Wild Card

Welcome to Wild Card, a fan-made combat simulator that plunges you into a chaotic battlefield. Can you survive the suffocating chaos?

Game Overview

Wild Card is inspired by Undertale, and it's not your typical boss fight, it's your own personal battlefield. In this game. you design your own battles. Choose from a deck of Sans-inspired Wild Cards, arrange them in any order, then try to survive the nightmare you've created. With bone attacks, gravity twists, and Gaster Blaster blasts at your disposal, you decide how intense—or forgiving—each challenge is.

What Is Wild Card?

Wild Card is a sandbox combat simulator with no story, no progression system, and no win/loss conditions. It's all about creative experimentation and survival. You are both architect and challenger - set the scene, choose your attacks, then fight through the chaos.

How to Play

• Choose from a variety of Sans-themed cards representing classic Wild Card moves—bone walls, explosive guns, gravity shifts, and more.
• Build your combo chain: drag and drop cards onto your custom timeline. String them together to create smooth transitions or devastating surprise combos. The difficulty is up to you!
• Hit play and fight: Once your combo chain is ready, switch roles from designer to survivor. Avoid all patterns and see how long you can hold your own against your own creation.
