Round timer and Stay dead ?

Hey guys, i wondered if there would be anyway to make the player stay dead when they are killed, untill the end of the round, also, would there be any info on the wiki allowing me to add a round based system on my gamemode? (Maybe how to add a timer for it on my hud, and team score on each side of it)

I also wondered, would there be a way to make ragdoll of a player do the idle anim when killed, and then disapear? (Or just disapear)

I looked a bit for those, but haven’t found anything to help me =/

Thanks ^^
