@ranma50387 Body parts are for jointing to the ragdoll if he loses a body part(s) and also for making mutants. The blood bag has to be linked (O default) to the ragdoll and will slowly drain it's health while healing the body part(s) it's linked to.
Really needs a story mode. Similar to the CoD Story. Simply you are with other soldiers and with certain guns. Also there are the same maps as multiplayer but on the start everything is not destroyed (At the evac map at the big base there aren't rocks).
0rava,I have an another technology thing. It's the plasma shield! Works similary to the repelfield,except DISINTEGRATES everything that touches the ray.
@egnoder The drones don't trigger what they are linked to. They simply wander around untill something triggerable gets in range. They float to it and untrigger/trigger it.
