I'm terrible at scripting but try this:
;Artificial Intelligence Script by THE GOZ
;Header
desc = enter to timer then end game
;Triggers
state=0:plrdistwithin=1000:fpgcrawtextsize=16,fpgcrawtextb=255,fpgcrawtextg=255,fpgcrawtextr=255,fpgcrawtext=2 minutes untill evacuation helicopter:state=1
state=1:plrdistwithin=1000,etimerstart:state=2
state=2:etimergreater=[5000],[COMMAND FOR ENDING LEVEL HERE]
;End of Script
Remove [] and enter your own value
I can't check this for you because my fpsc is being weird but I hope this helped.
I also need to remove the "COMMAND FOR ENDING LEVEL HERE" as I need to find out what it is but again I can't because of my fpsc. Find this out yourself by looking at the script for the win zone and look at the relevant commands.
I'll edit this as soon as I find out.
