Planet Buster is a casual destruction game where missiles chip away at rotating planets layer by layer until the core explodes. Currency from each cleared world pays for upgrades that raise missile power and fire rate. Tougher planets and periodic boss worlds with reinforced crusts keep progression challenging.
Gravity affects how bombs arc, so each strike has a tactical angle. Power upgrades, spawn-rate boosts, gravity tweaks, and accuracy improvements stack into a steady one-button loop. Offline progression still earns coins while you are away, and a clean interface keeps the focus on watching surfaces break apart.
