most of these glitches are pretty self explanatory except for the elevator. so all you have to do is have someone lay next to a wall and hold back and towards the wall on the left thumbstick and you have to be behind them and hold forward and towards the wall on the left thumbstick (this works on any wall without a lip on it. can even be used to get out of some maps). to get inside places just park a vehicle about a foot away from the wall and get out of the vehicle and you should be inside the place. in some places you can shoot through the windows like on eder dam at the bottom of the map. if u need help my gamertag is sharsthooter123
