Description
You are most likely looking for a game like Solar Smash (also called Planet Smash Destruction). These are physics-based sandbox games where you are given a full solar system and a massive arsenal of weapons to destroy planets in spectacular ways.
Gameplay: You select a planet (like Earth, Mars, or fictional worlds) and use various tools to destroy it.
Weapons: Your tools include lasers, asteroid impacts, nuclear missiles, black holes, giant space monsters, and alien UFOs.
Goal: There is no "goal" other than to creatively and completely annihilate the planet. It's a popular "destruction simulator" game.
Where to Play: You can play these games for free on web browsers (on sites like gamesst.com) .
"Planet Buster" is also a famous and controversial high-level weapon in the classic game Spore (in the Space Stage).
What it is: It's a single-use item that, when deployed, completely destroys a planet, leaving behind no debris.
How to Get it: It's one of the most difficult and expensive items to obtain.
Consequences: Using a Planet Buster is a violation of the "Galactic Code." This action will instantly make all other space-faring empires (except the Grox) hate you, declaring war and making the game much more difficult.
There are also a few smaller indie games with this exact title:
Planet Buster (gamess.com): A free, 2D top-down space shooter where you fly a ship and have one shot to destroy an enemy planet. This is a fast-paced action game that you can play in your browser.
