It's just another normal day at the Black Mesa Research Facility. You enter the facility and are on your way to your assignment when suddenly there is an odd change of events. A resonance cascade has occurred, and your only hope is to find a place to hold out until rescue arrives. Luckily, you meet a group of scientists who have survived and are holding out in their own hideout. They inform you of an undercover mission by the government to use this disaster as an opportunity to sneakily gain access to Sector F, the Lambda Complex, in hopes of manipulating the teleportation technology that was developed there. Since you are the one with the hazard suit, you are sent on a mission by these scientists to counter these government "black ops" and prevent them from gaining access to the main teleportation facilities of the Lambda Complex. However, getting to Sector F will not be as easy as it may seem. This mod aims to resemble Half-Life in various aspects, while also presenting new content.
