Plot
In, , South Korean theoretical physicist Park Dae-jung arrives late for work at the Kershner Research Facility. As part of an experiment, he pushes an unusual material into a machine, called the anti-mass spectrometer, for analysis. The spectrometer explodes, creating a "resonance cascade" that severely damages the facility and opens a portal to another dimension, Xen. Surviving scientists urge Park to head to the surface, where he defends himself against hostile Xen creatures and the HECU (Hazardous Environment Combat Unit), a special unit of United States Marines sent to cover up the incident by killing all of the hostile aliens and any Kershner personnel they find.

Heading to the surface, Park learns that scientists from the Lambda Complex may have found a way to close the portal. Park travels to the other end of the facility to assist them. Along the way, he activates a rocket engine test facility to destroy a giant tentacled creature and uses a disused railway system to reach and launch a satellite rocket. After he is captured by the Marines and left for dead in a garbage compactor, he escapes and makes his way to an older part of the facility. There, he discovers Xen specimens collected before the incident. Overwhelmed by the alien forces, the HECU Marines pull out of Kershner and begin airstrikes. Scaling cliffs, navigating destroyed buildings, and traversing through underground water channels, Park arrives at the Lambda Complex, where scientists learn the portal is being forced open on the other side by a mighty entity. They have developed teleportation technology that allows Park to travel to Xen, where he is tasked to stop the entity.

In Xen, Park encounters the remains of researchers who ventured there before him and Park defeats the Hunteor, a huge egg-laying headcrab. At a factory creating alien soldiers, he enters a portal that sends him to a vast cave. There, Park confronts the Manippiam, the entity maintaining the rift, and destroys it. Park is summoned by the mysterious G-Man, who has been watching his progress in Kershner and praises him. The G-Man explains his "employers" wish to employ Park. When Park accepts, the G-Man congratulates him and places him into stasis to await his next assignment.
