In Citizen Zero, you must complete private space missions that provide intense challenges for you and your team. You play a prisoner-turned-mercenary on a penal colony in crisis. As you travel the dangerous wilderness in search of rare resources, you can stop guards from sounding alarms, draw enemies into ambushes, and use multicharacter combos to deliver powerful attacks. Take on high-level missions and battles to advance your clan, upgrade the clan HQ, build alliances with the factions, and unlock special content for the members.
