Just a heads up, I have no internet currently, so I can't post. On my phone for a little while.
@Suku, basically the team reconvened in the control room after getting their respective missions done, then jumped/flew out of an open bulkhead. The prison itself is located in the middle of a vast desert, home to a variety of monsters, including the everybody's favourite sandworms. Once the team landed, one of the turncoat soldiers got eaten, so the team is running like buggery to the nearest rock formation to give themselves a chance.
Bear in mind though that even if the worms can't tunnel into rock, they can still attack the team until they're far enough away from the sand.
