"Gordon refused to cooperate with the G-man. The employers thought long and hard about whether to return the agent to stasis or to get rid of him once and for all, but the G-man had his own plan of action.

He traveled with Gordon to another temporal reality, where humanity had lost to the Alliance, but the Alliance itself had failed to enslave the world of Xen, from which various creatures had begun to emerge, turning part of the city into a slum. Freeman's task was quite simple - to prove to the Employers that he was still a valuable asset. He was separated from the end of the task by a kind of essence, a generation of energy that could easily lift heavy objects into the air and use them as a shield or weapon.

A wounded and tired scientist in an armored suit with a crowbar against an unknown entity is a repeatable fragment of Freeman's story."
