Unlimited Tower Defense

Defend the castle. Survive the waves. See how far you can go.

Unlimited Tower Defense is a bright, fast tower defense game where the waves never stop. Build towers along the path, drop heroes where they help most, and upgrade on the fly while the monsters pour out of the cave. When your castle finally falls, everything you earned makes your next run stronger.

BUILD YOUR DEFENSE

• 14 towers to unlock and master: Gunner, Mortar, Laser, Frost, Sniper, Fire, Poison, Railgun, Bank, Plague, Missile, Cryo, Beacon and Inferno.
• Upgrade damage, fire rate and range mid-battle with the cash you earn from every kill.
• Tap monsters to hit them yourself when things get close.

BEAT THE BOSSES

• A boss arrives every 10 waves.
• 13 boss types, each with its own twist. Some split, some summon, some shrug off the wrong towers. Read the card, pick the right towers, win.

HEROES JOIN THE FIGHT

• 10 heroes, from the Knight to the Ninja. Drag one onto the map and everything inside its circle gets stronger, faster or luckier.
• Level heroes up with Hero Cards and research.

GET STRONGER EVERY RUN

• Forge: spend gold on permanent upgrades for every tower, your castle and your income.
• Labs: timed research that keeps paying off, run after run.
• Tech Tree, Gold Mine and cards you equip for bonuses every run.

60 STAGES. WAVES THAT NEVER END.

• New maps, new monsters and new challenges as you climb from Stage 1 to Stage 60.
• Every stage keeps going as long as you can hold. Chase your best wave and push past it.

PLAY YOUR WAY

• Speed up the game when you are strong, slow down when it gets tense.
• Daily rewards, quests and milestone chests.
• Ads are optional: watch one only when you want a boost.
• Back up your progress with Sign in with Apple, or move it to a new phone with a transfer code.

Free to play, with optional in-app purchases.
