This vessel is actually one of the coolest additions to the Covenant fleet. At first glance it appears to be merely a slightly oversized CCS with spikes. In reality it is an old warship with extremely heavy armor when the Covenant fleet had weak shields. Its described as being not as heavily armed or defended as the CCS. Most interesting of all is that it has a previously unseen system called a stasis enfolder.
I dunno what your guys' plan is for the RCS (or if you were gonna include it at all) but assuming this Stasis enfolder is a larger version of the Stasis cannon on the Vampire. That'd be a pretty neat ability for the Covenant.
"The Stasis Cannon is a Covenant weapon found on the Vampire's frontal section. When fired, it disables the targeted enemy aircraft, rendering it unable to move or fire. Once the Vampire is upgraded with Stasis Drain, the weapon not only stops its target, but also drains its energy regenerating the Vampire itself and making the hostile crash onto the ground. Its second upgrade, Stasis Bomb, causes drained aircraft to explode, inflicting Area Of Effect damage."- halopedia.com
