What it does
Puts the server back into warmup: players respawn, scores do not count, and the warmup timer from mp_warmuptime runs. Handy when players drop and you want to wait for them without the score counting. End it with mp_warmup_end.

Run it on your server
On a SLASHPLAY server, type it in the Console tab of the server page; the reply shows right under it. A value set there lasts until the server restarts. To keep it, add the line to game/csgo/cfg/server.cfg. New to this? Start a CS2 server first.
