You are Adrian Shepard. Trapped inbetween worlds, where time does not exist, forgotten by the G-man you now wander your past, reliving events of the Black Mesa incident over and over again.
A few updates have been made to the second map in the game, it felts a little sparce so I've added more geometry, enemies, decals and generally more detail to make it feel like there was a battle here.
I'd enlarge the whole complex so that you gain additional space and make the streets rounded up instead of going through corners and edges.
