The Sentinel Mk4 is a brutal heavy mothership. Spawning fast attack orbs from its top platforms makes the Mk4 a serious enemy for even the best of pilots. 

Its steady barrage of attack orbs gives the Mk4 an excellent defence while at close quarters the ship its self is very weak. While its strong defenders try to keep you at bay, dropping Smart Bombs in the right position will deal a serious blow to the Mk4.
