Everyone says how gordon or adrian were unprepared, but gordon has a mini-mech suit, and adrian has military training. Barney had nothing, and traversed xen before any of the others, and just waltzed out like a goddamn madman. Then in half life 2, we clearly see that after the time jump, barney has taken control of the resistance, and singehandedly did 82% of the resistances goals. Barney is him.
2:49 In Half Life 2 Lore; Gordon understands their suffering when he goes through the city for the first time and when he is asked to pick up the can. That is why he puts them all to sleep.

5:15 why yes actually, I did play opposing force today! I just learned that if you use the cheat "impulse 101" it not only gives you every weapon in opposing force, it also gives you every weapon in base Half-Life.

The security officer for some reason said to me "Hey, what did I ever do to you?" Like, WHAT?
