Not to be confused with Trial, which is popularly dubbed as Raid.
Raid missions required the player to find an artifact, loot it, and return to extraction. Players will get a random mod, blueprint or consumable as a mission reward on completion of a Raid mission. Unlike items picked up from enemies, the reward item has its card's picture on it in the mission summary screen.
Although Raid missions are officially removed, it is still possible to get this mission as secondary objective, along with the artifact drop rate.
