Protect The Planet’s rotating defence against asteroids and alien raids
Protect The Planet drops you into an arcade defence challenge where you spin the globe to face incoming threats and keep the surface alive. Asteroids, enemy ships, and new settlers all arrive in the same orbiting playground, so every move has to serve both survival and expansion, no download needed.
Spin the planet to block incoming danger
The core move is simple: rotate the planet so the right side meets the next wave first. That matters because meteor strikes and hostile craft can come from different directions, and one bad angle leaves your settlements exposed. If you want a closer mechanical match, Alien Attack also leans on hostile space pressure, while Star Wing keeps the action focused on fighting in orbit.
Grow while you defend the surface
You are not only holding back attacks; you are also helping a new civilisation take shape on the planet. As citizens and buildings appear, the stakes rise because your defence has to protect both people and construction, not just the core itself. That mix of expansion and protection gives the round a strategic edge, and you can chase a higher survival run free online in your browser.
Action strategy with constant pressure
The pace stays brisk, so you need agility and timing instead of long planning. Each turn of the globe changes what is vulnerable next, which is why the game rewards fast reactions and smart prioritising when multiple hazards overlap. For another planet-focused blast, Solar Smash scratches a similar space-scale itch, while the space, building, and aliens themes all show up right on the surface.
That pressure makes every run feel like a test of how long your colony can hold together under fire.
