How Valve Should Make Half-Life 3
3. Put The Central Focus On G-Man And The Combine Advisors
The mystery of the elusive G-Man is a component of the Half Life franchise that has made it resonate from players right from the get-go. He caused the resonance cascade in the original Half Life by delivering the fated sample, placed Gordon Freemen in stasis and has always influenced actions and consequences in some shape or form.
We now know that this strange individual has both employers and foes far beyond his reach and abilities. If G-Man is the acting agent, then who are the real masterminds behind the series conflicts? He should play a much greater role in Half Life 3, his presence lingering over Gorden throughout the game. Will we get to challenge him directly? There's certainly a possibility, as the ending of Half Life: Alyx suggests.
Equally intriguing are the Combine advisors; these creepy, slug-looking things are the hive minds of the alien race, possessing great telepathic abilities. With the cowardly Dr Breen as their puppet, they were the masterminds of the takeover of Earth through Half Life 2 and escaped the collapsing city at the end of Episode One.
Players came face-to-face with them in episode 2, as one brutally extracted the brain contents of a dead resistance fighter. More are still running loose in the deadly landscape and there's so much behind these creatures that remains unknown.
Tying them with both the G-Man, the lost ship B and the greater interdimensional nudges at play would make for the most absorbing story of the entire series.
