I got a good idea for an invasion map. Use the FX and set them on appear at certain times, so as the invasion progresses it gets lighter or darker
This is how FX are supposed to be done. http://www.forgehub.com/forum/reach-casual-maps/106603-flooded-mines.html
so if i've earned 750k credits, and im a lt colonel grade 3 right now, when they let us go to higher ranks, will i still be lt colonel grade 3 or will i go to commander grade 3 automaticly
