Joltship

The Joltship is the ship that destroysThera on the mission Vaccine. Not alot is known about this ship, not even what it looks like although like everything else in this game we can always theorize.

Everything We Know So Far
The Joltship never makes an official apperance, but in an official image from NinjaKiwi there appear to be two cruiser type ships near a spaceport identical to Kurios spaceport with three military shuttles flying near them. Although these may not be a joltship, they might be a different version of the cruiser ships designed to be a 'Planet Cracker" type ship.

The ship almost certantly uses JOLT technology (J-tech for short), which is the same technology that the Zerfallen  uses, although due to how Thera Explodes the Joltship may utalize this J-tech in a different form than the zerfallen, as the zerfallen shoots slow traveling orbs.
