Relentless Nexus Survival Mod tests your base defenses by summoning waves of hostile invaders. Monsters in this mod do not just wander around; they dig through walls, construct bridges, and break blocks to reach your central core. You place a Nexus block, activate it with a catalyst, and fight off increasingly difficult hordes to protect your base.
