Contract Name: "47 Van Helsing".
1) You must start the mission with this loadout. (Note: However, you can choose any smuggled item you like, and wear any outfit you like.)
2) You can NOT subdue or kill anyone except for the targets inside the Caruso-mansion grounds. You must leave all Ether employees except for the targets completely unscathed. You are, however, free to subdue or kill NPCs outside of the Caruso grounds.
3) You must kill the priest following the six steps outlined in the briefing (see above).
Optional Special Condition: It's not necessary, but if you kill the Bozzuto brothers in the kinds of accidents described in the mission briefing, you receive an additional star (Hitman symbol) to your score. Which means, for example, that if you SA the contract and complete this optional special condition, you receive a 6-star rating from me here in the thread.
Advice: If you attempt this optional special condition, don't take any risks with guards. Don't assume guards can't see you because they're a long way away, or because their backs are turned. Their heads can turn and they can spot you. I know this from experience. Use appropriate distractions and pay attention to where guards are looking, not just to where they're standing.
This contract expires in one week on Monday, at 6 p.m. GMT (1 p.m. EST).
Good luck, and feel free to ask me if you have any questions.
P.S. You'll have to right-click and save the briefing description to your computer to be able to read it all. Sorry about that. I wrote a little more than I intended.
