How to Play GIGA Queen Fight Simulator
Climb into the cockpit of your colossal mecha and prepare for the ultimate Cyber World showdown in the GIGA Queen Fight Simulator. This fan-made boss battle reimagines the monumental clash between Kris and Queen from the climax of Deltarune Chapter 2. Instead of the multi-phase arcade boxing match from the official release, this browser-based simulator adapts the colossal mecha confrontation into a full-scale tactical bullet-board battle, pitting Kris in the Thrash Machine against the towering Mecha Queen.
In this high-stakes duel, Kris pilots the Thrash Machine solo with a robust 200 HP pool, standing toe-to-toe with GIGA Queen's massive 4500 HP health bar. The encounter is divided into strategic turn phases. During the player turn, you select your actions from the bottom command deck, utilizing FIGHT to deal direct physical damage with your mecha's weapons, ACT to interact with Queen's eccentric personality, ITEM to restore depleted health, or DEFEND to brace for incoming impacts while generating bonus Tension Points (TP).
When GIGA Queen launches her counteroffensive, the combat arena expands across the cyber highway. You maneuver your SOUL through heavy volleys of computerized projectiles, tracking missiles, exploding diamond formations, and giant battery-acid glass attacks. By skimming projectile hitboxes without taking direct hits, you steadily fill the TP gauge on the left side of the screen, unlocking game-changing tactical options and high-powered counterattacks.

What Is the GIGA Queen Fight?
At the dramatic conclusion of Deltarune Chapter 2, Queen unleashes her ultimate mechanical creation: GIGA Queen (also widely recognized by the community as Mecha Queen). Towering over Cyber City, this titanic robotic suit reflects Queen's eccentric vanity and overwhelming computing power. In the official game, the confrontation is staged as an elaborate tribute to classic arcade boxing games, complete with ducking, blocking, and super punches.
The GIGA Queen Fight Simulator takes that iconic confrontation and translates it into the traditional, beloved bullet-hell battle system of Deltarune. Created by dedicated community developers, this simulator captures the visual spectacle of the highway mecha duel while delivering the nuanced pattern-memorization and tactical resource management that Deltarune combat fans adore. The project faithfully showcases custom animated sprites of GIGA Queen laughing, charging laser cannons, sipping battery acid, and smashing the battlefield with mechanical gauntlets.
Fighting GIGA Queen in this format offers a completely fresh tactical challenge. Without Susie and Ralsei present in the party, Kris must balance every single turn between dealing sustained damage to Queen's 4500 HP pool and maintaining defensive positioning. It serves as both an exciting alternate universe take on the Chapter 2 finale and a rigorous training ground for players testing their dodging reflexes.
GIGA Queen vs. Mecha Queen: The DELTARUNE Boss
This simulator faithfully incorporates the escalating intensity of the Chapter 2 boss encounter across distinct combat rounds. GIGA Queen's behavior evolves as her health decreases, forcing you to adapt your defensive maneuvers to increasingly complex attack configurations.
During the early combat turns (Round 1), Queen tests your piloting fundamentals with geometric card-suit barrages. Clusters of spade projectiles rain down from the top of the board, followed by exploding club shapes that fragment into bouncing spheres. In this phase, Queen periodically sips from her battery-acid glass, creating brief openings where players can focus on landing perfect hits on the attack bar to steadily chip away at her armor.
As the battle progresses into Round 2 and Round 3, Queen intensifies her mechanical arsenal. She activates heavy missile salvos that home in on the Thrash Machine's coordinates, along with horizontal laser sweeps and sweeping punch strikes that restrict the walkable area of the combat arena. Queen also triggers temporary barrier sequences where her defenses spike, requiring players to choose between bracing with DEFEND to conserve HP or executing precise ACT commands to break her momentum.
Managing the Tension Points (TP) gauge is paramount to surviving the later stages of the fight. While standard attacks build minimal TP, daring players who position their soul close to Queen's missile trails can rapidly charge the meter to 100%. Maintaining high TP allows you to execute powerful combat abilities or deploy crucial defensive shields before Queen unleashes her most devastating full-screen attack sequences.
Tips for Beating GIGA Queen Fight Simulator
- Anticipate the Missile Tracking: When Queen deploys homing missiles, do not dart erratically around the board. Move in wide, circular motions along the arena perimeter to lead the projectiles into safe detonation paths behind your soul.
- Exploit the Battery Acid Openings: Watch for Queen's signature laughing and drinking animations. These moments telegraph turns where incoming projectile density is lower, giving you the perfect opportunity to commit to aggressive FIGHT commands rather than wasting turns on healing.
- Use Defend on Multi-Hit Rounds: Because you are fighting solo without Ralsei's healing spells, your HP pool of 200 must be guarded carefully. If you enter an attack turn with less than 60 HP, always choose DEFEND to halve incoming collision damage and boost your TP gain.
- Master the Attack Bar Timing: GIGA Queen possesses a colossal 4500 HP pool. Landing off-center hits will drag the fight out for dozens of rounds, increasing your risk of fatal errors. Focus on the rhythm of the sliding attack cursor to consistently land critical strikes.
- Stay Low During Diamond Generator Waves: When diamond-shaped generators appear near the top of the box, position your soul in the bottom third of the arena. This grants you maximum reaction time to spot the safe gaps between expanding laser beams.
