How to Play DustBelief Papyrus Phase 3 Fight Simulator
Experience the devastating emotional and mechanical climax of the Dustbelief AU in DustBelief Papyrus Phase 3 Fight Simulator. Created by Japanese developer xX_crazy-apple_Xx, this project faithfully adapts Phase 3 of the legendary Dustbelief storyline conceived by Aude-Javel. Having absorbed the souls of the Underground and enduring the phantom guidance of his fallen brother Sans, Papyrus enters his third and most lethal form: gripping an oversized bone quarterstaff, wreathed in roaring determination flames, and driven to end your genocide once and for all. If you have played two-player duels in Dustbelief Papyrus Multiplayer Simulator or faced the tragic hero in Disbelief Papyrus Fight Simulator, this solo trial is a premier test of skill.
Control the Human SOUL using the Arrow Keys. When menu options appear, tap Z to confirm selections or execute attacks, and press X to deselect or cancel menu choices. Throughout the encounter, Papyrus frequently forces your heart into Blue Soul gravity mode: press and hold the Up Arrow key to execute high leaps over advancing bone barricades, and release it for short hops to clear floor obstacles without overshooting into overhead hazards.
Phase 3 introduces relentless attack choreography. Papyrus strikes the ground with his bone staff, triggering sweeping ground spikes, vertical bone stabs (modeled by The_Human_42731), spinning bone wheels, and massive Gaster Blasters (crafted by Jillakatok). The battle features dynamic sprite animations by 悠然自得0607 and MegaDORIN999, paired with Pritxxus Zone's thunderous musical score.
Surviving Phase 3 demands supreme spatial awareness. Papyrus combines vertical floor stabs with horizontal bone waves, requiring you to leap at exact angles while avoiding descending energy beams. Preserving your HP pool through disciplined movement and timely healing choices is the only path to outlasting his unyielding grief.
As the battle reaches its final crescendo, the phantom of Sans begins to unleash rapid blue magic swings in tandem with Papyrus's staff strikes. You must alternate between vertical platform leaps and horizontal micro-steps, keeping your eyes fixed on the color shifts of your SOUL to survive the most intense double-assault in the Dustbelief saga.
Papyrus's staff attacks follow distinct visual and kinetic arcs. A vertical downward strike sends seismic waves racing along the floor, requiring a prompt leap, while a horizontal sweep cleaves through mid-air space, forcing you to remain flat on the ground. Recognizing whether Papyrus is raising his staff overhead or drawing it back laterally gives you a vital fraction of a second to prepare the appropriate evasive maneuver.
Combat and Gravity Navigation Scheme
| Key | Action |
|---|---|
| Arrow Keys | Move SOUL through bullet hell and navigate menu options |
| Up Arrow Key | Jump in Blue Soul gravity mode (hold for higher clearance) |
| Z Key | Confirm menu choices, advance dialogue, trigger FIGHT strike |
| X Key | Cancel menu choice / Deselect / Dialogue skip |
When in blue gravity mode, jump height is variable based on how long you hold the Up Arrow key. Tap lightly for low bones, and hold firmly for tall staff shockwaves.
About DustBelief Papyrus Phase 3
The Dustbelief alternate universe, created by Aude-Javel, imagines a tragic reversal of Dusttale: after Sans fails to stop the human, Papyrus survives, inherits Sans's dusty blue jacket, and takes upon himself the terrible burden of gaining LOVE to save monsterkind. By Phase 3, the mental strain and accumulated power push Papyrus into a state of incandescent determination.
Developer xX_crazy-apple_Xx brought together an extraordinary group of community artists and animators to realize Phase 3 in authentic glory. Featuring custom character sprites by Tad7, fluid animation by 悠然自得0607, blaster engines by Jillakatok, and determination effects by OIMOX, the project captures the scale and emotional weight of a true Undertale finale.
The combat choreography is intricately tied to the driving soundtrack by Pritxxus Zone. Every staff slam, bone wave, and blaster volley syncs to musical crescendos, rewarding rhythmic dodging and deep pattern memorization. It remains one of the most celebrated Japanese Undertale fan releases in the entire community.
The creator's dedication to fair hitboxes and authentic engine physics ensures that every failure is a learning opportunity, making eventual victory deeply satisfying.
By blending intense bullet hell design with the tragic narrative of an innocent brother driven to extreme measures, Dustbelief Phase 3 stands as a towering achievement in fan development. The seamless integration of community assets demonstrates the enduring power and passion of the Undertale community.
Aude-Javel's original story explored themes of grief, corrupted ideals, and the heavy price of determination. By translating those literary themes into visceral gameplay mechanics—where Sans's phantom actively assists Papyrus during battle—xX_crazy-apple_Xx created an emotional masterwork that resonates powerfully with fans of the Disbelief and Dusttale sagas.
Phase 3 Combat Mechanics and Staff Attacks
Face Papyrus's most formidable techniques across Phase 3:
- Bone Staff Slam & Shockwaves: Papyrus slams his bone quarterstaff onto the arena floor, generating dual shockwaves that travel outward along the ground.
- Vertical Bone Stabs: Red warning markers illuminate the floor milliseconds before giant bone pillars thrust upward, demanding rapid lateral relocation.
- Rotating Bone Starbursts: Concentric wheels of bones spin around the perimeter of the box, constricting inward toward your SOUL.
- Dual-Energy Gaster Blasters: Giant blasters charge in rhythmic unison, covering wide sectors of the arena with lingering white beam corridors.
- Blue Gravity Shifts: Experience dynamic gravity manipulation where the floor drops and shifts beneath your heart, demanding continuous jump recalibration.
- Phantom Double Assault: Dodge simultaneous attacks where Sans's phantom summons blue gravity while Papyrus sweeps with his bone staff.
Essential Survival Strategies for Phase 3
Overcome Phase 3 Dustbelief Papyrus with these battle-tested recommendations:
- Watch for Floor Warning Highlights: Before bone stabs thrust upward, the arena floor flashes faint white and red rectangles. Never stand on illuminated floor segments.
- Vary Jump Heights Deliberately: When staff shockwaves advance, tap the Up Arrow just high enough to clear the crest. High jumps trap you in the air when overhead blasters ignite.
- Center Your Position Between Waves: After evading an attack, immediately drift back toward the horizontal center of the arena rather than lingering near the walls.
- Memorize the Pritxxus Zone Music Cues: Attack waves synchronize with drum hits in the soundtrack. Listening carefully lets you predict blaster discharge timing without looking away from your SOUL.
- Use X to Fast-Forward Dialogue on Retries: Hold X when dialogue appears to skip straight into the combat phase, keeping your reflexes warmed up for the action.
- Save High-Tier Heals for the Final Stand: Papyrus unleashes his most intense bone wheel and blaster combination when his HP drops below 20%. Keep your best healing rations ready for that final trial.
