The Captain 32 lesson added a tablet option for killing and others to use. If you found the tablet you would find distorted videos that give hints on ways to get out. There is even a small chance it is a video of where the exit is. Major 33 lesson added a swimming option. Though it isn't the best choice, there will be openings to the water to try and swim away in to escape. However the killer can still swim after you and claim your life depending on the distance you have put in between you and the area of killing.
Colonel 34 added a diving spot. Finding a sewer lid, one can try and go diving in it and find an exit grate. However there is a chance to drown inside, so the person must exit out to get air but this gives the killer a chance to kill the person.
