I can't emphasize this enough: know your strengths, but more importantly, know your weaknesses. And make sure everyone else does too. As a Game Master, you can't keep track of every character's injuries. You only have to keep track of the GM characters, not the other players. That's your friends' job.

The character sheet is so vague. Stunned, wounded, twice wounded, incapacitated, and mortally wounded. That doesn't say much, does it? You have to know where the character is injured to fully account for anything else that happens to him/her. And you or one of the players might forget that a character is hurt and forget to compensate for it in future rolls. So write it down. Or for better clarification, draw a chart and mark where the injury is. You don't need to be an artist as long as you know what it means when you look at it later.

As far as letting chance determine where a character gets hurt, you should use a hit chart. To use the one I've supplied, follow these simple instructions. I'll give an example to follow. A Stormtrooper is shooting down a hallway at Jedi Jake. Jedi Jake tries to dodge but is hit. Where?...

1) The GM rolls one six-sided die. This determines which general part of the body gets hit. Example: The roll is a 3. Jedi Jake is hit somewhere on the left arm.

2) The GM again rolls one six-sided die. This determines where on that general part of the body the character is hit. Example: The roll is a 1. Jedi Jake is shot in the left shoulder. If the roll is a 6, go on to step 3. Otherwise, skip step 3. Go directly to step 4. Do not pass Go. Do not collect $200.

3) If necessary. The GM once more rolls one six-sided die. This would determine which finger or toe was shot.

4) Roll damage as normal.

5) Here's where it could get hairy. This is only for those of you who want to play pretty technically and let the dice do it all. You could just say "okay you drop your gun" or "okay, you fall down" or "roll your dexterity". If the character is carrying something in the arm or hand that was hit, he/she may drop it due to the shock, pain, or force to the arm or hand. Example: Pilot Pet is holding a blaster. He was shot in the elbow (this is only for elbows down to fingertips). Pilot Pete's player rolls one six-sided die. If the roll is 1-3, Pilot Pete drops the blaster. If the roll is 4-6, Pilot Pete manages to hold onto the blaster. The same goes for the legs. Instead of elbows down, it's all over. If you get shot in the foot or shin, you're likely to hop around. If you get shot in the groin or thigh, you're likely to drop flat on the ground and moan a lot. In the knee, you'll probably try to hop hunched over, stumble, and maybe fall. Roll for this also. Maybe dexterity too. Play around with this one. And for your own GM-ing sanity, man, write it down!!!

Reminder: The number of sides on the die may vary by the number of limbs the character has. The example given is for a creature with a head, torso, two arms, and two legs.
