Journey outside the airlock (2002 game)

Journey outside the airlock was a mission in Ratchet & Clank. Ratchet and Clank found an airlock to the exterior on the Blarg Tactical Research Station, as Ratchet was unable to survive in the vacuum of outer space Clank was sent to explore in his stead. After a short trip through outer space Clank returned with a Hydrodisplacer.

Walkthrough
Clank controls notably different from Ratchet, aside from being smaller and thus slower, he lacks a double jump and any of Ratchet's specialized weaponry, he can still use the Heli-Pack to glide however. Begin by following the thin swerving path across a fuel line to enter the first spaceship, beware of the lone alien swarmer, for it is faster than Clank. Note the crate you can jump on to the left, which allows you to enter the bridge for a few more crates. Exit through the rear and glide across the gap. After exploring, another fuel line leads to the next ship, in which you will encounter a stationary alien snapper blocking a doorway. Ignore it and instead break open several glass cases behind a number of pipes to free the Gadge-Bots.

Gadge-Bots are little robots that Clank can command using and the  buttons. Command these to destroy the snapper, which they will do with ease. Recover any that do get destroyed from their starting location and then continue into the next room where you must order them to enter a machine with a large four floating above it, next to a doorway blocked by a forcefield this time. Once all four Gadge-Bots have entered the forcefield deactivates, allowing you to pick up the Hydrodisplacer and return to the airlock with a newly opened bridge.
