## Description

Defend your planet from the UFO swarm — Mars, Venus & Titan events, satellites and offline play. In English, Русский, Español, Português, 中文.

Your planet is under attack. Hold the line.

Planet Defense: UFO is a fast, tactile space tower-defense: your home world sits at the center, alien ships swarm in from every direction, and every decision happens in seconds. Tap to build satellite turrets, upgrade your firepower mid-battle, and collect the coins your planet generates — then push one level further.

BUILD YOUR ORBITAL DEFENSE
• Tap "+" slots to deploy satellite turrets around your planet
• Upgrade 8 combat lines mid-run: damage, fire rate, range, bullet speed, satellite speed, pierce, repair and shields
• Every level unlocks more build slots — and brings bigger waves

FIGHT A REAL INVASION
• 6 enemy types with their own tricks: swarmers, speeders, tanks, splitters, exploders and turret-hunting shooters
• Enemies get tougher with every city — your defense has to evolve
• Lose the planet and you restart the city: your permanent progress always survives

GROW STRONGER FOREVER
• Earn cores from kills and victories, even when you lose
• Spend them on permanent upgrades: starting damage, planet HP, coin boosts and more
• Deep upgrade curves reward long-term investment

ROTATING LIVE EVENTS
• A new planet needs you every 2 days: defend Mars, Venus and Titan
• 5 difficulty tiers from Normal to Nightmare — pick your challenge
• Complete event tasks for huge core rewards, then admire your winning defense

PLAY YOUR WAY
• Sessions as short as one level or as long as one more city… again
• Optional rewarded boosts — no forced ads, no energy system
• Fully playable offline; localized in English, Español, Русский, 中文 and Português

Can you hold every city?
