Hello Gordon, and welcome to your last day at the Black Mesa Research Facility. A cloning experiment has gone awry and you find yourself in the Black Mesa you know, but it isn't the Black Mesa you know! Dr. Coomer and his clones have gone and made a muck of things and it's up to you to find enough PlayCoins to appease them!
