Build towers and survive through 51 hardcore waves of aliens that heal themselves, haste other enemies, split into more enemies and freeze your towers.
Keep your base safe from the huge advancing army using your trusty sniper rifle, air strikes and artillery. With each wave the invading army gets stronger, spend your money on the right upgrades and try to survive the war!
Defend your land from invading enemy troops. Build defensive towers along the road strategically choosing which type of tower to build, upgrade them in time and always be one step ahead of the enemies.
Destroy the enemy base while defending yours. You can build turrets to defend your base and units to attack the enemy's. The twist of the game is that you can evolve as well as unlock new units and defense means.
