"Counter Strike: Global Offensive" is the modern version of the PC classic "Counter Strike." The game allows its players to create and upload stickers that can be placed on a player's weapon.
The process involves knowledge of working in RBG channels to create a holographic effect and working in normals to create height maps for embossed stickers. The sticker can then be told how it will "wear away" using an Alpha Channel.
