* Based on a tower defense mobile game developed by Chinese developer Hypergryph. After Reunion is routed and Lungmen secured, Kal'tsit delivers grim news to those gathered in Wei Yenwu's office—Talulah has detached the core city plate of Chernobog and set it on a direct course toward Lungmen. Making matters worse, Chernobog is still officially an Ursus city. If the two nomadic cities collide or engage in open conflict, it could ignite a catastrophic war between Ursus and Yan—a war neither nation can afford. In the meantime, the Doctor brings FrostNova's corpse to Rhodes Island's bioprocessing unit and meets Rosmontis. Source: Arknights Terra Wiki
