After centuries of defending Earth from an endless war, the android soldiers of YoRHa believed their mission to protect humanity had reached its bitter end. But when the Militia from the Frontier arrives on the long-lost planet of Earth, they offer YoRHa a second chance-not to fight, but to live. As Commander White, 2B, A2, and their fellow androids struggle to adapt to civilian life on the Militia's homeworld of Harmony, bonds of trust and understanding are forged between two civilizations shaped by war. However, new challenges arise as remnants of their pasts threaten to disrupt the fragile peace. Together, the Militia and YoRHa must navigate a path toward unity, redemption, and a shared future. In this epic crossover of Titanfall and NieR: Automata, the fate of humanity-and its protectors-hangs in the balance.
