Too Big to Fail
How to unlock: You need to complete Gilded Cage in Marrakesh.
Comment: You will unlock the achievement, regardless of the methods you choose to assassinate Claus Hugo Strandberg and Reza Zaydan.
50 Personal Touch
How to unlock: You need to kill Zaydan as a prisoner, Strandberg during the massage, and both of them with a .50 caliber gun.
Comment: This achievement depends on eliminating Claus Hugo Strandberg and Reza Zaydan using different methods. The prisoner is in the school and once you "take over his identity" you can eliminate Zaydan once he enters the torture room. Disguise yourself as the masseur to assassinate Strandberg in the embassy. To kill both of them, you can use the gun attached to the APC vehicle. Just wait for your targets to meet at the courtyard by the school. All the methods were described in the chapter devoted to the mission in Marrakesh.
How to unlock: Give coins to one of the beggars.
Comment: Beggars can be found in the main market (its location is presented in the screenshot). In order to complete this unusual achievement, you need to give a beggar 5 coins - make sure that they land on the plate in front of him. Bring coins with you, so that you start the mission with 3 of them. You can find the 2 missing coins by exploring the map. You can find them e.g. on the counter in the shoe shop. (M5.25) - at the back of the shop, there is a tunnel that connects the market and the embassy.
How to unlock: You need to use all the opportunities available in Marrakesh.
Comment: Use all the opportunities to eliminate your targets. You can go through their list by pausing your game and selecting the right tab. It is obvious that you cannot complete all of them in a single gameplay. You need to play Marrakesh several times and each time you should focus on one specific opportunity (maybe two if they are related to different targets and do not exclude one another). Tips on how to eliminate main targets were presented in the walkthrough.
How to unlock: Complete the fifth level of escalation in Marrakesh.
Comment: With each escalation, Agent 47 will face more and more complex challenges related to assassinations. Marrakesh offers several escalations, and in order to unlock this achievement, you need to complete one of them.
How to unlock: You need to select an alternative starting point in Marrakesh and use the Agency to help you smuggle something to the area.
Comment: Both options will become available once you reach higher ranks. Try to complete Marrakesh mission on "regular rules" at least once, before you decide to choose the starting point and use equipment delivery.
How to unlock: You need to reach the 20th rank in Marrakesh.
Comment: You can advance to higher ranks by completing different challenges related to the Marrakesh mission. This includes eliminating main targets using various methods, finding unique items that may come in handy during assassinations, or beginning the mission in from different starting points. You don't have to complete all the available achievements to reach rank 20 (the game informs you on your progress after you complete a mission), so start with achievement that you find most interesting.
