 Developer quotes
 Fallout 3
I used the W coordinate of the UVW to designate which verts were drawn when a body was dismembered. Limbs were created as contiguous mesh surfaces with internal 'meat caps' extruded internally at the line of separation. On limb removal 2 havok meshes were then generated; body with meatcap but no limb and limb with meatcap but no body. To simplify animation, dismemberment equalled death. Additionally, the W coordinates were used to designate which parts of the mesh were highlighted when limbs were targeted.”— Hugh Rileysrc
 Fallout: New Vegas
Even the "max" ranges of sight in F:NV are actually very short for firearms in the real world. Take one of the longest shots in the game: hitting Aurelius of Phoenix at Cottonwood Cove from the Sniper's Nest (where the Gobi Campaign Scout Rifle is found). We calculated it out and that's under 200 yards, I think. Apparent distances are skewed in the engine because the field of view is 70 degrees by default.”— J.E. Sawyer
