Solar Smash Machine World
The Solar Smash Machine World is one of the most played after the Earth. It’s a Dyson Sphere shelled with metal and hiding a pulsating blue star inside. 800 million aliens inhabit this bulletproof orb. It will let you crush it for the first five times. But then, the planet will become more hostile.
Surprisingly, the core power shields the outer surface, making it invincible. No beam, Planet Killer, or even black hole can break through this cover. But if you’re determined, everything is possible.
