Storyline

After years of alien rule, humanity won the war for Earth. But when the Overlords fled the planet, they left their former soldiers behind. Now, five years after the events of XCOM 2, humans and aliens are working together to forge a civilization of cooperation and coexistence. Welcome to City 31, a model of peace in a post-invasion world. However, not all of Earth's inhabitants support interspecies alliance. Chimera Squad, an elite force of human and alien agents, must work together to destroy the underground threats driving the city toward chaos. Your agents are unique: each of them equipped with special tactical abilities and driven by a different motivation for joining Chimera Squad. Deploy targeted team members to investigate and combat the dangers that pervade the districts of City 31. Lead Chimera Squad through a new experience that innovates on XCOM's turn-based legacy, utilizing strategy, teamwork, and new breach-and-clear gameplay to complete your mission objectives. The future of City 31 depends on you.
