ARK: Idle Tower Defense

Build your defenses. Choose your skills. Protect the core.

Face mysterious geometric fleets in a space-themed idle tower defense game where automatic combat meets strategic upgrades. Your weapons handle the shooting. You decide how to grow stronger and survive the next wave.

AUTOMATIC BATTLES, MEANINGFUL CHOICES
Watch your orbital defender intercept approaching enemies without constant tapping or manual aiming. Study the battlefield and decide whether your next upgrade should deliver more damage, improve your defenses, or support your existing skills.

BUILD A DIFFERENT LOADOUT
After each wave, choose one of three cards to unlock a skill or strengthen your current build. Combine your pulse weapon with up to four additional skills. Limited slots make every choice matter: build around concentrated damage, area attacks, slowing effects, or a balance of offense and survival.

UNLEASH SCI-FI WEAPONS
Burn enemy paths with orbital lasers. Strike groups with homing missiles and proximity mines. Slow advancing enemies with a gravity well, push them back with sonic rings, and deliver repeated lightning strikes. Discover combinations that work together.

MAKE EACH RUN COUNT
Spend collected data on permanent upgrades between battles. Improve weapon damage, attack intervals, range, core HP, and regeneration. Strengthen your foundation and return to earlier challenges with a new plan.

EXPLORE 30 STAGES
Advance through distinct cosmic battlefields and confront powerful bosses. Clear stages to unlock the next challenge, then test your growing defenses in the final endless stage.

COLLECT REWARDS WHILE AWAY
Return to claim offline data rewards and invest them in your next upgrades. Your preparation continues even between play sessions.

PLAY AT YOUR PACE
Enjoy geometric enemies, glowing weapon effects, and a portrait layout. Adjust music and sound effects, and choose from 10 display languages.
