Half-Life has a story up clarifying that Portal in Half-Life 2: Episode Two
is a separate game from Half-Life 2 that does not exist within the Half-Life
continuity (thanks
Ant). This strikes us as how the project was described from
the get-go, but in case there was any confusion, they distill a couple of recent
interviews to clarify the situation:
With Portal co-existing in a world
along with Half-Life, crossovers are a definite possibility. Unfortunately,
according to Kim Swift, we won't be seeing any Portal gun versus Gravity gun
duels in the foreseeable future. Rumors surrounding the device's name, "Aperture
Science Handheld Portal Device" suggested the return of another Half-Life
character, Adrian Shephard. Adrian, the central character to Opposing Force,
meets a similar fate to Gordon Freeman under the G-Man. Though the sequel to
Half-Life continues Gordon's story, the whereabouts and condition of Adrian is
still relatively unknown.
