Being polite to him, Biggs will explain to them that he believes the robot pursuing them may be an Imperial weapon they brought here in order to study it and hopefully find a way to destroy those wrecking chaos on the battlefield. He'll mention engineers were working on an experimental weapon to fight it before the facility was closed and it still should be somewhere on the second floor.

By the time he's done saying that, the robot will have caught up on them and will attack them all once again. Biggs will help them fight it, and they can chose to:

> All fight it
> Leave Biggs fight it alone and run away
> Split up and have some help Biggs and some run away
> Anything else
