About
Earth Orbit Defense is a fast-paced sci-fi arcade defense game where Earth sits at the center of the battlefield and hostile orbital material fields choke the planet. Rotate the world, clear the ring, survive timed missions, and build a stronger defense network across 600 handcrafted levels.
Fight through escalating chapters, break dense orbital debris fields, and unlock the next frontier only when your upgrades are strong enough. Every mission pushes you to balance speed, precision, and long-term progression.
Features:
- 600 campaign levels across 20 escalating chapters
- Auto-fire combat with planet rotation control
- Long-term upgrades for damage, fire rate, and orbit drive
- Timed research progression with instant-finish Time Tickets
- Optional rewarded boosts for 2x Gold, extra time, faster research, and temporary 2x fire rate
- Game Center leaderboard support
- 10 supported in-app languages
- Premium tactical sci-fi presentation built for portrait iPhone play
Can you clear the ring, protect Earth, and survive every orbit?
