Order 66 in Solar Smash is a secret achievement and Star Wars reference that requires players to launch exactly 66 missiles using the custom launch settings. Unlocking this hidden protocol rewards you with the secret Lightsaber weapon, which lets you manually carve up planets.
Most players fail to trigger the achievement because they use standard single-fire or default multi-launch configurations instead of manually inputting the exact numeric values required by the game's hidden trigger system. Getting it right takes less than a minute once you know where to look in the weapon menus.
How to Set Up and Execute Order 66
To complete the achievement, open Solar Smash and configure your missile payload using the advanced launch menu. You don't need a specific planet map, so default Earth works fine for the test.
- Open the weapon menu on the right side of the screen and select the Missile Attack tab.
- Choose the Multiple Missiles option, which allows you to adjust row values.
- Set the top row value to 5 and the bottom row value to 66.
- Aim your crosshairs anywhere near the middle or center of the planet.
- Fire the volley. As the 66 missiles impact the surface simultaneously, the achievement unlocks instantly.
If the achievement doesn't pop up on the first try, check your row inputs. The game requires that exact numeric combination in a single salvo to register the Easter egg.
What Do You Unlock With Order 66?
Completing this challenge unlocks the hidden Lightsaber tool. Once unlocked, this tool appears in your arsenal, allowing you to slice canyons, carve grids, or scorch the crust of any celestial body in the game.
The Lightsaber behaves like a physical beam tool. You can drag it across continents to split planets apart or burn deep trenches into the core. It's one of several pop culture Easter eggs hidden inside the game, sitting alongside other complex unlocks like the Cube Earth and the Number of the Beast achievement.
Common Mistakes When Trying to Unlock Order 66
Players often run into roadblocks when attempting this achievement for the first time. Avoid these frequent errors to save time:
- Firing single missiles: Clicking the standard missile button 66 times manually doesn't count. You must use the multiple missile configuration panel.
- Incorrect slider values: Mixing up the top and bottom rows prevents the game from recognizing the command sequence. Make sure the bottom row reads 66.
- Aiming off-planet: If your barrage misses the target or flies off into deep space, the game won't register the impact criteria. Keep your reticle centered on the globe.
Other Secret Achievements Worth Unlocking
Once you've secured your Lightsaber, Paradox Interactive and independent sandbox titles often lean into similar hidden challenges that reward experimentation. Solar Smash includes several other secret tasks you can knock out during your next session:
- Number of the Beast: Reduce Earth's population down to exactly 666 million people before resetting or destroying the world.
- Cube Earth: Open the grid edit tool, adjust the coordinates systematically, and trim the excess crust to transform a round planet into a geometric cube.
- Sunburnt: Jump into System Smash mode, grab the planet mover tool, and throw the Sun directly into another planet.
Frequently Asked Questions
Do I need to destroy the entire planet to get the achievement?
No. You only need to fire the volley of 66 missiles using the correct menu settings. The planet doesn't have to blow up completely for the achievement to register.
Can I use the Order 66 trick on custom planets?
Yes. The multiple missile configuration works on custom planets, standard Earth, and other celestial bodies in the system view.
Where does the Lightsaber go after I unlock it?
Once unlocked, the Lightsaber icon populates your weapon inventory permanently across your sessions, allowing you to select it whenever you want to carve up a new map.
Why didn't my multi-missile attack trigger the reward?
Double-check that you used the exact numbers specified (5 on top, 66 on the bottom). Any variation in those fields will treat the strike as a normal custom attack rather than the secret protocol.
