Let's think of new traitor objectives here!

[Gannets]

Maybe some department specific sabotage, with a couple of different ways to fulfill them.

Sabotage genetics
-Destroy all cloning equipment or have it unpowered when the shuttle leaves.

Sabotage station power
-Destroy the engine or disconnect the engine from the power grid.

Sabotage trading
-Destroy or depower the qm trading console or destroy the qm mass-drivers.

Something like that, having traitors designed to ruin certain departments, with a few ways of succeeding.
