Pipedream is an Atrium based 2v2 map that draws visual inspiration from Countdown in its simplistic concrete aesthetic.
In CTF and strongholds the shotgun replaces the SMGs.
To download the map just add my gamertag; "One Nut McGoo"
Edit - 2/25/2016: I have updated the map to support all "ball" gametypes such as bomb and oddball. I have also removed the boltshot and splinter nade from the map.
