This time, we will cover the story of Wallace Breen.
In 2001, the Black Mesa Research Facility was operating in secret. Black Mesa was primarily a place for studying portals. The portals they were researching led to the planet Xen, a world filled with high-value minerals and various alien lifeforms. However, one day, an accident during an experiment at Black Mesa caused an interdimensional portal to connect to Earth, allowing countless alien creatures to cross over. Subsequently, a new alien force known as the Combine invaded Earth, conquering the planet in just seven hours.
