The problem for that strategy with this map is control. You can't activate the shield and camp for more than a few seconds - one minute at the very most. In order to effectively shotgun camp in there you need to: -Secure the shotgun -Hold the middle -Have a teammate constantly cycle the shield -dodge return fire between shield deployments That sounds like map control to me. I love how 343i are using one of my favorite maps, Zanzibar, as inspiration for a lot of their maps.
