Like Attrition, but players are rewarded for attacking larger opponents.
Enemy Damage Inflicted...+(damage done * tonnage ratio * 2)
Enemy Component Kills...+50
Enemy Kills by Tonnage...+(400 * tonnage ratio)
Note: For the score calculations the tonnage ratio is always at least 1. So if you kill a smaller 'Mech, you will score 400. And for every point of damage you would score 2.
Friendly Damage Inflicted...-1
Friendly Component Kill...-50
Friendly Kills...-500
Suicides...-1500
Note that the score losses are generally only for self-inflicted damage. Being killed by another player only adds to their score, it doesn't hurt yours.
