The game takes place in a fictional universe on the recently discovered planet of Nexus. The planet, once inhabited by a hyper-advanced race of aliens known as The Eldan who has all but disappeared, is fought over by two factions both hoping to control the concealed lost technology of Nexus; The Dominion, an intergalactic empire which decides that the planet belongs to them, and that it should be explored to discover the lost technology, and The Exiles, a group of refugees and outlaws who have all been driven from their respective homelands by The Dominion and have joined forces to fight them.
In WildStar, players are able to create a character that they can control through their playing session. These characters can move in an open, persistent world environment. Characters can level from 1 to 50. Gameplay mainly consists of quests, dungeons, and player versus player combat.
