Wave Brain

The survival wave director from Manstrosities. Runs escalating waves of hostile mobs from an out-of-sight spawn ring, schedules rare aerial threats (Tithewing pack-drainer, Severer bond-breaker), and erupts a rotating colossus (boss with entrance/slam/leap patterns) at milestone waves. Sweeps far wanderers, pushes per-player fps into a run-wide perf tier for mixed-device co-op, and governs co-op threat scaling with MHMind — elite scaling to group size, hardest-difficulty-wins pause math, and a shared ceasefire when any survivor pauses. Ships as a data-driven brain: a roster JSON supplies which creature ids to draw from at which wave and which colossi rotate at which milestones. The seam to a creature system is a spawn-by-string path, so a new game points it at its own creature behaviors or at the paired creature-engine mod.
