This guide will provide you with all Safe locations and their combinations in the Modern Warfare 2 campaign.
There are a total of three safe locations that you can find in Modern Warfare 2’s Campaign. To find the first safe, you have to go halfway through the campaign in the El Sin Nombre mission and then head upstairs to the El Sin Nombre mansion.
Move through the window and head down the hall from the bedroom. You will get into another bedroom with an openable cupboard holding a safe. You have to enter the code 02-02-19 to open the safe and you will get a Lockwood 300 shotgun and a plate carrier.
The next safe is located in the Alone mission. You need to open up the door that’s getting beat on by the guy. After that, use your knife to open up the door on the left side. You will find a safe inside this room and the code to open this safe is 10-10-80. You will get the Silenced Deagle and a throwing knife from this safe.
After that, drop down through a hole in the floor and you will get into a red-tiled floored building. Exit it by taking a left and entering an adjacent car garage. Head into the corner office and open the third safe with the code 37-60-80.
You will get the crossbow from that safe that you can use to take the enemies down. You will also get that Gentleman Thief trophy.
