Necropolis 2350. Your unit has been assigned to capture and interrogate a vampire.
Vampires in this setting:
-are not destroyed by sunlight
-do not feel pain
-tend to have between d12 and d12+2 Strength
-are not affected by garlic or holy items (except those of unusual power - the Spear of Destiny or Holy Gail might do something, while your garden variety holy water does not; let us assume the group does not have access to a powerful relic)
-are sentient, free-willed creatures
How do you go about getting information from that thing?
