Character Attributes

MP characters are composed of seven attributes in the range 0-20 (4d6-4):

• Strength
• Constitution
• Dexterity
• Accuracy
• Charisma
• Psionics
• Luck

Of these, the most important for our purposes are Strength and Constitution, as these are used to calculate Structure Points (Sp) and Blood Points (Bp).

Sp = Bp = STR x CON + 100

This yields a range of 100 - 500, with 250 as the mean, and approximates the character's size or body mass.  Structure Points represent the amount of physical damage a character can withstand, while Blood Points represent the amount of blood in the character's body.  (Can't forget to bleed, now can we?)

Body Percentages

The total Structure Points are divided over the entire body to represent loss of function in each part of the body as it takes damage.  This is done by dividing Sp by the approximate mass percentage of that part of the body, rounding upward to the nearest whole number.

Blood Type

MP also requires each character to know their blood type.

Ammunition, Armor, Penetration, and E-factor

From the Morrow Project rules:

"A projectile carries energy with it to the target and in this manner causes damage.  This energy takes the form of the speed in which the projectile strikes the target.  It was to account for this energy that the E-factor was developed."

"The term E-factor comes from the Efficiency of a projectile.  It accounts for the amount of armor a projectile can penetrate as well as the damage it does.  The E-factor is found by multiplying the projectile's diameter, in thousandths of an inch, times the muzzle velocity of the projectile, in feet per second, divided by 50."

(D x V) ÷ 50 = E
