Your towers decide where the enemy goes.

Shape the battlefield in a strategic tower defense game with free tower placement. Use your towers to redirect ground enemies through a maze of overlapping fire. Decide where to spend your gold, where to slow the advance, and when to concentrate your firepower.

Fight through three chapters.

Fight through Chapters One, Two, and Three. From the central defense line to snowy battlefields and mountain positions, adapt your defenses to different environments, attack routes, enemy waves, and bosses. In the campaign, your towers carry over between levels, keeping their positions, upgrades, and specializations as your defensive network grows.

Five tower types. Ten specialization paths.

Combine rapid-fire guns, slowing gel, flame blasts, homing missiles, and electromagnetic firepower. Four tower types reach level 4, while the gel tower reaches level 3. At maximum level, each tower offers a choice of two specializations. Build around rapid fire, piercing shots, area slows, lingering burns, missile swarms, or chain lightning to create your own defensive combinations.

Control the route. Seize the moment.

Scout incoming threats, set targeting priorities, and focus fire on dangerous enemies. Relocate towers to reshape your defenses, then unleash a battlefield-wide damage boost or slow when the pressure peaks. Ground troops follow open routes, while airborne enemies bypass your maze. Can your defenses handle both?

Boss Challenge and Endless modes

Each chapter has its own Boss Challenge and Endless modes, unlocked as you progress through its campaign. Start with a fresh setup in Endless mode and face ongoing enemy waves. In Boss Challenge, carry over the gold and tower formation from that chapter's completed campaign to face a succession of bosses.

Study your enemies. Refine your defenses.

Explore the enemy and tower archives to learn enemy mechanics and weapon strengths, and work toward achievement goals as you progress. Refine your firing lanes, crowd control, and skill timing against fast attackers, armored units, and airborne threats.

Build your maze. Hold the line.
