Oppressor is the heaviest of T1 ships. It’s biggest advantage is its durable armor and versatility. They are equipped with a powerful long range plasma cannon and a depth charge launcher. Their range allows them to outrange all ships and also torpedo static launchers, which makes them a great choice for pushing the front-line. They are also used as a good counter to submarines. However, due to slow movement and low maneuverability, they can get easily overrun by lighter ships.
It is a good idea to provide them with an escort of lighter ships and repairing support. They are costly and leave very precious wrecks, so take good care of them!
Oppressors have a higher cost, but also higher damage compared to their ARMADA counterpart (Corsair)
