The game first starts with Ratchet and Clank playing some sort of chess game with Clank winning. Suddenly Clank remembers that his show is on and switches the channel to Secret Agent Clank . After the episode, Ratchet asks him to change the channel, as he is only shown as the clumsy sidekick. After Clank refuses, Ratchet grabs the remote and changes it to Channel 2, which is showing a live coverage of Ratchet's home planet Veldin being attacked by an alien race known as the Tyhrranoids (terr-ah-noyds). Apparently, they are being ordered by an evil robotic super genius known as Dr. Nefarious. While the Galactic Rangers are fighting back, they are really no use in the struggle. Darla Gratch signs off, and Ratchet, apparently infuriated by this move against his planet, declares that they must return home immediately to help his planet.
As they are getting ready for take-off, Clank complains about how they are a galaxy away from Veldin. Ratchet, undaunted, prepares the (untested) Gravimetric Warp Drive. Clank is not confident about the device, but is proven wrong as they arrive at Veldin.
Veldin
A nice and easy tutorial for the game. As soon as you land, you will be greeted back home and will see a duo of Rangers fighting off some 'noids. Don't bother helping them, they'll finish them off themselves and run around the corner. Don't follow them just yet, take a moment to look around and smash any boxes with your wrench (
). After you have scoured the area for spare bolts and crates, go around the corner to meet the Rangers.
The Rangers greet you, their new Sergeant, and give you you your first weapon, the Shock Blaster. Straight afterwards, a Tyhrranoid in a green exoskeleton comes around the corner. The Rangers wuss out and run off leaving you to deal with it. Shoot it into pieces with the Shock Blaster (
).
