Need help creating timer

[BlackEnvyX]

Well, simply put. I need a game timer that says "Survive..." and it runs for 30 minutes. (The object of the map I'm making this for is to Survive for 30 minutes against a character called the lost one)

All that needs to be done is to create a timer that runs for 30 minutes. When the timer runs out, it makes all players except for player 12 (brown) win the game.

I have no clue how to work timers that count down (only ones that count up), that's the only problem lol. Can someone help?

Use a variable for the timer.
