"Nether is a fast-paced survival game that forces you to make quick life-saving decisions in an unforgiving environment. In this post-apocalyptic urban world, death is waiting around every corner, at the top of high-rise buildings, and in the grasp of powerful teleporting creatures known as 'Nethers'. These creatures and the other players are real challenges to overcome, requiring tactical gameplay, awareness, stealth, and cooperation. To navigate this high-tension environment, you must use skill and cunning in order to scavenge, trade, craft or loot for food, weapons, supplies, and other resources necessary to stay alive in a desolate and dangerous city. Team up with other survivors and take advantage of group play, as a tribe, to complete treacherous world objectives, or play as a lone wolf in an attempt to endure the hostile environment. In the end you must decide whether to Prey or Pray."
