About
Aliens are invading the Solar System. Defend it planet by planet, from Neptune to the Earth.
Shoot the alien ships down before they fire at the planet. Drag to turn the planet: half of the enemies attack from behind it, and arrows on the screen show where they are.
How a game works:
- Each planet lasts 45 seconds. In the last 10 seconds the enemies move faster.
- If the planet's life drops to zero, the game is over.
- Every planet brings a new enemy. The kamikaze dives at the planet, the splitter breaks into two fragments, the ghost turns invisible and the medic gives the others their shields back.
- The boss waits on the Earth. Destroy it to win the campaign, then keep playing on random planets.
You start every game with 5 nukes. A nuke destroys every enemy on the screen. When you run out, shot-down ships can drop new ones.
Your best score goes on the Game Center leaderboard, and there are 27 achievements to unlock.
The game is in English, Italian, German, French, Spanish and Portuguese.
The game is free and shows ads. You can remove them with an in-app purchase from the main menu.
