+Pocket turrets that shoot at any enemies standing in front of them. Easy to

+Unlike the Light Sentries this one has a much wider range of view and can be
+resupplied with extra ammo. Conveniently, you can also recall it to put it back
+in your inventory. While carried it will slowly repair any damage it has taken.
