When the day arrives of Blizzard making an Overwatch editor, I'm probably gonna have to redo this map. Not to mention the lore of Overwatch will probably destroy this concept... BUT I'm gonna try to finish this before they ruin that.
I'm not totally sure what to call this place yet but I will share my quick little doc that I made that will explain the story and more. For what I will show right now is that it is a payload to capture point and the setting is on the moon.
Hopefully I can work with my buddy to realize this Overwatch map properly. We'll be doing this in Unreal (or if Blizzard is reading this... their editor!!). I'll show more soon. Once I stop playing so much Monster Hunter!!
