When you play "Film Order" & it stops in front of Ripley just hit shoot button again & that just triggers the mission. It's mostly for when you play your own selection, the missions you select through are displayed in that box that's in the upper left corner of the game, when you hit the flipper button, you'll see that it changes to different names & that's the different missions, there's 6 or 7 I think. I mainly play "Film Order" just to keep things simple & keep the game flowing more. I did figure out how to get the APC thing going, it's part of mission 1 in Film Order. When you start the mission, you have to shoot for the Hicks ramp, Hudson ramp, Vasquez ramp or the Burke ramp to look for Newt. Once you find her in one of those ramps, then you shoot for the atmosphere processor that closest to your RIGHT flipper & that triggers the APC driving. I've still yet to survive the 45 seconds of Aliens coming at me so I don't know what happens after that part yet haha
