Call Of Duty: Modern Warfare – Wall Hax Achievement & Trophy Guide
“Wall Hax” Achievement & Trophy
In Mission 5: Clean House, Alpha 3-2 is the codename of one of your teammates called “Sgt. Madden”. In this mission, you will go through a dark house and must shoot all the enemies hiding behind doors. When you go up the stairs to the second floor, there will be a door on the right side. You must shoot through this door before your teammates walk past it to expose the enemies behind the door. Kill all enemies in the room behind the door and go through all the rooms. Once you move on to the third floor, you will get the “Wall Hax” achievement. Normally, if you did not shoot through that door, the enemies would shoot through it when Sgt. Madden (Alpha 3-2) walks behind it, and he would get downed. Note: It is easier to do this during mission replay once you are familiar with the mission layout.
