Only the current version so far — new entries appear as the game ships updates.
Solar Defense is a fast space tower defense game where planets are your towers. Alien ships pour in from deep space toward your home star — place planets in orbit, turn them into weapons, upgrade them mid-wave and hold the line.
🪐 PLANETS ARE YOUR TOWERS
Every orbital slot is a tower spot. Drop a planet, watch it open fire, and spend the energy from each kill to upgrade it on the spot. Damage scales fast — one well-timed upgrade can flip a losing wave.
☄️ THREE PLANET TYPES, THREE TACTICS
- Rocky — steady kinetic damage, your backbone
- Ice — slows ships so the rest of your defense finishes them
- Volcanic — burn damage over time, deadly against big hulls
More planet types unlock as you push deeper into the galaxy. Mixing them is the whole game.
🌌 A GALAXY TO DEFEND
- Multiple star systems, each with 10 levels of rising difficulty
- Boss waves at the end of every system
- Earn up to 3 stars per level
- Spend crystals on permanent meta-upgrades between runs — your towers get stronger across the whole campaign
⚡ BUILT FOR SHORT SESSIONS
- Landscape, one-hand controls: tap to place, tap to upgrade
- A level takes a few minutes — a real TD match on a coffee break
- Damage numbers on every hit so you always see what's working
- Fully offline — play on a plane, on the metro, anywhere without signal
🛡️ REAL TOWER DEFENSE, NOT IDLE
No auto-battle, no waiting for timers. Where you place a planet and when you upgrade it decides the wave. If you like classic TD strategy — Kingdom Rush-style placement with a sci-fi twist — this is for you.
Think fast, place smart, and don't let your star fall.
