Solar Defense: Space Tower TD

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. Download Solar Defense — a space TD strategy game you can finish a level of in five minutes.
