I have a theory for half life 3 involving appertures portal technology.
I beleive the G-Man has always used the Portal Gun in order to be one step ahead of Gordon throughout the half-life series. If you play through the games throughly or perhaps with cheats you should notice the G-Mans continual reappearence throughout the games.
Adrian Shepherd is due to make his return, Adrian also being apart of G-Mans ‘property’
Adrian Shepherd from Opposing Force infact had a basic version of the Portal Gun, only he could send enemies or himself into the Xen world with it or if already in the Xen world bonus Earth Locations were visitable if Ammo permitted.
I believe this is why G-Man was after him and helped him during early game.
I believe G-man wants or already has the apperture portal weapon and will use either Freeman, Shell or Adrian to get it for him, or to work for him with it.
It would be interesting to play as G-Man with nothing but the Portal Gun and perhaps a Time Lapse Devise. All of G-Mans secret scenes and Easteregg locations throughout the series could be made sense of, Every time the G-man helped or guided any of the Half Life Characters these events could be taken into account and perhaps played through on a time-lapse basis from the perspective of G-man, Perhaps all jumbled up and confusing but nevertheless the sense could still be made from it after repeated sessions, This could help solidify every episode of the series as G-man guides the events which eventually shape his future in bringin down the Combine and becoming the supreme commander of the Universe perhaps with Adrian Shepherd as an Inside man.
Anyway Besides the Point, I want to hear your thoughts. My opinion in one line is that G-Man has always used the Portal Gun to be one step ahead of Gordon, Adrian Shepherd, The Vortigons etc and i do expect to see the Portal Gun in half-life 3, only perhaps not for the characters we’d might expect.
For the Record, half life 3 is not confirmed but it is an inevitability due to the cliff hangers they leave us on. Nobody ever expected a half life 2 but it still came.
