Maps 15 & 16 Loïc 'Loc' Visse BLOW UP During the Black Mesa Research Facility events, the militaries couldn't clear the sector D secured storage facility with air strikes. So, the high command decided the storm of the facility from the inside. Explosives were carried through the Sector E material transport to sector E, in order to blow up the whole area. However, the mission was a partial failure due to the Aliens Gordon Freeman and the Black Ops. Special thanks to Gearbox's Alpha_Male for the Boot Camp section of Opposing Force, which inspired me to make a similar section in my map.
