anyone know if you can time a visual effect with an invasion phase? if so you could do a power cut event timed with shield doors dropping and the lights going out (purple lens), which would be sweet marine 1 - "they cut the power man, how could they cut the power, their animals!" marine 2 - "actually, they're quite clever. They've got lazers and everything...."
Actually I implemented something like that in my map. I used effects to make a functioning day/night cycle. edit: here's a url link since text links are hard to see now - http://www.forgehub.com/forum/halo-reach-forge-discussion/106758-atarac-valley.html
