In this chapter you'll be out for revenge against Kramer for trying to kill you and Lauren (and perhaps succeeding against Lauren). Using Lauren's car, since yours is at the bottom of a large body of water, you'll crash the mansion and go on a killing spree.
Storm the mansion
Press to rev your engine, then put the car in gear and press again when you're ready to go. You'll crash through the wall of the game room, slamming the pool table into a guard inside. Press to exit the vehicle, then kick down the the doors with a downward tug on the controller after shooting the half-crashed guard. From here on out, you'll face a long series of shooters in a quicktime sequence as you make your way through the house to Kramer's upstairs room. The come from all around and the pacing is staggered, so don't get too comfortable. If you can make it through without taking too much damage, you'll be able to bust down Kramer's door. If you get too shot up, you'll retreat, running out of the house and down the driveway.
If you made it through the house, you'll rush over and grab Kramer after kicking in his door. Throw him around and slap him around for a bit while he blubbers. He tries stonewalling you, but once you start choking the life from him, he'll spill his guts to you. It turns out his son Gordi is just a wannabe Origami Killer, and the one kid he killed was basically an accident. As leave to go, Kramer makes the mistake of saying no one will miss the little boy. When you come back you can ask him some more questions about John Sheppard and why he puts flowers on the boy's grave. If Lauren died in the car, he'll call her a whore and try to hire you, which only antagonizes you further. When you go to leave, Kramer will have a heart attack and ask you to get the pills in his desk drawer for him. Either grab the pills for him or walk out the door and choose to leave when prompted.
Depending on how you've played up to this point, you could miss four chapters after this one and end up going straight to Hold My Hand. If Madison is dead you'll skip Ann Sheppard, if Ethan is locked up you'll skip the Rat trial, if Jayden is dead you'll skip Solving the Puzzle, and if Lauren is dead you'll skip Goodbye Lauren.
