Depending on the current political situations, some factions may be at war with each other allowing players of opposing factions to fight each other with fewer penalties and even take over opposing factions' worlds. World occupation consists of several hours of combat and hacking that eventually leads to a roughly hour-long final battle for the world, where hundreds of players can be fighting for control. Characters can be permanently killed off if they both run out of clones and Universal Credits to buy new clones.
