If you want to know how to acquire a Keycard from the officer in the Modern Warfare 3 Deep Cover mission, we’ve got you covered! In the Modern Warfare 3 campaign, the Deep Cover mission leans toward a more traditionally structured Call of Duty single-player experience. The mission is mostly linear, and you will have clear tasks. However, if you want to get the MW3 Back in the Field trophy and achievement, you will need to carefully plan out your every step at the start of the mission. Read on as we explain how to acquire the Major’s keycard in “Deep Cover” within 90 seconds without being detected.

How to Acquire a Keycard in Deep Cover Modern Warfare 3

Before we proceed with the guide, it is important to note that this is not a guide for the whole Deep Silver mission. Rather, this guide is here to specifically help you with the MW3 “Back in the Field” trophy and achievement. That is, we explain step by step what you need to do in order to get the Admin Building card. Of course, you will need to do it within 90 seconds of the start of the mission. This is a spy-themed mission where we are infiltrating our enemies undercover. Hence, it is important to note that you need to act naturally and blend in with the soldiers. With that in mind, here are steps you need to do in order to do this in order to acquire a keycard within 90 Seconds without being detected:

1. When the mission starts, run to get behind the approaching vehicle.
2. Run behind the truck’s right side.
3. Stop running immediately when you spot a group of soldiers approaching down the road left of the truck.
4. Take a shortcut via the storage building on the left to reach the admin building quickly. DO NOT RUN!
5. When you enter the admin building yard, go around (behind) the white container office.
6. Enter the white container office via stairs BEFORE the Major.
7. Eliminate the soldier inside and wait for the Major to enter.
8. Assassinate the major the moment he enters the building.
9. Acquire a Keycard from the Major’s body.
10. Enjoy your MW3 Back in the Field trophy and achievement!
