theres one reason why this won't be made:
blockland runs on the torque engine, which isn't as advanced as other engines that games like call of duty or halo use. yeah there's brick physics/player physics/other physics, but if you're asking for people to die in the style you are requesting, which i assume is like a ragdoll, it can't be done because torque cant do it.
tl;dr: it cant be done. (correct me if i'm wrong)
