It's not deathmatch. It's a different variation of elimination. Plays the same except the rounds are longer. For the most part the only thing people hated about this variation was the wait period to respawn of you died early on in the round. The last popular server that had this was The Fish gg server that was a Christian gaming community and I believe that was back in 2014. Ggc also did this for a while but only as a private server for their tournaments.
