OK, first pic, just for kicks



and now...
some REAL guy....
who is the twin of GFreeman



and now, form the book Half-Life 2;Raising The Bar




and aparently, Nihilanth talked to Gordon... hmm... combines existed since HL1 (and these wristbands Nihilanth wears show that he might have been slave like vortigauns once... combine...)
here's what wikipedia says;

* "Comes... another...": Said when Gordon enters Xen for the first time.

* "You are man...he is not man...for you he waits...for you...": Said when Gordon enters the second part of "Interloper" at the alien camp. Perhaps refers to the G-Man?

* "The last...I am the last...": Said when Freeman enters the final part of "Interloper" near an altar with a red portal.

* "Win... you cannot win...": Said when Gordon enters Gonarch's lair.

* "Done...what have you done...": Said when Gordon enters the chapter "Interloper." This refers to the Gonarch and its defeat.

* "Die...you all die...you all die...": Probably spoken out of anger, may be related to above phrase.

* "Now die...now die...now...": Said during the battle with the Nihilanth.

* "Their slaves...we are their slaves...we are..." Probably a reference to the Combine.

* "The truth...you can never know...the truth..." Most likely referring to the G-Man.

* "Thieves...you all are thieves...you all are..." Refering to the Crystals that were stolen from Xen.

* "Deceive you... will deceive you" Probably describing the G-Man again.

* "Alone, not you... alone, not you... alone" Possibly a reference to G-Man?

* "FREEEEEMAAAAAANNN!!!!!": The Nihilanth screams out Freeman's name at the very beginning of the game's final battle, indicating that it knows Freeman by name.

quote

Until recently, many players speculated that the Combine may have possibly controlled Xen, based on the similarities to some practices and technologies used by the Nihilanth. However, Valve Software marketing director Doug Lombardi has stated that the Combine had, in fact, invaded a different homeworld from which Nihilanth's race was forced to escape. The defeated Nihilanth sought refuge in Xen, where the Combine could not (or would not) follow.

hmmm.. maybe the Cobine were in fact the Zan [See Half-Life Redemption]
