Well, I decided to make a Laura Croft character in Fallout 3 in preperation for the 2012 release of the Tomb Raider game.

This is what I thought:

Name: Lara Croft
Race: Caucasian/Asian
Hairstyle: No Nonsense (black)
Clothing: Merc. (That outfit with a simple brown shirt and baggy brown pants. Forgot the name. Is it Merc Grunt)
Weapon: 10mm Pistol

The SPECIAL thing, I don't know.

Advice?

S 5-6
P 7-8
E 5-6
C 3 (looks good, but not very friendly)
I 6-7
A 8-9
L 5 (Her luck is based on the player)

You'll have to use Intense training and/or Bobble Heads to get her stats to where they should be.

She uses assault weapons, grenades, and shotguns too.

Lockpick, science, and sneak are important for her to get into and out of places.

If you play on PC, there is a clothing mod that gives you Lara Croft's outfit.

Sounds like a very good character idea to me. Maybe you could take some clean Wasteland doctor fatigues instead of the Grunt outfit, because the bag would add some kind of realism.
