I listened to enough dev comentaries in-game to know that valve loves to reuse their old concepts for half life games
So what if half life 3 presented gordon with the choice to destroy the borealis or use it against the combine and face any consequent consequences
(just like how gordon in hl1 was given a “decision” to accept GMAN’s job offering, or succome to a mass Agrunt rape)
the alledged [color=lime]return to xen may foreshadow such a returning concept. But it is still unknown if gordon will assault the overworld from xen or just have a lone battle with whatever he has to encounter (from what i seen in the concept art leak on the day of Meet the pyro, there is somthing else gordon will encounter either far worse than advisors or somthing higher up in the combine; or maybe the advisor’s final form in metamorphesus, as it is a larva creature)
