Against the opposing faction
Also, when I talk about star trek I am only going to talk about the Elysian part since that is the faction I play. In star trek credits you can experience the PVP part in PVP servers by killing the opposing faction players in the world or by going Battle Grounds or Arenas. While in star trek you can kill the opposing faction by going in a rift which has limited time and number of entries or by going to the Abyss. You can also participate in Fortress Sieges against the opposing faction or the neutral Balaur race.
