I remember X Death messaged me that Real War is now again approved a pretty good map its just people camping everywhere forcing the other team to go offense taking over the water is my tactics as it slows bullets down making it easier for me to kill those campers
Anyways you can try and experiment on map making if you don't know how it works you can ask a experienced map maker to teach you. Copying is bad but you are new to map making so study well and welcome to map making world.
