The DLC was released on the 30th of July, 2019.
The Lightbearer DLC is what follows after Nick's death in the bathtub from Act I, where he resides at the Avalon Hotel for an upcoming concert.
Virgil Dainty, Nick's ex-agent, is there to help Nick remember what had happened to him and avenge his death. With Virgil's guidance, it aids Nick in his journey to redeem himself from his past mistakes.
Under assault by crazed fans, invading paparazzis, and angry exes who figuratively and literally, want a piece of Nick Lightbearer, who is a famous rocker (and a decadent, hedonistic hookup artist). Because he isn't a fighter, he has to resort to using the "Power of Rock'n'Roll" to fend off his crazy lovers and angry haters.
Nick will use his guitar to Facemelt and block his opponents attacks, vibe golden statues of himself to show him where to go, and find clues along the way that reveal what had been going on behind the scenes.
On top of that, Nick will use his (literal) golden hit records to throw at buttons out of reach, and attack his most threatening foes.
Nick is such a heavy user of drugs and alcohol that his body needs them to function. Therefore, everything that was bad for anyone else is good for Nick; binge-taking Joy, Scotch and Coffee will restore his Sanity with only the slightest chance of accidental side effects.
Nick wakes up in his hotel room during the Nick Lightbearer Fan Convention after Joy induced hangover covered in blood. He panics, searching for his reds and yellows, his ex-agent Virgil as a rat and his bathtub flooding the downstairs ballroom. Nick grabs his guitar, before sneaking out through the secret tunnel way to avoid the hotel staff. Escaping through the trash chute he goes to his "house" only to mistake it for the Nick Lightbearer Museum run by his ex-wife Petunia Penny.
After taking some of his secret bathroom stash he hallucinates himself shrunken to size, fighting a demonic Petunia. Defeating her he wakens to finds he fought a compliment machine. Virgil berates him for not wanting to remember, Nick makes the excuse that his amp is wet.
Once he gets into the music shop to get a new amp, the shop owner, Richard Bates, refuses to give him one as he deeply despises Nick for seducing his wife, Kitty Bates, as well as for simply being a musician. This forces Nick to return to the hotel.
In order to get his amp back, Nick dresses up as a bellboy and distracts the manager. This causes a short memory where Nick says he needs to go to the park, once in the park he finds the deceased Virgil in the arms of a golden Nick Lightbearer statue.
Facing the Music
Nick then wakes up back in his hotel room with another woman named Belinda who runs off into the bathroom to cry after Nick shows disinterest in her wishes, this causes Nick to go to the bar to "clear his head". Inside of the bar there are multiple people dressed as "Nick Lightbearer lookalikes", Nick overhears his former band member, Morrie Memento, crudely playing the song from his dreams, Nick suggest he'll steal the piano tuner back in exchange for hearing the song in it's entirety.
While on his way up to meet Dottie, he finds a bowl of Blackberry Joy that he mistakes for "party favours", as he consumes them it triggers a nasty episode of extreme, surreal and trippy hallucinations through distroted corridors, masks that whisper nonsense and is constantly being chased by flaming elevator doors with sharp teeth.
Nick wakes up from the nightmare on the top floor, where he finds out that Dottie in fact has a twin sister, Dodo, who desperately wants to "tame" Nick before giving him the piano tuner. Once Nick fights off Dodo and the other pesky fans, he retrieves the piano tuner and delivers it back to Morrie.
The song he plays being a piano version of "Into the Night" that is also performed at the end of the game.
After listening to Morrie's song, Nick is compelled to go to the rooftop, this is where he finds the dead body of Richard Bates, and the bellboy uniform he wore earlier in the DLC.
Not wanting to remember what had happened, he swallows five Joy pills all at once.
After another hallucination, he wakes up next to a deceased Kitty Bates, this makes him believe he is the one killing all of his fans and decides to hide away so he can't hurt anybody else.
The End Is Nigh
Nick decides to run away, but ends up falling through a loose opening in the ventilation system. He wakes up in the backstage of the bar where the Nick Lookalike Contest is taking place, Nick decides to go out and warn everyone about his misdeeds, but the contestants believe Nick is just another contestant trying too hard.
After fighting the contestants off, Nick heads into the kitchen and takes the dumbwaiter to the basement of the Hotel. In the basement, he finds that things are not quite as it seems.
As it turns out, the basement is only the beginning, for when Nick takes the elevator in the hotel, he descends further down.
Nick eventually ends up in Hell, with instruments, four body bags hanging and scuffling from the ceiling, and a pile of dead Nick Lookalikes placed behind a cage. The ground has turned into lava, and painful screams can be heard. At the end, there's a small graveyard and church that Nick enters.
Inside the church, Nick meets who's been behind the murders all along, Foggy Jack.
Foggy Jack had been the one who murdered all of Nick's fans, who did it so that Nick would write a song about him. Nick refuses to be friends with Jack.
Nick figures that the maze he's trapped in is the Hotel's maze, knowing there's a stage on the other side where he can defeat Foggy Jack for good. On his way, Jack taunts him that he'll kill all of Nick's fans, so that nobody will be left to remember him.
Once at the stage, Nick powers up the amps and begins the fight with Foggy Jack, who uses masks and smaller versions of himself to attack Nick.
When Foggy Jack is defeated, the DLC ends with a concert.
- The entire DLC is based on The Divine Comedy/Dante's Inferno, with Nick essentially being Dante traveling from Hell to reach Heaven.
- There's tons more religious references throughout the DLC, and some can even be found in the base game.
- The opening and ending cutscenes don't use the First-Person View. Instead, it shows a Third-Person View where Nick is actually seen.
- This only occurs during the Lightbearer DLC, as the base game and We All Fall Down DLC only shifts to Third-Person near the end of the scene.
- Interestingly, while the DLC displays Nick as being relentlessly followed and admired by crazy fans, in the main game it's implied that the fans have forgotten about him.
