well u can call it hybrid or matilda. <img src="/ubbthreads/images/graemlins/tongue.gif" alt="" />
for fallout tactics, & i think fallout in general as well, action points (AP) is used as a measurement of how much u can do in a preset time. the more APs u have, the more that u can do in a preset time (let's say 1 second).
now let's say punching requires 2APs. wielding a knuckleduster also means 2APs. however wielding a sword which is relatively big(depends on size & strength) for your character will mean using it will cost u 4APs. if u want precision in your attack, it will cost u 5APs. so trade offs between fast & weak attacks versus slow but powerful attack becomes evident.
normally AP generates about say 1 point per second. now if u choose a perk (fallout version of feat) that increases the speed of your AP generation, your character becomes 'faster'.
a character can have a certain number of AP. this can be increased by boosting agility.
of course it's actually time-based, if u look at it in certain point of view.
