The rifts show that the world is dynamic, or always changing, and not static like past worlds, Buttler said. When a rift opens, the terrain, buildings, lighting, sky and everything else changes. Players can fight the demons coming out of the rift single-handed, or in a group. The more help you have, the more loot you can collect from the dead bodies when the rift episode is over. But with more people, you have to dispatch the various enemies more quickly to be able to get the loot. So the rifts are likely to draw huge numbers of players to one location. With rifts, there are no safe zones in the game. If a rift opens near a town, you will have to defend that town or lose the safety and resources in that town.
