Ghost At The Feast (DEATHLOOP) - Quick & EASY

Most guides suggest weird ways to reach the party and they want to use the meatgrinder...needing much too much time, which is not the best if you have to try again the level in case you fail, a lot of time wasted because somebody spots you or you miss a kill. This way is very quick and easy and has very little room for error. To avoid Julianna, set to friends only (and don't let them invade, or just don't have any friends).
