Dr. Hax!!!
You can shoot f*cking pc’s out of your finger ^^
I would be a SeaGull from HL2 Damn i could peck the shit out of the combine
The Nihilanth! That would be amazing because i would be the only lifefrom after the gman maybe, who knows the truth! Also you spawn Vortigaunt’s, shot Beams and teleports.
Of cause i would be in a prision of a cave in XEN, but i see it positive: As long as no Gordon Freeman comes along, im immortal because of the yellow crystals.
Also i have telekinesis to speak with humans and i could fly!
Ok, Nihilanth is ugly as hell, but who cares

I’d either be a Hunter or a Vort. (with god mode on, 'course)
Adviser
I would be a citizen!
Oh wait…
I would be a human. I have had the most experience as one and would therefor be most efficient as one. :freeman:
Hmm. I would have to say I’d go with DOG. He probably has seen some fantastic things on his adventures with Alyx. In all seriousness though, I would say I would like to be a roller mine. Tumbling in the breeze.
Whoever the G-Man’s bosses are, I mean if he’s the scary shit, what are HIS employers like?
Well scientists are basically creatures, so a scientist!
I’d be a headcrab!
These things are so cute :3
Like the EMPEROR ING in Metroid Prime 2: Echoes? it could make paradoxically physics-warping light beams with its literally 20ft long “tentacles”.
I’d be Gordon, a citizen, or Gman probably. I was thinking a scientist would be fuckin’ funny too…
