In the ever-expanding universe of Deltarune, Chapter 2 remains a free, delightful, and slightly unhinged gift. Even in 2026, when every pixel has been datamined and every secret has a wiki page longer than a terms-of-service agreement, the chapter's hidden boss still makes players weep into their keyboards. That boss is Spamton NEO, a glitchy puppet of capitalism and bad decisions. Reaching him is like trying to assemble IKEA furniture while a raccoon steals the instructions: doable, but only with patience and a tolerance for chaos. The journey requires a sidequest, a secret shop, a robot, and a willingness to ignore Susie and Ralsei for a while. Below is the full route, spoilers and all.

Step 1: The Hacker's Blue Checkmark Scavenger Hunt

In Cyber Field, players should start at the crossroad near the entrance to Deltarune city and go east. Instead of entering the next bullet-dodging area, they go north. There, a mouse-cursor fellow called the Hacker asks for three blue checkmarks. He promises help later. He is as subtle as a fire alarm in a library, but his quest is essential.

The first blue checkmark is found by leaving the Hacker, going east through the first bullet-dodging section, then going south instead of through the second bullet section. This leads to an area with multiple Tasques roaming around and ready for battle. Taking the lower east exit reveals a chest containing a GlowWrist and the first blue checkmark.

The second checkmark is in the area with the three teacup rides. Of the three, the center one leads to the checkmark. Players must turn the ride so that Kris makes contact with the arrows as the group ascends. Susie or Ralsei touching the arrows will not count, and missing any arrow sends the ride back to the bottom. At the top is a chest containing the second checkmark.

The last blue checkmark is found by going up the left teacup ride and hitting all arrows with Kris, just like the middle ride. Instead of a chest, this leads to a typing puzzle where players must type GIASFELFEBREHBER. The phrase looks like a cat walked across a keyboard, but it is easy if players take their time. The next letter is usually next to the key they are currently standing on, and stepping off the keyboard is safe. Typing the phrase grants the final blue checkmark.

After getting all three, players return to the Hacker. The apparent reward is fireworks. That is like getting a single french fry when ordering a burger, but the Hacker returns later in the chapter.

Step 2: The Hacker in Queen's Mansion

If players complete the Hacker's sidequest, he appears in two different places inside the Queen's Mansion. After encountering the Tasque Manager, the next room has stairs and a roadway with oncoming traffic. The stairs lead to story progression and can be ignored for now. Players must use the various stop buttons to freeze traffic for short bursts and avoid getting hit.

After getting through all the cars, players can reach the east exit. Reaching this exit stops the room's traffic for good, so the stop-button puzzle does not need to be repeated from that point onward. The room to the east is filled with statues of the Queen, tables, signs, and candlesticks. If the sidequest was completed, the Hacker is pacing around the room. Talking to him reveals that he knows of a secret passage somewhere within the room.

To find it, players need to watch him pace and look for his body shape to change from a normal mouse cursor to a click mouse cursor. Where he changes is where the button opening the hidden basement passage is. Press it to open both the passage and a shortcut back to the Mansion's main hub area.

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

While the entrance to the basement is available now, the basement itself is still locked. To get access, players need an item known as the Key-Gen. This can be purchased from a secret shop run by the mini-boss from earlier in the chapter named Spamton.

To find Spamton's shop, players go through the warp door in the Mansion to the Trash Zone. Heading left from the door into the following map and going north through the hole in the wall brings players to a shop that only Kris can enter. This is Spamton's shop, a place filled with glitching text and items. One of the items sold is the Key-Gen. While it may be expensive, its price is constantly changing, so players should keep attempting to buy it until it changes to a price they can actually afford.

After getting the Key-Gen, talking to Spamton has the shopkeeper ask Kris to get a disk from deep inside the basement and bring it back to him. With the newly bought item at hand, players can move on to the next step.

Step 4: Kris's Solo Basement Adventure

When going to the basement, Kris will not let Susie or Ralsei follow. A forcefield blocks the eastern path, so players need to take the west path. There are hazards that can take a bite out of Kris's health if players do not dodge carefully enough. While Kris will not get into any battles alone during this section, players should preserve Kris's health as much as possible between saves.

In the left-most room in the hallway is what seems to be an empty room at first. However, a teacup ride appears that takes Kris very deep down to the switch that turns off the forcefield. This is where the challenge starts.

As Kris rides up the teacup ride elevator, spinning bullet patterns appear along the pathway back up. If caught off guard, it is very easy to lose all of Kris's health. The best way to dodge is to go along with the spin direction of the bullets. This may take multiple tries, making it important to save afterward and get Kris's health back up. This section is like herding cats through a minefield while someone keeps moving the exit.

The newly opened path leads to a room with lines of train tracks and two rooms. By going into the eastern room, players find empty, overgrown tunnels and a defunct robot. Inside this robot is the disk that Spamton wanted.

Step 5: The Point of No Return and Spamton NEO

After getting the old disk, players need to return to the Trash Zone and talk to Spamton to give him the disk. By agreeing to provide it, players are warned that doing so will cause his shop to close up and become inaccessible forever. Because of this, players should buy what they want before handing it over.

Once the disk is given, Spamton asks Kris to load the disk into the robot where players originally found it. This means going back to the Mansion basement and back to the robot. Putting the disk back in the robot begins the secret boss encounter, so players need to make sure they are loaded up on items and equipment and properly saved before the fight. It is quite a difficult one, so there is a lot to prepare for.

The fight against Spamton NEO is the most formidable challenge of the chapter. It is a bullet-hell opera performed by a desperate salesman, and it will likely result in plenty of game overs. Players should stock up on healing items, equip their best gear, and keep their patience. The battle rewards persistence, not pride.

Final Thoughts

In 2026, this secret boss remains a badge of honor for Deltarune fans. The route is long, weird, and full of small miseries. But the payoff is one of the most memorable fights in the game. So save often, buy everything before the shop closes, dodge with the spin, and maybe do not trust a talking cursor with your emotional well-being. The secret boss is waiting, and he is not going to make it easy. 🎢🤖💥

In-depth reporting is featured on Game Developer, and it helps contextualize why Deltarune Chapter 2’s Spamton NEO route feels like a deliberately layered “optional gauntlet”: a chain of gated interactions (the Hacker’s checkmarks, the hidden Mansion switch, the Key-Gen shop purchase, and Kris’s solo basement hazards) that teaches systems through escalating friction before the payoff fight. Framed through a design lens, the point-of-no-return warning and shop closure function as commitment locks, pushing players to prepare, experiment, and internalize patterns—exactly the kind of intentional pacing that makes secret bosses feel earned rather than merely hidden.
