Me and a friend have created an arena style competitive 1 v 1 map that is symmetrical and cover gradually spawns in through the game. I Believe the map we have created is very unique and others would definitely benefit from playing it. Example using it to warm up before playing as its much better than playing something like octogon as it introduces the use of cover.
we would greatly appreciate it if you could check it out and give us some feedback
