Ultimate Guide to Sans' 24 Attack Patterns: Master the Bad Time

on a month ago

In Undertale’s genocide route finale, Sans unleashes 24 unique attack patterns that challenge players’ skills. This guide breaks down each pattern to help you master the battle in the Bad Time Simulator.

SOUL Mode Mechanics

Sans manipulates your SOUL’s movement:

  • Blue Mode: Gravity-based jumping, dominant in the first half.
  • Red Mode: Free movement, used in the second half.
  • Mixed Mode: Rapid switches between modes, requiring quick adaptation.

Opening Sequence: “Strongest Attack”

Sans opens with a punishing combination:

  1. Gravity Slam: Blue SOUL pulled downward with a red warning, followed by bone waves.
  2. Corridor Rush: Red SOUL navigates a narrow bone corridor with obstacles above and below.
  3. Gaster Blaster Combo: Four Gaster Blaster sequences:
    • Edge blasters cover all four sides.
    • X-shaped blasters fire from corners.
    • Edge blaster pattern repeats.
    • Large blasters from left and right, with safe zones at top and bottom.

First Half: Attacks 1-12

  1. Bone Lines
    Sixteen bone rows from both sides, requiring eight timed jumps. Short bones below, tall bones above.

  2. Blue Bones
    Twelve alternating obstacles:

    • Left: Long blue bone, then short regular bone (×6).
    • Right: Short regular bone, then long blue bone (×6).
    • Tip: Stay still for blue bones to avoid damage.

  3. Random Bone Lines
    Unpredictable bones from both sides at varying speeds/heights, requiring 3-6 jumps.

  4. Platforms 1
    Three green platforms above a bone field. Dodge three bones above the third platform, ending with a tall vertical bone.

  5. Platforms 2
    Seven green platforms, right to left. Bones appear above platforms 4-6; final platform flanked by bones from upper-left and lower-right.

  6. Platforms 3
    Bidirectional platforms with bone barriers. Lower platforms move right, upper platforms left, requiring precise timing.

  7. Platforms 4
    Mobile platform above a bone field with three mid-air bone groups. Central bones descend, outer bones ascend.

  8. Horizontal Bone Slides
    Synchronized waves: small bones from left (bottom), large bones from right (top), forming a rhythmic dodge pattern.

  9. Platforms with Gaster Blasters
    Platforms with horizontal Gaster Blaster beams. Lower platforms move right, upper platforms left, with beams targeting above/below.

10-12. Harder Variants
Intensified versions of prior attacks:

  • Faster bone lines.
  • Denser platform-4 bones.
  • More erratic random bone lines.
  • Quicker bone slides.
  • Frequent Gaster Blaster-platform combos.

False Mercy Trap

After the first half, Sans offers a fake “SPARE”:

  • Triggers bone enclosure across the screen.
  • Drains HP to zero.
  • Displays a high-pitched Dogsong Game Over.
  • Sans taunts about friendship and reset permanence.

Second Half: Attacks 13-23

13-19. Screen Flash Combos
Sans rapidly cycles through attacks with screen flickers, blending multiple patterns across seven sequences (Attacks 13-19). Each sequence may include:

  • Gaster Blaster Patterns: Plus-shaped or X-shaped formations targeting the SOUL.
  • Multi-Directional Bone Waves: Bones emerge from various angles, requiring precise dodging.
  • Remixed First-Half Attacks: Variations of bone lines, platforms, or blue bone patterns.
  • Menu-Disrupting Bone Attacks: Bones interfere with menu selections, reducing HP to 1 (non-lethal).
    These sequences increase in speed and complexity, demanding quick adaptation to unpredictable transitions.

  1. Multi-Angle Gaster Blasters
    Gaster Blasters fire from random angles, similar to Undyne’s spear attacks, requiring constant movement and environmental awareness.

  2. Wall Slams
    The SOUL is slammed against the battle box walls nine times, with bones appearing at impact points. Counter: Hold all directional keys simultaneously.

  3. “Be The Leaf” Pattern
    Flowing bone patterns require smooth, curved movement. Follow the bone curves up and down in a cyclical motion to survive.

  4. 40-Second Gauntlet
    A brutal combination of:

  • Rapid bone arrays from multiple directions.
  • Dense Gaster Blaster formations, including plus/X shapes.
  • Wall slams with bones emerging from both sides.
  • Circular Gaster Blasters that track the player’s movement.

Special Attack: Patience Test

Sans’ final move:

  1. Refuses to end his turn, creating a stalemate.
  2. Falls asleep (“Z” visual cue).
  3. Push the battle box left, then down to reach “FIGHT.”
  4. Early attempts reset the SOUL to center.
  5. Reaching “FIGHT”: Sans dodges the first hit but is struck by a second.

Final Defeat

On hit, Sans:

  1. Takes 9999999 damage despite dodging initially.
  2. Leaks a red substance.
  3. Gives a final warning.
  4. Mentions “Grillby’s” and Papyrus.
  5. Exits with a dust sound.
  6. Player’s LOVE rises to 20, HP to 99.
