The images in this guide are "Call-Out" spots on all current CS:GO competitive maps. These "Call-Outs" are used to communicate with your team where you are, where the enemy is, where the bomb is planted, and anything else that will help you win.
Please keep in mind that these call-outs will vary by region, team, and version of CS. It's OK to have different call-outs from what you see here. These are not some "standard", they are just very common. Hopefully people use them universally so we can all communicate better in matchmaking.
I want to thank Nik for creating this concept and design, showing it to me, and letting me run with it. Apex will always be the greatest map ever created.
