Defiance raiders aren't all about getting epic loot and counting DKP, they're about bursting onto the scene in a spray of automatic weapon fire while tripping on a variety of drugs. And the newest video for the game shows the raiders off in all their glory.
As the video explains, raiders are an ever-present threat due to their sheer inability to be wiped out -- they have no centralized structure, just a large number of members who enjoy violence and follow whoever wants to lead. Players are advised to either use explosives on groups or snipe individuals at a distance. For more details on this group of enemies, take a look at the full video just past the break, and possibly apply more DOTs.
