I am looking for a plugin which does some special, but I really can't find any...
Random Respawn Round is the plugin name and it's a simple idea but maybe hard to code
Before every round starts, there should be odds 1/50 or 10 /100 if the round should be a Respawn Round. If it's a Respawn Round, the round should just countdown from 3 minutes, where people respawn all the time. When 3 minutes are done, a new round should start with same odds.
If not respawn round then it's just a normal round.
