Repair the IRIS is a mission in Tools of Destruction, taking place inside the IRIS Supercomputer on Kreeli Comet. Ratchet and Clank found the computer damaged by space pirates, although Clank thought he could fix its CPU from within, with help from the Zoni.
Walkthrough[]
Use your time powers to pass through the rings, then command the Zoni to follow you. Utilize your powers once again to pass through the electricity, and employ levitation to reach the Zoni across the electrified floor panels. With your Zoni in tow, approach the locked gate and sacrifice two Zoni with the "Charge Up" command to open it. Eliminate the buccaneer on the other side and use levitation again to reach the second group of Zoni. Employ four of them to charge the second gate.
In the subsequent room, you can follow the hidden right path to acquire a single bolt, which grants a secret code for the Zoni skin in Secret Agent Clank. Return to the main path, which remains fairly linear. This path features more rapidly rotating rings, pirates (both buccaneers and corsairs), another group of Zoni that you must command, and another gate that needs to be opened with the charge command. After opening this last gate, pass through the electric barriers to reach the CPU, which can be repaired using the manipulate command, thereby concluding the mission.
After the cutscene, you can ask IRIS several questions (there are more options than shown on-screen at once). Once finished, use the teleporter to return to the Aphelion and head to planet Viceron for the mission "Grind the Rails to the Prison".
