In the single-player campaign, your journey begins within The Tower—a central hub and humanity's last bastion against the Astral Gods. Step through the portal into ever-shifting, treacherous biomes where the environment is both your playground and your impending tomb. The longer you survive, the more aggressive the shadows become, forcing you to battle through hordes of Zombies, Skeleton Archers, and massive Ogres. Fight your way to the exit portal to live another day, or risk everything to slay the biome's Boss and claim final victory over the gods themselves.
