Hey :)

I'm trying to make an ICBML (inter-continental ballistic missile launcher) which is basically a nuke on wheels. I pretty much got it done except for the reload rate. I only want it to fire once, or take about 25 mins to reload. I tried setting a very high value on reload rate and that caused the game to crash. I also tried -1 and -2, that just made them shoot unlimited nukes as fast as they could. Anybody got any ideas?
