Defend the planet

"Clank is in need of repairs. You'll be able to fix him up back at the garage."

- Mission description

Defend the planet is a mission in Ratchet & Clank. After Ratchet and Clank crash landed in the Tobruk Crater on planet Novalis, they found the planet under attack by the blarg, due to Mayor Abner Buckwash' nephew Skidd McMarx accessing illegal Hydroharvester schematics. The two then sought to defend the planet from the attack.

This mission must be completed for the mission "Find someone to help you repair your ship", and the Plumber will not repair Ratchet's ship until completed.

Walkthrough
From the starting area, after using the vendor to refill ammo and purchase any additional Raritanium upgrades or new weapons, take the elevator down to the area below and head left. Here, birdbots and peckbots can be found hovering and flying in the air, but will land as you get closer, descending to attack you. Birdbots fire ranged blasts, while peckbots are purely melee. Dispatch of peckbots with either any weapon (though the Pyrocitor is quickest, or the Fusion Grenade with some area of effect Raritanium upgrades purchased), before defeating the birdbots from a range (with either the Fusion Grenade or the Combuster). Defeat enemies along this area, destroying crates for bolts as usual, then head up the stairs on the far left and into the structure connecting to the bridge.

As you cross the bridge, a blarg saucer will destroy parts of it, requiring you to avoid falling through. Defeat the birdbots on the other side and cross the other side, and Mayor Buckwash' crashed ship will be revealed across a path. Cross the path, defeating birdbots and peckbots along the way, and a group of birdbots and blarg troopers will be found. Defeat these, and Mayor Buckwash will appear, providing an infobot with information on his nephew, Skidd McMarx, on planet Aridia. This completes the mission.

After this, if the Plumber had already been rescued, returning to your ship will also complete "Find someone to help you repair your ship". If not, take the elevator up to your ship, turn left into the tunnel leading to the waterworks, and complete that mission to leave and travel to Kerwan or Aridia.
