This contains logic within kismet for creating countdown timer. If you want to count up then reverse the math logic.

[Update 1/20/17] - Now includes logic to exit timer loop once countdown has reached zero (or whatever value you want)

rename to Park_P.upk and replace original Park_p.upk (TAKE BACKUP FIRST!) (wherever rl is installed)/rocketleague/TAGame/CookedPCConsole

1/20/17 - Added logic to exit timer once certain value is reached.
