Extra Terrestrial Nation

Extra Terrestrial Nation is a visual novel set in 2045, after humanity discovers proof of extraterrestrial life within our solar system. You play as Nicole and later as Rocky, fighting through dangerous streets and other places in a city overrun by extraterrestrials.

The extraterrestrials act on primal animal instincts and are out for blood. You are trapped in their zoo, a research facility, and must navigate encounters with them and other people as you try to survive and escape. Nicole meets Rocky later in the story, but whether he can be trusted is uncertain.
