Movement: Your base speed (the order in which you act in combat) is (DX+HT)/4, and your move is the greatest integer less than ((DX+HT)/4 X [Encumbrance] Modifier), counting your body and whatever you're carrying for Encumbrance. It's how fast you move in yards per second. If you have the Running skill, it replaces DX in the calculation of your Move. If you have the Sprint Talent, it adds to your move *before* modification for [Encumbrance]. That is, Move becomes floor(((HT+DX)/4+Sprint) X Enc Mod) Strain and Fatigue: By default, you have fatigue equal to your HT. Some things can cause you to take fatigue directly, but often you get if from strain. If you take a point of strain, roll vs HT+5-(points of strain) to see if you take a point of fatigue.

Guns (Light Auto), Guns (Pistol), Guns (Rifle), etc.DX-3Physical/EasyAll Guns skills require a specialization, but default to other specializations at -2 (-3? not sure right now), and to Beam Weapons skills at -3 (-4? not sure right now). Also, Guns (and Beam Weapons) get a +1 for IQ 10 or higher, and an additional +1 for IQ 12 or higher.
