Step into this intense Bad Time Simulator AU where Sans refuses to give up! Experience a multi-phase Sans fight featuring Gaster's mysterious intervention. Navigate through escalating battles as your heart soul faces the ultimate test of determination.

Beyond the Final Breath

This Alternative Universe transforms the classic encounter into a relentless three-stage saga. Beyond traditional bullet-hell mechanics, witness how intervention from mysterious forces reshapes the very rules of engagement, creating an entirely new narrative framework.
Evolving Combat Phases
Three distinct stages each featuring unique mechanics and visual transformations:
  • •Initial encounter: Familiar patterns with classic Undertale foundation
  • •Wounded adversary: Desperate attacks with heightened aggression
  • •Final showdown: External intervention fundamentally alters combat rules
Each transition introduces fresh challenges that redefine the encounter.
The Void Scientist's Influence
Dr. Gaster emerges as a pivotal force within this extended confrontation:
  • •Strategic assistance that defies conventional battle logic
  • •Reality-bending abilities that challenge player expectations
  • •Deep lore connections revealing hidden Underground secrets
His presence transforms predictable outcomes into unprecedented scenarios.
Ethical Ramifications
Your initial path selection reverberates throughout the entire experience:
  • •Pacifist route unlocks dialogue-driven resolution opportunities
  • •Genocide path triggers increasingly hostile environmental responses
  • •Hidden watchers evaluate your commitment to chosen philosophy
The Underground itself responds to your moral stance with tangible consequences.
