There is a weapon skin I want to use in Counter-Strike: Global Offensive called Pulse. I cannot figure out how to add it to the game. It says "considered for use pending" if this helps.
Counter-Strike: Global Offensive's workshop works differently than most Steam workshops. You cannot simply browse to a file and add it to your game. Instead, the workshop is used to see items that maybe added to the game as drops or a part of a weapon case, or ones that have already been added.
Once you acquire the weapon (that particular one is already in the game and can be found by opening a winter offensive weapon case), you can use it by going to your inventory in-game and replacing your current weapon with the new one by right-clicking on it and choosing "Replace T", "Replace CT" or "Replace both".
