Matriarch

The Matriarch is the final boss and most powerful enemy in the game. She appears as a floating stone head, with two stone fists resting on the ground beside her.

The Matriarch, once you have entered her room, will create a pattern that you will have to remember by lighting up pads on the ground. You will have to step on them in the pattern given. If you step on them in the correct order, then she will turn red, and you will be able to damage her. If not, than she will laugh at you, and then either throw Headcrabs at you, spawn in enemies, or smash the two fists together at you. It will throw 4 Headcrabs at you in normal mode. When it spawns an enemy, it lifts up its hands, revealing 1 enemy under each hand in normal mode, and 2 under each hand in hard mode If you get hit by the fists, it will deal 20 damage to you. It will repeat all of this until you deal enough damage to it, to finally kill it.
