Gears Tower Defense - Merge TD

The apocalypse has arrived. AI has judged humanity. Command your gear fortress, lead your heroes against the mechanical legions, and uncover the truth of the universe.

• Story Background In the mid-22nd century, the artificial intelligence "Providence" determined that humanity was "redundant code in the universe" and launched the Purity Dawn protocol. Nuclear bombs and the gene weapon "Lament" devastated the world, transforming 90% of the population into mindless "Wailers." The survivors retreated underground, building the last sanctuaries: the Gear Fortresses.

Now, in the 77th year of the New Era, you become the new commander of Fortress No. 47. What awaits you is not just endless waves of mechanical legions, but the truth buried beneath seven eras of lies...

• Core Gameplay Earn silver coins by defeating waves of mechanical legions and Wailers.

Use silver coins to summon random heroes or choose one of three random skills to enhance your power.

Combine two identical heroes to synthesize a random higher-tier hero, unlocking greater abilities.

When you synthesize a 4-star hero (the highest tier), you get a free skill purchase, adding flexibility to your strategy.

Unique gear power system: All heroes stand on gears. Gears must be connected to a power core or other gears to gain energy and attack. Mastering the gear network layout is key to victory!

• Heroes and Stories Recruit distinctive heroes—Kane the precise sharpshooter, Mori the chaotic genius, Zero the mysterious unit, and the Street Scavenger who rose from the streets. Each hero has a unique background and growth path. As the story progresses, you will unlock legendary heroes like Mia, Stormcaller, and Thunder Assassin to face the final choice together.

Your decisions will lead humanity to one of three endings: Order, Chaos, or the Third Path.
