You're wandering through the trash heap of Cyber City, and suddenly, a hyperactive puppet in a dumpster is screaming about "KROMER" and "BIG SHOTS." That’s Spamton G. Spamton. If you’ve played Deltarune Chapter 2, you know he’s the standout weirdo of the game. But there is a massive difference between the pathetic guy living in a literal dumpster and the winged, neon-drenched nightmare known as Spamton NEO.
Honestly, figuring out how to unlock Spamton NEO is a cryptic mess if you’re going in blind. Toby Fox loves hiding these things behind layers of "video game logic" that feels more like a fever dream. If you want to face the real secret boss of Chapter 2—not the pushover version you fight in the alleyway—you have to do a specific, multi-step scavenger hunt that involves back-alley deals and a very creepy basement.
Let's get one thing straight: this isn't the "Snowgrave" or Weird Route version of the fight. That's a whole other beast. This is the standard secret boss encounter for a normal playthrough. It’s hard. It’s rewarding. It has the best music in the game. Here is exactly how you make it happen.
Meeting the Salesman in the Dumpster
First, you have to actually beat Spamton in his initial encounter. You'll find him in the trash zone of Cyber City. It’s an unmissable story beat. Once you’ve survived his awkward sales pitch and the fight ends, he doesn’t just disappear. He sets up shop. You need to head to the far left of the trash area to find his "store."
Inside, the vibe is... uncomfortable. He’s selling junk. Most of it is useless, but you’re looking for one specific item: the KeyGen. It’s pricey. It costs a fluctuating amount of Kromer, but basically, just buy it. This is the literal key to the rest of the quest. If you don't have enough money, go grind some enemies in the city and come back. Spamton will wait. He’s got nowhere else to go.
Once you have the KeyGen, Spamton starts talking about a "special" place. He wants you to go to the Queen's Mansion. Specifically, he wants you to find a basement. This is where things get significantly more dangerous.
Navigating the Queen’s Mansion Basement
The Mansion is huge. It’s easy to get lost in the hallways filled with Swatches and Tasque Managers. To find the path to Spamton NEO, you need to reach the main hub of the mansion where the warp door is. From there, head to the right towards the long hallway that leads to the trash chute and the basement entrance.

You’ll know you’re in the right place when the music gets quiet and the atmosphere shifts. There’s a forcefield blocking a path downward. This is where that KeyGen comes into play. Use it. The forcefield drops, and you’re now in the basement. It’s dark. It’s eerie. It feels like you’re somewhere you shouldn't be.
Follow the path. You’ll eventually reach a room with a giant, mechanical body hanging from strings. This is the "Empty Disk." It looks familiar if you’ve played Undertale, specifically reminding some fans of Mettaton’s blueprints.
The Transfer of the Soul
You can't just fight the suit. It’s empty. It needs a "soul," or at least, whatever Spamton considers a soul. You have to take the Empty Disk back to Spamton at his shop in the trash zone.
Walk all the way back. Or use the warp door. Seriously, use the warp door.
When you give the disk to Spamton, he... does something. It’s not entirely clear what, but he "loads" himself onto the disk. It’s a bit tragic, really. He thinks this is his ticket to freedom, his way to "become a big shot" and escape the strings that bind every Darkner. He gives the disk back to you, now dubbed the LoadedDisk, and tells you to put it back into the suit in the basement.
The Final Step: Inserting the LoadedDisk
Go back to the basement. Navigate the puzzles again. Watch out for the lightning-fast obstacles. When you reach the empty suit again, interact with it.
Pro-tip: Save your game before you do this.
Once you insert the LoadedDisk, the suit comes to life. But it’s not a happy reunion. Spamton NEO realizes that even in this new, powerful form, he’s still hanging by strings. He’s still a puppet. And he’s going to take that frustration out on Kris, Susie, and Ralsei.
This is the point of no return. The fight begins immediately.
What to Expect in the Spamton NEO Fight
Spamton NEO is a massive spike in difficulty. If you’ve been breezing through Chapter 2, this will be your wake-up call. He uses a "Yellow Soul" mechanic, similar to the Mettaton EX fight in Undertale. You’ll be shooting bullets to destroy his attacks rather than just dodging them.
- The Phone Hands: He’ll turn his hands into phones and blast you with sound waves.
- The Face Attack: His face breaks apart and shoots "shrapnel" at you.
- The Pipis: He’ll launch blue eggs (Pipis) that explode into more Spamtons. These are annoying. Destroy them quickly.
If you’re going for a peaceful "ACT" victory, you need to use the "Snap" command. Kris will try to snip the strings. It takes a long time. You’ll need Susie and Ralsei to use their turns to heal or provide defense while Kris focuses on the strings. If you’re going for a violent victory... well, just hit him really hard. But be warned, the ending of the fight changes slightly based on your methods.
Why Bother With This Secret Boss?
You might wonder why you’d go through all this trouble. Is it just for the lore? Not really. The rewards are some of the best in the game.
If you defeat him by "Snapping" all his strings, you get the Dealmaker. This is an incredible armor piece that boosts your defense and significantly increases the amount of money (Kromer) you get from fights. It’s basically the best defensive item for Kris at this point in the story.
If you defeat him through violence, you get the PuppetScarf. This is a weapon for Ralsei. It gives him a massive attack boost, which is great if you’re playing a more aggressive style, though it does lower his healing effectiveness slightly.
Beyond the loot, the Spamton NEO fight is widely considered the emotional and mechanical peak of Deltarune Chapter 2. It explores themes of freedom, puppetry, and the desire to be "real" in a way that the main story only hints at.
Practical Next Steps for Your Run
Don't rush in. Before you head to the basement for the final time, make sure your inventory is packed. Stop by the café in the Queen's Mansion and buy some CD Bagels or Choco Diamonds. If you still have the TopChef cake or the SpinCake, save them for this fight.
Also, check your equipment. Make sure Susie has the best axe available and Ralsei is kitted out with the DaintyScarf or something similar to keep his Magic stat high for healing. You’re going to be using "Ralsei Prayer" a lot.
Once the fight is over, don't forget to talk to the Shadow Shopkeeper (Seam) back at the Castle Town. They will have special dialogue about the "Shadow Crystal" you get from Spamton. This is part of a larger meta-quest that spans across all chapters of Deltarune, and you'll want that crystal for whatever Toby Fox has planned for Chapter 3 and beyond.
The Spamton NEO encounter is more than just a boss fight; it's the culmination of the weirdest subplot in the game. It’s creepy, it’s fast-paced, and it’s exactly what makes this series so memorable. Good luck. You’re going to need it when those "Big Shot" lyrics start kicking in.
