A Superweapon is an item which can cause massive destruction, or give a player an advantage. Abilities fitting this description exist in Civilization stage and Space stage.
Civilization stage[]
Global controllers[]
In Civilization stage, if you have 6 cities, there is an ability that allows you to take all cities.
Space stage[]
Use these superweapons carefully and wisely. They will all break the Galactic Code. They are all useful tools for allying with the Grox, especially the Planet Buster.
Planet Buster[]
The Planet Buster is a huge missile that can destroy an entire planet. The term Planet Buster is likely a reference to Sid Meier's Alpha Centauri, or Ratchet & Clank's PlanetBuster Maximus. Once unlocked by earning Colonist 5 or Conqueror 5, the Planet Buster is available for purchase as an ammo-based weapon. Use of this weapon however, breaks the Galactic Code.
Gravitation Wave[]
The Scientist Philosophy gains the Gravitation Wave ability upon entering the Space stage. Although it has a high cooldown, use of the Graviton Wave will destroy all cities and tribes on a planet, effectively neutralizing the planet without harming the wildlife (and thus, preserving its T-Score) leaving it open as a prime candidate for colonization. This ability breaks the Galactic Code.
Fanatical Frenzy[]
The Zealot Philosophy gains the Fanatical Frenzy ability upon entering the Space stage. Although it has a high cooldown (higher than the gravitation wave), use of the Fanatical Frenzy will take over all cities of the planet in one click, but can't be used on a planet where the race is lower than the Space stage. This ability breaks the Galactic Code.
