Artificial Insanity Gameplay

This is a game demo I've been working on recently (I guess it's complete now). It's called Artificial Insanity, and was made with Unity. This game follows the mission of a robot with human-like capabilities. When humans discovered a strange portal artifact deep underground, they began to study and perform experiments on it. One study turned ugly, disrupting the artifact and opening up a portal between the underworld and Earth. Strange creatures and the living dead began invading the facility. To protect themselves, humans created the first generation of protection robots (red). It worked for some time, keeping the creatures at bay. However, another artifact disruption corrupted the protection robots, making them kill everything in their path. One scientist managed to escape, using the facility's state-of-the-art space cruiser; landing himself in Earth's orbit. On the space cruiser, the scientist built a new robot, capable of defending itself and destroying the artifact (the player). Let me know what you think! It's not a full game by any means, but a showcase/demo of what could be.
