I would be oddessa cubbage.
I get tah call radios!
And hand RPG’s to rouge physicists!
In all seriousness, I would be an advisor.
So I could…ahem…“feed” off of alyx with my…“proboscis”
[Awkward pause.]
i would be a nihilith…
I would be a Aperture Science Party Escort (in the half life universe bitches!)
I would be a FROZEN CHAMELEON
Frozen Chameleon? Really?
and a cockoroach would do just fine for me:retard:
A domesticated houndeye that gets petted by the rebels and kicks combine ass.
hehe! Frozen Chameleon is my BMS ID… -v-’
in fact that i would rather be a vortigaunt… it can evolve so quick!
Well, Striders DO shoot lasers out of their dingdong…
Snark
Gargantua 
I Would like to be a a Vortigaunt, the Handfire Lighting is Pretty Fucking awesome.
I would be a poison zombie, just to annoy the shit out of gordon if he ever comes along.
I’d be a headcrab. Just think about it. You take over someone’s BODY! when it get shot down, you can just jump off and find a new body.
unless you get shot in the head with literally any weapon in the game
I’d be a strider, who wouldn’t want to fire lasers from their yard long penis?
I think being a hunter would be sweet, tough question to answer.
If anyone says they want to be a zombie, that’s wrong, because you’d be going under all the torture and pain from the headcrab. You want to be the headcrab so that you can control the zombie without feeling its pain.
I’d be a Metro Cop. You know, telling people to pick up cans :awesome:
Easilly the creature from Op4 who eats and spits out the green balls, all while being coddled by adrian^_^
Tentacle.
“Hey, baby. Check out how long I am…”
