The Zthuee combines the best elements of the Aeon Fervor and the UEF Lobo, causing some players to nickname it the "Fobo". It possesses the Lobo's fragmentation shell effect as well as the Fervor's high DPS, much higher than the Lobo or the Cybran Medusa. These traits, combined with the fact that it is one of the few T1 hover units, make it arguably the most powerful T1 artillery piece and one of the Seraphim's best early weapons.
Being a hovering artillery unit, rather than a hovering tank, gives it the advantage of firing over terrain and hills, such as on Haven Reef and The Dark Heart. While Aeon Auroras have difficulty reaching high points from water and cannot outrange point defense, Zthuees can easily fire safely without necessarily having to face unnecessary fire.
However, it is vulnerable to Aeon Auroras and any Frigate when on water. In addition, it is a more expensive unit.
The shell of the Zthuee can occasionally penetrate shields without having to take them down. If the point where the shell bursts into submunitions happens to be close to the surface of the shield, the submunitions materialize inside the shield and continue their trajectory unaffected by the shield (tested in version 3606).
