The Tetrabomb Gun is the upgraded form of the Hoverbomb Gun in Going Commando, and is an extremely powerful weapon. It functions exactly like the Hoverbomb Gun, except it fires five Hoverbombs instead of just one. These bombs spread out as they float along, making them very effective with an incoming enemy wave heading for Ratchet. The sheer overwhelming power of the bombs is such that they actually exceed the power of the average RYNO II rocket, making it extremely effective on bosses and vehicles such as the Hovertank. However, the RYNO II's higher rate of fire makes it more popular among users.
