SotSS is a 4x/RTS mod based on the Universe of Freelancer/Starlancer
Liberty's primary Very Heavy Fighter is the large and powerful Upholder.
Armed with three Plasma Cannons and two Nuclear Torpedo Launchers, it can make short work of most capital ships as long as they have some cover.
Heavy and Light Fighters will outclass the Upholder due to their maneuverability.
Upholders wont even manage to hit fast moving light fighters with their plasma cannons, and the torpedoes cant get a lock on anything other than capital ships and orbital stations.
