When you enter Fortune Park, go to the red SUV--which costs $2 million to unlock by buying the keys. Get in the SUV and drive to the entrance of the underground area, squeezing the SUV into the underground area. When you get to the entrance for the loading bay, notice that it is blocked off by a line of large boxes. It is possible to drive over these boxes and squeeze the SUV under the security gate, which will trigger the cinematic for the Boss fight against Sgt. Dwight. After the cinematic, you will be on foot again. However, if you look at where you entered, the SUV is stuck halfway in the room. Get in the SUV and squeeze it in the rest of the way. Use the SUV to kill Sgt. Dwight.
