What is Spamton NEO Fight Simulator?
Spamton NEO is a secret boss (and the final boss of the Snowgrave/Weird route) in Deltarune Chapter 2. This web-based simulator faithfully recreates the frantic bullet hell mechanics, the unique yellow SOUL shooting gameplay, and the iconic soundtrack of the original fight.
Battle Mechanics
- Yellow SOUL (Shooter): You can fire small pellets rapidly or hold the button to charge a massive BIG SHOT. This is required to destroy certain obstacles.
- Pipis and Phones: Spamton will launch destructible hazards like blue eggs (Pipis) and flying phones. Use your shots to clear a path.
- Heart Attack: During specific phases, Spamton's chest opens to reveal his heart. You must shoot it repeatedly while dodging defensive projectiles to progress.
Tips for Defeating Spamton NEO
- Charge Your BIG SHOTs: Holding the shoot button releases a large, piercing shot that destroys multiple hazards at once. Use it to instantly clear out Pipis before they hatch into smaller heads.
- Focus on the Phones: When he attacks with flying phones, prioritize destroying them quickly before they emit soundwaves that restrict your movement.
- Stay Mobile During Heart Attacks: When his heart is exposed, keep moving in a wide circle to dodge the incoming bullets while firing continuously at the center.
- Big Shot Glitch: In the original Deltarune, pressing Enter and Z simultaneously fired massive rapid shots (a known bug). This simulator may or may not replicate that specific glitch, so rely on standard charged shots!
- Watch the Strings: Depending on the route you are simulating, you may need to focus on cutting his strings using the ACT menu rather than fighting him directly.
Frequently Asked Questions
Is Spamton NEO from Undertale or Deltarune?
He is from Deltarune Chapter 2. Deltarune is a follow-up game by Toby Fox set in a different universe, though it shares many thematic elements with Undertale.
How do I use the BIG SHOT?
Hold down the Z or Enter key to charge your SOUL, then release it to fire a large, powerful projectile that pierces through destructible obstacles.
Why does the yellow SOUL work differently here?
In Undertale (like the Mettaton EX fight), the yellow SOUL fired automatically or with a single press. In Deltarune, the yellow SOUL was updated with a charging mechanic.
Should I FIGHT or use ACT to cut his strings?
It depends on your goal! Fighting him depletes his HP and ends the battle violently (standard for the Snowgrave route), while cutting his strings via the ACT menu pacifys him (standard for the normal route secret boss).
Can I play this on my phone?
This web version is optimized for desktop keyboards. You will need arrow keys and Z/X to move and shoot, which requires a physical keyboard.
