Titan Boss

The third boss. It is intended for beginners and spawns in the new and old wave system.
There are two wave systems: the new wave system and the old wave system. In the new wave system, every 10 waves has a boss up until wave 190; after that, only zombies spawn. In the old wave system, bosses initially appear every 10 waves, but they spawn less frequently after wave 50. Wave 1000 contains the final boss.”
