Mature Chrysalis
These are the “spawners” that regularly spawns enemy attacking waves. One spawner is chosen at random to spawn the enemies every set period of time. There is a 25% chance that a Mature Chrysalis does not spawn in level. Each Chrysalis destroyed does not strengthen the enemy spawns nor increase the spawn frequency. In some levels you have to destroy some bigger buildings like Overmind Cocoon and Psi Disrupter in order to disable the Chrysalis' invincibility.
