Security Outfit

Anyway, we found it easiest to start with obtaining a security outfit, although if you're adept at sneaking about, you may be able to grab an orderly uniform straightaway by heading into the tunnel connecting the main building with the medical wing. You'll be escorted out if anyone spots you, but the numerous light switches will hopefully allow you to prevent that occurance.

Still, though, it's easiest if you have a security uniform to work with, and the easiest of those to obtain is of the guard at the camera station, which is recording all of the CCTV feeds for the building. To reach him, head up to the residential suites and enter your own room, labelled A. From there, exit to the balcony and jump off into the courtyard, being sure to land somewhere away from the window, or the guard might spot you. To kill the guard, you'll need to break the electrical box here, then hide on the set of small steps a bit to the northwest; when he comes out to investigate, sneak up behind him and either poison or fiberwire him to take him down. With that done, grab his uniform and dump his body in the dumpster nearby.

Orderly Outfit

Getting the orderly outfit is a bit more difficult. You can find two orderlies in the tunnel connecting the main building and the medical wing, in addition to a few more orderlies that lounge about in the medical wing itself. The orderly in the main office overlooking the padded cells is your best bet.

If you can isolate this orderly, killing him and stealing his uniform is a simple matter.

The orderly we’re going to be targeting is the one sitting in the chair in the orderly office here. Besides him, there’s only one other orderly on the upper floor here, and he often takes a break on the little terrace to the north, preventing him from seeing anything that goes on in the office. After the orderly on patrol comes in for some coffee, he’ll leave and head out to the terrace, allowing you to crawl over the counter here, kill the orderly at the desk, steal his uniform and keys, then dump his body in the bin near the coffee machine, all before the other orderly gets done with his break.

Agent Smith, I Presume

The orderly's uniform unlocks a magical world of intimate pleasures for you...or at least it lets you reach Agent Smith, who's found in the medical wing. You should have the cell key from the body of the orderly you took out, but if not, you can grab one from the orderly office overlooking the cells.

After speaking to Agent Smith, sedate him. (This is an action; you can't equip the death serum specifically.) When Smith is "dead", bust ass out of the medical ward and get back to the main building of the spa. As you heard on the telephone, you now have your target, as well as two optional targets, each of which will net you a $50,000 bonus.

Truth be told, these targets are pretty easy to kill. One of the three periodically lifts weights in the gym, one periodically cooks pasta sauce on his campire stove in his room, and one (your primary target) periodically returns to the library in an attempt to score some hooch from his stash in the globe there.

Poisoning this liquor will kill off your target right quick.

Globe Guy: There are two methods to stealthily kill the globe individual. The easiest is probably to wait until the library is clear of guests and no one's walking by in the hall, then pop the globe and dose the liquor there with poison from your syringe. He'll keel over, and no one will be the wiser. Alternately, you can head upstairs and find the chandelier that overlooks the globe in the library. Placing a charge on its anchor will allow you to detonate it and kill the subject when he passes underneath.

Stove Guy: The easiest of the three to kill, you can take out the Las Vegas Mobster by entering his room, room D, and sabotaging the gas valve on his propane stove. It's best to enter via room A, then head to the balcony and enter via the balcony door to ensure no one sees you. The next time he comes to cook something up, he'll be blown away - literally.

Stove Guy is Rudy Menzana, your primary target, so he's the only one of these three that you really need to kill. You can also take him out by walking upstairs to the western offices, opening the only unlocked door, and stealing the therapist's outfit there. With that on, you'll be able to lure Rudy up into a therapy suite for a little one-on-one counseling, then get behind him and poison him.

Weightlifting Guy: Wait until this guy starts weightlifting, then stand behind him and stand around until he’s almost done setting the weights back onto the bar. At this point, an option should come up to crush him with the bar. If no one is watching you, take advantage of the opportunity to kill him silently; no muss, no fuss.

The Great Escape

Well, not so much. All you have to do to get out of Dodge when Rudy's dead is head down to the morgue, near where you first entered the area. Head inside and revive Agent Smith, then walk over to the exit nearby to escape the level. Done and done!
