One Turret: Tower Defense

One turret. Every side. No way out but up.

One Turret is a tower defense game where you defend a single turret in the middle of the battlefield. Enemies swarm in from every direction, the turret fires on its own, and every few seconds you choose what it becomes next.

PICK, COMBINE, SURVIVE
- Each level up, pick one of three upgrades: a new weapon, a stronger one, or a boost to the whole turret
- Two of the same weapon at the same level combine into a stronger one with a new look
- Join two different weapons into one of 15 fusions
- 12 weapons to unlock: cannon, shock coil, frost ring, guard orbs, mortar, laser and more
- Parts change how your weapons behave, and six mounts decide how wide your build can grow

BOSSES AND VISITORS
- Every stage ends with a named final boss, and boss waves come with their own health bar
- A demon may offer a pact between waves: a big gain with a cost
- An angel may bring a gift for your run
- Abilities you trigger yourself, like an orbital strike or a repair drone

200 STAGES AND AN ENDLESS RUN
- A campaign of 200 stages across five arenas, each with its own rule and look
- Earn up to three stars a stage: clear it, keep your health above half, beat the final boss fast
- Endless mode for your best wave, and a daily run that is the same for everyone
- Eight tiers of difficulty, each harder and richer than the last

GROW BETWEEN RUNS
- Spend coins on permanent power, extra choices and stage upgrades
- Research in the Lab, equip gear in four slots, try five turret bodies
- Daily missions, a weekly chest, events and a free season pass track
- Offline coins build up while you are away
- 2x speed, and 3x once you reach tier 3, plus auto-pick for long runs

FREE TO PLAY, ADVERTS ONLY WHEN YOU ASK
There is no banner and no advert between runs. A short video plays only when you tap a bonus marked AD: revive your turret, double a run's coins, new upgrade choices, a free starting upgrade, and a few more. None of them in your first two runs, and every one is optional.

OPTIONAL PURCHASES
Everything can be earned by playing. If you want to support the game, the Shop sells No adverts (every AD bonus becomes a free claim), a coin doubler, coin and gem packs, reward lanes, a monthly pass and packs of gear crates. Gear crates hold random gear; the odds are shown above them in the Shop before you buy.
