To defeat Biker the player must first retrieve a golf club from the nearby golf bag and avoid all of his attacks. After missing two attacks Biker will throw his cleaver at Jacket. Should the player avoid the cleaver, Biker will run to his cleaver and attempt to retrieve it.
During this time Biker is exposed and can be attacked safely. Once the player has hit him twice, they must execute the Biker by smashing his head into mush with a golf club.
After main chaptersEdit
Biker is a playable character after beating Jacket's chapters. He starts each chapter with a meat cleaver that cannot be dropped, and three throwing knives for killing at a distance. Just like when Biker is confronted as a boss fight, if a throwing knife misses its target it will stick into whatever wall it hits and can be retrieved. The number of knives the player has on their person is saved at checkpoints.
Biker's path takes a divergent path than Jacket's. In his timeline, Biker wins the fight at Phonehom and his investigation reveals the true origin of the phone calls. His final chapter shows the confrontation between Biker and the two janitors in an underground lair full of phone equipment, animal masks, and 50 Blessings fliers.
Not much is known about Biker because he is not the main character. What can be gathered from Biker is that he is much more talkative and relatively saner than Jacket. Biker has spared the lives of some of his targets, for example the Chinese restaurant owner at the end of Safehouse. It's also optional to spare the employees of Phonehom and the two Janitors. That being said, he did join 50 Blessings "out of boredom" and wants out because it's "not exciting enough", suggesting a disregard for human life and a thrill-seeking attitude.
Biker's apartment is much better furnished than Jacket's sparse flat, which suggests that he is wealthier, or at least has some sense of taste. He seems to like music from the looks of his LP collection and turntables and the keytar on his bedroom floor. He has a computer in his bedroom and seems to have some hacking skills as seen in Prank Call and Resolution; this can also be seen as a stealth pun on his main weapon - the meat cleaver. He is also much more social than Jacket as there are signs of the aftermath of a party in the intro to Prank Call, including a girl in the bathroom and a drunk male sleeping on his sofa.
Like Jacket, Biker receives instructions by cryptic phone calls, which continue despite being shown to be sporadically followed. The message at the start of Fun & Games is the only one to name an address Biker visits, while mentioning that a previous task was not completed, and the messages in Prank Call and Resolution are disregarded. However the player still needs to listen to them to complete the intro, which may suggest dilligence in looking for clues.
When every puzzle piece is collected and properly arranged, it allows Biker to successfully enter a password on the janitors' computer during his final chapter, enabling him to convince the janitors to explain the truth about their intentions during their dialogue in the sewers.
- The fact that Biker meets Scar in an old restaurant, drives a motorcycle and seems to have more money than Jacket, could mean that he used to work delivering restaurant food, however this has not been confirmed.
