About Sins of a Solar Empire II - Reinforcements
About this DLC
With the conflict between the TEC, Advent and Vasari forces rushing towards a climax, new warships are being called into action. Each sub-faction has deployed dynamic new command ships to help redefine their fleet compositions. These massive new units are deployed from a titan factory and easily dwarf regular capital ships.
Command-Class Ships

TEC Enclave – Takadaran Command Fortress: A massive support platform doubling as a mobile cruiser-scale shipyard, capable of producing TEC cruisers in the field.
-
TEC Primacy – Khevarkov Modular Battleship: A high-speed strike vessel with customizable hardpoints for railguns, missiles, or hangar bays.

Vasari Alliance – Sularkon Tyrant: A city-ship fortress with integrated Phase Gate, designed to lock down entire sectors.
