It's been nearly 15 years since the release of Half-Life. Some have been pretty hilarious, some not so much, but all have been saddening. Gordon Freeman must fight his way out of a secret research facility after a teleportation experiment goes disastrously wrong. It ties into plot threads brought up in the later Half-Life games such as Half-Life 2: Episode Two, such as The G-Man being responsible for delivering the Xen crystal sample and starting the incident.
The player takes control of a scientist simply known as 'Subject 12' and his perspective of the Black Mesa Incident.
