The follow achievement were going to look at today is the Partied out achievement in order to do this we need to complete three challenges they are, Tremain has a rifle accident, Thames is hit by a crane and Montgomery & Banner light up the club.
From the start of the video immediately get frisked by the guard walk through the hallway into the staff only area and up the stairs. As you climb the straights and go through the door take a right, and then climb up the wall DON'T go up the ladder run to the left of the wall continue straight and then climb the ladder on your right.
Sneak up to the guard and subdue him drag him into a hiding spot and then take his clothes, This will allow us to walk around ALMOST freely. Walk towards the two guards patrolling don't make eye contact just keep running forward. take a left up the stairs make a right going across the bridge connecting both of the buildings.
go up the stairs onto the roof and take a right go to the other side of the roof you will see a staircase start walking down it and wait on the other side of the door, Your waiting for the patrolling guard to go to the right side of the building you want to go in and subdue him. Turn around you will see your target and the rifle go sneak up to the gun pick it up and shoot your target.
Were going to want to go back onto the roof back across the bridge down the stairs on your left then take another left. Inside the building is a stair case you need to go down the stairs to Level 0. Walk past the guard towards the toilet and then take a left. again walking forward past the night club staff member taking another left. On top of the boxes next to the stair lift is a fuse pick this up.
Run back to way you came and instead of going to the staircase take a left and go through the exit. take a left once your outside run towards the crane. place the fuse in the fuse box and climb the ladder. you only have one opportunity to kill your target wait for him to walk over and interact and drop the pipe.
Climb down the crane and walk back inside the building. Run straight on and at the end of the hallway take a right and go down the stairs. at the bottom of the stairs take a left into the bar and go behind the left hand side and again taking a right into the backstage area. On the right is a fuse box turn it on and we need to pacify the man who comes to turn it off. Hide his body and then do the same to attract the female.
Once the bodies are out of the way pick up a screwdriver that both the Tech members drop and sabotage the box make sure you pick up the mans clothing and make your way to the opposite side of the room down the stairs onto level -2
Take a left at the bottom of the stairs and through the door you will see a DJ eating you need to turn on the rack case. this will lure over the DJ make sure we subdue and take his clothing and put his body in the box behind you. Make your way into the DJ booth and dismiss the current DJ.
Keep hyping up the crowd and wait for both the targets to come onto the balcony once they have both stepped on the balcony about overload the climax of the light show and you will kill both the targets. This will pop the achievement bare in mind you will still need to kill one more target and then escape to complete the mission.
