No Mutants Allowed

Give them independent eyes like the chameleons they're based off of.

And when they first see you they stop moving and just stare while looking at you with both eyes locked on until you move far away enough to give chase or break eye contact with them.

It's not a horror game necessarily but I feel there is not enough tech horror, and walking the wastes at night should be eerie. Usually it isn't.

Well they were more based off terrasques, the origin of the deathclaw was supposed to be a Jackson Chameleon but I remember it being stated that they weren't supposed to only be that. Just the basis for the being. Also their original design was supposed to be mammalian.

Also, go play Fallout 1 and 2 dammit

You probably have never done a Iron Man run and had a Mother Deathclaw barreling down towards you.

The F3 design was scarier imo.

Ah yes the 3D drawn deathclaw is surprisingly scarier than a clay model used for a cRPG. Cmon, yeah it's scarier visually, its got more detail to it.

I remember talking to that idiot in FO3 who is obsessed with Nuka-Cola and turning around to leave her shack when a deathclaw just walked through the door. It raised an eyebrow, still though, Mother Deathclaw barrel roll.

I was thinking more in comparison to 4 since they went for a "cool" dragon look and the animation is like sloppy breakdance sometimes. Doesn't do it for me. Looks "cool" sure, but I think it's the weakest showing from the series. OG ones actually seem fine now that I look at them.
It's the direction 4 went in that I don't like.

That's fair. 4 did quite a lot wrong.

They might be less creepy due to all the porn you peruse with deathclaws and other beasties.

Ah yea, very sexy. Death by impalement. *masterbates furiously*
