In the Alternate Damage system for ORE, height is used to represent the severity of the wound, rather than the hit location. In this system, location is not tracked (unless the player chooses to sacrifice a limb to the damage, see below). There would be four wound severities: Superficial, Serious, Critical, and Mortal. The heights and number of wound boxes are as follows:

Mortal (10): 4 Wound Boxes
Critical (8-9): 4 Wound Boxes
Serious (5-7): 5 or 6 Wound Boxes
Superficial (1-4): 5 or 6 Wound Boxes

(Note: I'm not sure if 6 wound boxes is too much for Serious and Superficial)

Characters suffer the following (cumulative) penalties when they have all damage boxes in the appropriate category filled with Killing Damage.

Mortal: Dead
Critical: -1d to all actions
Serious: -1d to concentration actions
Superficial: -1d to physical actions

Damage rolls up, so a character that takes 5 killing and 5 Shock superficially would fill in five killing, use two points of shock to fill the last box in Superficial, and then put three points of Shock up into Serious. This character would suffer a -1d penalty to all physical actions.

As a further option, groups may choose to switch Weapon Damage to a flat scale with this (remove the width bonus to all weapons). This depends on how deadly you want things to be. If you remove W from damage, default all W's in the listed Weapon Damages to 2. This is really up to style of game you want. Removing the width from damage "standardizes" the system, leaving width solely an aspect of speed.

Players can "sacrifice" a limb rather than taking damage from an attack. Sacrificed limbs are useless. Useless limbs have the same penalties as you'd normally associated with them (as if the limb was filled with Shock damage). Limbs can be sacrificed twice each, the second time the limb is completely destroyed/removed (i.e. will never heal or function again;treat as if filled entirely with Killing damage). Limbs sacrificed once will heal over time and regain functionality.
