Evil Genius 2: World Domination

Wanted to note here, this applies to most of the other trap-based achievements as well. When you have captured agents, you can use traps to interrogate them. Whichever trap you select will activate, and other traps that the agent is in range of will activate as well. A side note, if the minion who is interrogating is also within range of other traps, they won't activate. The interrogator will also stand a couple squares back from the agent they are interrogating.
