That's the big problem...people think shotgun slugs carry bodies...in fact it'd just tear right through the person, and the person would just fall limp...he wouldn't go flying.
They wouldn't even go through. They'd rather stay inside your body and possibly kill you, if you manage to survive the bleeding.
In my opinion it wouldn't fit in Brink, cause theres already the incap animation, which is shown in the "Ready and Able" video where an enemy is incapped while falling he remains in the incapped animation.
Also, that Overgrowth video was pretty interesting, it was the closest thing to "realistic" ragdoll.
The
Overgrowth-Video pretty much showed how well Ragdolls could work in BRINK, by fluently blending the ragdoll over into the incapp-animation.
