Pushing Ghost through broken blast doors in 2 Betrayals [fast mode]
Make sure you have your banshee with you when approaching the blast doors that will blow up and break down. Some think that it's not possible but it is with help of banshee. After putting down several floodies, go get the ghost that's parked at end of inclined tunnel and back the rear portion of ghost between broken blast door and jump through the opening. Then get in your banshee and use it to "push" ghost through the broken door and voila! You have your fast mode of transportation from that point.
