Alekhine's Gun

Throughout the game you will come across various locked doors and windows. This achievement only unlocks if you successfully lockpick a lock with four or more mechanisms. This can first be unlocked in Level 5, ‘Angels in Texas.’

At the beginning of the level, you need to sneak into the house. Make your way around to the left side of the house, through a white fence then climb up onto the roof. When you get up there, pass through a window on the left where you will see a hole in the floor to the level below. Wait for the guard to move then climb down the ladder. With the guard’s back to you, walk to the staircase on the left and when you are at the bottom, turn around and there will be a closed door in front of you.

At this point, pause the game and “Save Game.” When you open the door, sometimes there is a guard walking back and forth in the corridor. Press to open the map to see where the guard is; if he’s to the right standing still then you’re safe, and if he’s patrolling, wait until he’s finished his route before you continue. When it’s safe, proceed through the door and to the left.

There is a door in front of you and one to the left. The left door is the one we are going to lockpick. Press to initiate the lockpicking mini-game and match up the four mechanisms. If you make a mistake, just press to back out and try again. Upon successfully unlocking the door without making a mistake will unlock the achievement.
