And you got it!!

Half-Count was built from a theory of what a head-to-head map on Countdown would look like, I've added in safe zones and kill zones to section off the top floor including the bridge where an Active Camo spawns, the Grav lift area is also included, accessed by a teleporter. Inside players will find a shotgun one of two power weapons. Methods for travel into the lower sections of the map have been blocked in every way, two teleporters near the lifts have been added, these lead to one another while a teleporter in the middle leads to the aforementioned lift room. A Grenade Launcher is located on the outside terrace of the map with only one clip, which means you get one chance to land a shot, that's it.
When playing on teams you can play stockpile with Red and Blue.
It's still recommended to only play with two players.
