The earliest iteration of the next WildStar prime raid has worked its way on to the game's PTR. The Genetic Archives Prime Level 1 is ready for testing and will be released later in 2017. The team is looking for groups of players to assist with focused testing events. Devs are asking interested groups to reply to the thread on the forum with times they might consider lending a hand.
Prime Raids begin at Prime Level 1 that are similar to existing raid progression, but with a twist. Each raid and Prime Level beyond 1 increases the challenges and rewards over "normal" raiding. Prime Level 1 raid dungeons can become even more challenging for the brave of heart by adding the Hard Mode designation on top of it. This buffs boss health and damage and includes new mechanics. This raises the number of difficulty levels for any given raid to normal, Prime Level 1, Hard Mode and Prime Level 1 Hard Mode. Of course, great risk means great reward. The more difficult the encounter, the better gear and item drops players have a chance to earn.
