Players encounter a symbiote. Whether it helps or fully controls the player is random, while symbiotes descend from the sky, fungal roosts uprise and start taking over villages, then slowly start infecting the world around it. Trying to stave off the incoming symbiotes to defend this world against its rule, the player is tasked with learning how to befriend the chosen symbiote while defending themselves from the infection trying to wipe them both from this world.
