The two of you rush through the hole as you hear a spray of gunfire followed shortly by a guard yelling "Do a headcount, find out if anyone escaped!"
Sounds like you two have some time as you emerge into a ramshackle area of broken down buildings and decaying hunks of metal. You'll need to head out quickly and you know there are going to be patrols in this area, after all you'd heard the sounds of footsteps and voices come from the outside of the camp.
