Well, moping won't help! Get to it! You have actually made it to your ships. The emergency systems basically
a. remove the clamps that are holding them in place for maintenance
b. shoot them down the conveyance system to the hangars.
The system is normally droid operated; the main control link for it was, of course, just frazzled in error by Galder, but in the event of an emergency the ships can be released by these systems as you now plan to do.
Those Osokans look quite mean though. Luckily they are about 30 seconds way from you as we start.
I'm happy to have Galder do some technical work in Rex's absence. In fact, he can be activating the conveyance, wgilst you guys cut the links loose.
This time Galder rolls +5. Damn good thing too. And luckily these supports are relatively thin but made of a high-strength, high-tensile material which your lightsabres munch through with little hassle. The ships are freed almost at once. As ever, the Cynelline technology is sophisticated but utterly unused to people like you.
