Even in 2026, the secret boss of Deltarune Chapter 2 remains a rite of passage for any self-respecting indie RPG fan. Spamton NEO isn't just a boss; he's a chaotic, glitchy, and downright brutal test of patience and skill. Players who stumble into his lair without proper preparation will quickly find themselves singing the blues. But fear not, because this guide will walk you through every step—from finding those pesky blue checkmarks to delivering the final blow (or cutting the right wires). So grab a Butler Juice, keep your eyes peeled, and let's dive into the weird world of Deltarune's most infamous secret boss.

Step 1: The Hacker's Wild Goose Chase

First things first: players need to find Hacker in the Cyber Field. From the first main area, take the crossroad east and then immediately north. Hacker will ask for three blue checkmarks. This is no walk in the park, but it's doable.

• Checkmark #1: Leave Hacker's area, go east and then south. Players will end up in a zone with roaming Tasques. Take the lower east exit to find a chest containing a GlowWrist and the first checkmark.

• Checkmark #2: Head to the teacup rides area. The center ride will take players to the blue checkmark. Kris specifically must make contact with the arrows to progress. At the top is a chest with the second checkmark.

• Checkmark #3: Take the left teacup ride to the top, again using Kris to hit all the arrows. At the top, a typing puzzle awaits. Players need to type 'GIASFELFEBREHBER.' Get it right, and the last blue checkmark is theirs.

Once all three are collected, return to Hacker. He'll reward players with fireworks, but that's not all—he'll show up later to lend a hand. Talk about a good turn.

Step 2: The Queen's Mansion and the Secret Passage

After completing Hacker's side quest, he appears in the Queen's Mansion. After encountering the Tasque Manager, the next room has stairs and a road. Players must use stop buttons to freeze traffic for short bursts to avoid getting hit. By taking the east exit, they'll find a room with statues of the queen and Hacker pacing around. He'll spill the beans about a secret passage.

To find it, watch him walk around the room and wait for his body shape to change from a normal mouse cursor to a click mouse cursor. Where that change occurs is where the button to open the secret passage is hidden. The tension keeps building bigger and bigger.

Step 3: Spamton's Shop and the Key-Gen

The passage leads to a basement, but it's locked. Players need the Key-Gen, purchased from a secret shop run by Spamton, an earlier boss. To find the shop, warp from the mansion to the Trash Zone, head left into the following map, and go north through the hole in the wall. Only Kris can enter this shop. The Key-Gen may cost an arm and a leg at first, but its price is ever-changing. Players should keep trying to buy it until they can afford it. After buying the Key-Gen, the shopkeeper asks Kris to fetch a disc from the basement and bring it back. Let the fetch-quest begin!

Step 4: The Basement, the Disk, and the Robot

Back in the basement, take the west path (the east path is blocked) and be extremely careful—traps and hazards will damage Kris. The furthest left room may seem empty at first, but a teacup ride appears that leads to a switch. Flipping it turns off the forcefield blocking the east path. This new path takes players to a room with train tracks. Go into the east room from here to find a robot holding the disk.

When players return the disc, Spamton warns that this will make his shop forevermore inaccessible. So buy anything you want beforehand. Spamton then asks players to return the disc to the robot they found it in. Returning the disc to the robot triggers the secret boss encounter. This is a good time to ensure health and equipment are up to snuff and save the game.

Step 5: The Spamton NEO Fight – Preparation and Mechanics

As stated above, the most important step is to go in prepared. Butler Juice, which heals 100HP in battle, can be bought in the Queen's Mansion and could be a game-saving item. If it's within the player's budget, armor bought from the same café is also recommended. This boss hits hard—like a truck.

The main mechanic is using the soul to shoot bullets at any of the blue objects shot out by the boss. Failing this results in more bullets covering the screen. The fight can be completed in one of two ways: attacking the boss until his health runs out, or using the Act command to snap all of his wires. During certain attacks, the boss exposes weaknesses like hearts, eyes, nose, and mouth. Players can break these parts to stop the bullets from being fired out of them.

Step 6: Rewards and the Shadow Crystal Mystery

Depending on how players choose to fight this boss, they'll receive different rewards. By attacking, Deltarune players receive a Puppet Scarf, a weapon that can be equipped to Ralsei. By cutting the wires, players receive a Dealmaker—armor that increases defense and money earned in battle. No matter the playstyle, players also get a Shadow Crystal. Based on in-game text, more of these crystals will show up in chapters 3-5, and their mystery will be further unraveled.

So there you have it. Even in 2026, Spamton NEO remains a highlight of Deltarune Chapter 2. It's a tough nut to crack, but with the right preparation and a bit of patience, players can come out on top. Just remember: don't throw in the towel, and always keep a Butler Juice handy. Break a leg!
