Imperial Cruiser

Tachyon's imperial cruiser was the the ship that chased Ratchet on the grindrails and confronted him at the end of the path. Ratchet escaped Kerwan in this ship fleeing to Polaris. Along the way Ratchet was gassed by cryosleep which made Clank feel good about the fact that it didn't work on robots. The ship then knocked out Clank causing him to have a dream. The ship crashed on Cobalia where the duo had to find a way to get off the planet.
