on the radio

Build your defense line
Place 22 tower types: artillery, freezing, electric, laser, anti-air and more. Robot troops, tanks and aircraft hit your line from every side. Where you build matters as much as what you build.

Six heroes, six jobs
• VANGUARD – fast assault on the front line
• LONGVIEW – long-range sniper
• BULWARK – heavy area bombardment
• MENDER – repairs damaged buildings
• TINKER – powers up nearby towers
• SKYWARD – heavy rockets against ground and air

Call in the big guns
Pick from 26 support cards and unleash ultimate strikes: airstrikes, missile barrages, EMP and nukes. Fire now to stop this wave, or save it for the one behind it.

Real cities, giant bosses
In World mode your battlefield sits among the outskirts of 15 real cities. 20 giant bosses march straight into your tower line.
