While it’s not technically a Half Life game (it’s in the Half Life universe, so I think it counts!) are the turrets from Portal.
I don’t blame you…
Or, perhaps GLaDOS’ curiosity sphere.
Oooh, what’s in he-ere?
Favourite?
Barnacle…
That thing eats everything:retard:…
I always lure scienctists into the barnacles tentecle… 
Just so fun to watch them get eaten…
Oh and i also love my squiddy:3… I feed him extra (dont know what) every day just so he can blow **** up! :freeman:
I like headcrabs.
(lolgeddit)
HEAD-FRIKIN HUMPERS, BIATCH!
The female assassin, technically since it is a creature in the Half-Life universe. :jizz:
Strider and Hunter. When I first saw Strider in HL2 I was like “wow”. and the Hunter because it is really challenging and fun to kill.
HL Universe - I would also include GlaDOS of course - FOR SCIENCE… YOU MONSTER!
I don’t think supercomputers are creatures
oh yes they are :hmph:
crea·ture
- Something created.
That really is a creature from the half life games hes from Half life 2 beta Ever readed combinewiki instead Of keep on reading black mesa?
Yeaaah, those turrets really made me laugh 
But i think my favorite is Lamarr… I mean, it’s a headcrab, the perfect pet, lol.
I like the houndeyes, like in freemans mind in that outer blast pit area they start doing flips n’ shit after I kill 'em, good 'ol PS2 memories.
In Scandinavia Norway: we don’t have a favorite creature, we do them!
Edit: I just wanted to post that…
A favorite creature to do?
Also I like the Overwatch soldiers, very satisfying to attack with a shotgun
when i post something i don’t do it because i want to post it.
I liked the baby head crabs they were cute 
Freemans Mind is a game? And PS2 HL had the physics for houndeye flips?
M favorit creature in Half-Life would be the Bullsquid and the houndeye and in Half-Life 2 it would be strider and antlion. :freeman:
The garden gnome, who else? :3
My favourite creature is always the last one I just pumped full of lead!
