You know, I know helluva lot of trigger combinations ranging from aircraft bombing the crap out of a place, tanks blowing up walls, launching missiles, breaking stuf, exploding machines, and so on and so forth. Why don'y you send me the SP map outlines now? So I can help with those triggers 'n' movers, decorating and stuff. Oh, and a very important tip on SP, movers and triggers actually IMMERSE the players into the action making them believe their interactive world is real cool. Try making a canyon. When you arrive into the canyon, a plain is triggered to cross by and launch warheads all over the place. That's a good immersing event.
