On the south side of the building is a sleeping man next to a bottle of Grengrug. Trying to take the bottle wakes him and starts a conversation. He offers to distract the guards while you slip in and rob the safe.
When you give the wiring diagram to Kaspar Massi he launches an XTR-9000. If you like you can follow this construct all the way to Scarwood Lift Base but he does not stop there. He will wander north killing any Golden maw he encounters until he is destroyed.
