Rogue Warrior

S.N.A.F.U. (Situation Normal: All Fucked Up) is the first mission in Rogue Warrior. As the three difficulty achievements don't stack you may as well do this achievement (along with all the other mission completion achievements) on Recruits (Easy) difficulty.

After the opening cutscene you will find yourself in a river bed armed with your knife, a silenced pistol (Sap9) and a Submachine Gun (SM5). Crouch and proceed forward down the river bed. When you see a street light with a flickering bulb exit the river bed, move up behind the first enemy and follow the prompt to perform a Kill Move. Proceed along the path and up the stairs into a guard hut, wait until the enemy is peering through the window and then move behind the enemy and perform another kill move, this should earn you the Not The Face achievement.

Crouch, exit the guard hut and you will see two enemies facing away from you, sneak behind them and perform kill moves on both of them (the game will prompt you to zoom, however it is easier to just use the kill moves). Carry on down the road and you will see a doorway to your left, enter this doorway, crouch and immediately turn right and head up the stairs. As you reach the top of the stairs you will see a shadow move to the right and be prompted to shoot the fusebox, ignore the prompt, take down the enemy from behind with a kill move and then shoot the fuse box. Continue up the next flight of stairs and again perform a kill move on the enemy at the top. Turn left, head down the corridor and perform another kill move, you should now unlock the Ninja achievement.

Open the door, sneak through the door way ahead of you, turn right, head to the end of the room and then turn left. Wait until the enemy is leaning on the window sill and then perform a kill move to unlock the Over The Top achievement.

Swap your pistol for the sniper rifle (Dragunov) leaning against the desk to your right and use it to snipe the three guards patrolling the yard below. Use the rope in the window to rappel down to the yard and swap the Dragunov for the assault rifle (AK74) dropped by the guard you've just thrown out of the window. Move towards the doorway at the far end of the yard and throw a grenade as soon as you reach the bottom of the stairs (if you're lucky this will earn you the Gang-Bang achievement), use the AK74 to finish off any guards that survived the blast from the grenade.

Enter the building, turn right and be ready for two more guards to burst through the door at the end of the hallway. After mowing these down with a few quick bursts from the AK74 crouch and take cover in the doorway and throw a grenade into the alley. A well aimed grenade here can blow up the two cars next to the fence and the resulting explosion should kill both of the guards, if not move out of cover and finish them off with the AK74.

Enter the building at the end of the alley, restock on grenades and swap your AK74 for the shotgun (Type 97-1). Open the door, move to the end of the corridor and blast the enemy with your newly acquired shotgun, turn left and take down the guard hiding on your right. At the end of the corridor another guard is hiding on the left, immediately after taking him down spin around 180-degrees and blast the guard hiding on your right. Open the door and there is another guard hiding on your right, blast him and you should unlock the Come Get Some! achievement. Proceed down the hallway, blast the guard at the end and then quickly turn and blast another enemy coming out of a room to your right.

Move up the stairs and blast the guard halfway up then be ready for another to burst out of the door on the left of the first landing. Move into this room, take any grenades you need then continue up the stairs. When you get to the next landing turn left and then right towards the open door before the barricade, throw a grenade into this room to take out both of the enemies taking cover behind the sofa and proceed onto the balcony on the far side of the room, turn left as you exit the room and kill the guard on the balcony. Turn left into the next room and take down the two guards in here. As you enter the hall another enemy will burst through the door ahead of you so be ready to take him down. Turn right, deal with the guard hiding on the right hand side of the hallway and then enter the room on the left.

Move through the broken wall and as you turn right and move into the next room the far wall will explode. Throw a grenade through the new opening and then move back around the corner. Once the grenade has gone off (giving you another chance to earn the Gang-Bang achievement) move back into the room and finish off any remaining enemies. Exit the room on the right, move through the door across the hall and blast the final guard of the level. As soon as he goes down a cutscene will start and you will earn the SNAFU achievement. If you completed the mission without dying you will also earn the Dick Would Be Proud achievement.
