Replicants as an Antagonist

[Weavel]

I have an idea for a unique objective for these guys. There's tons of gear that's very department orientated. Maybe it could be the replicant's goal to steal these items, disassemble them, and use the pieces to upgrade themselves.

Steal botany's chainsaws, or use certain plants to create biofuel.
Grab the Captain's E-gun to steal the focusing lens for the laser.
Get a tank of super heated gas from Research or Engineering.
Get certain components from Mechanics.

The crew would be motivated to stop you purely as you'd be an annoyance to their work, and they wouldn't necessarily need to use violence to achieve the goals.

This is the subdued less-murderous sort of objectives I've been looking for! I like that they might need to mug someone, break in somewhere serious, and end up all over the station with their goals. Seems fun.
