Undertale AU Collecter | Pick Your Poison
Game Overview
Released:August 26, 2025
Arrow keys to navigate, Z to select and fight, X to go back.
Mouse click to select your Sans and Hard mode.
Browse through a rogue's gallery of Sans variants. Each one brings their own brand of chaos - pick your fighter, set the difficulty, and see which version breaks you first.
What's This All About?
Think of it as a Sans battle buffet - you get to sample different flavors of pain before committing to the full meal.
The Collection
Instead of diving blind into random Sans fights, you get a preview of what each AU variant brings to the table. Some throw bones in patterns you've never seen, others mess with gravity, and a few just want to watch the world burn. It's like having a menu at a restaurant where every dish is designed to kill you, but at least you know what you're ordering.
Pick Your Pain Level
Not all Sans variants are created equal, and neither are players. The difficulty system lets you choose between getting your feet wet or diving straight into the deep end:
- •Each AU has its own attack signature - no two Sans variants fight the same way
- •Normal mode for learning the ropes, Hard mode for when you want to suffer
- •Preview each variant's fighting style before committing to battle
- •Switch between difficulty settings to find your comfort zone
- •Every AU brings something new to the table
