The covenant sentry turret is an anti-infantry tool used to take out marines, ODSTs, and Spartans. It is a combination of a shade turret and a plasma grenade cannon. This creation was a good plan because it used little resources, and didn't use any pilots. I made this using probably 95% mega bloks. I also used, of course a shade turret and some parts of the banshee 2016 set. But the first and second picture is it turned off and the third to fifth pics are it turned on, the turret also has a weak point on the top as seen in pics 4 & 5.
