The gravimetric warp drive was a homemade device that Ratchet built from Blargian scrap metal. It allowed one to travel through space at incredible speeds, even allowing one to jump between galaxies. When Ratchet returned to Solana in the Star Explorer to save Veldin, Clank was concerned because the device had not been properly tested. However, it warped the duo through Solana Galaxy and to Veldin in one piece.
