HiddenCoordinates is a project made by me, where I'll be showing you different spots, secret rooms or even wallbreach on each maps. Let's start with Combine, because it's my favorite map. I also plan on creating a tool that will give you the possibility to teleport yourself to these locations as well in the future.
