13 October 2026 | 75

Unlocking the hidden encounter in Deltarune Chapter 2 leads players down a creepy questline featuring Spamton NEO. Defeating this challenging opponent requires patience, quick reaction times, and precise execution. Following the necessary steps to locate his secret shop and basement lair ensures your party enters the showdown properly prepared.

Locating Spamton's Hidden Shop and Key Disc

To begin the quest line, players must first defeat Spamton in his initial miniboss encounter in Cyber City. Afterward, travel to the lower alleyway section of Cyber City to find a hidden doorway leading to Spamton's trash shop. Speak with him to purchase the KeyGen item, which unlocks the maintenance elevator inside Queen's Mansion.

Head deep into the basement of Queen's Mansion using the newly acquired KeyGen. Navigate through the hazardous force fields to retrieve the Empty Disk hidden within the central mainframe room. Return to Spamton's shop to transfer his code onto the disk before making the final descent back to the basement robot body.

Preparing for the Spamton NEO Boss Fight

Inserting the Loaded Disk into the robot shell in the basement triggers the intense fight against Spamton NEO. Your soul transforms into a yellow heart capable of firing charged laser blasts, fundamentally altering the standard combat mechanics. Managing TP gains while utilizing Kris, Susie, and Ralsei effectively is crucial for staying alive during high-damage attack patterns.

Players can choose between a pacifist strategy or a direct violence path depending on their preferred playstyle. Pacifist players must focus on using Kris's Snap command repeatedly while Ralsei and Susie act as primary healers. Combat-oriented players should focus on charged shots and high-damage physical attacks to drain Spamton's health bar.

Mastering Bullet Hell Attacks and Defense

Spamton NEO utilizes a varied arsenal of chaotic bullet hell projectiles, including flying phone heads, giant faces, and pipis bombs. Utilizing charged shots is essential for clearing out incoming obstacles before they reach your soul boundary. Time your movements carefully around his giant face attack, focusing on destroying the eyes, nose, and mouth to reduce incoming damage.

When Spamton initiates his ultimate heart attack, focus entirely on dodging while consistently shooting his heart module to deal massive counter damage. Keeping your health high with items like Tension Tea ensures your team can endure unavoidable hits. Maintaining steady focus during long attack cycles will secure a victorious outcome for your party.

Rewards and Post-Battle Outcomes

Defeating Spamton NEO yields unique armor or weapon rewards depending on whether you spared or defeated him in battle. Winning via mercy rewards you with the Dealmaker armor, which grants massive stat boosts and extra money drops. Eliminating him directly grants the Puppet Scarf, a powerful weapon specifically tailored for Ralsei's offense.
