Five players stopping on the spot to carry out their similar death animation in the midst of a mushroom cloud is neither move style nor realism.
In UT3 you could feign death and turn yourself into a rag doll at any time you liked (in mid air if you wanted), you could tumble down the stairs and stand up right on the spot where your body came to halt, other players could even interact with it by shooting at it.
So in that way, ragdolls + interaction is perfectly possible UT3 has already demonstrated it. If the whole thing is about lying on your back, that wouldn’t be a problem either as SD already solved this by letting players who lie prone make an amateur dramatic roll on their back when they die.
