How It Was Made
Built With AI, In A Single Day
This whole game - code, art, music and voice - was created with AI tools in one day, right here in Kota Kinabalu. It's the same workflow we teach in our programs.
Claude Wrote The Code
Anthropic's AI coding agent built the whole game - fighting engine, combos, CPU opponents and even the online 1v1 multiplayer - from plain-English instructions.
Higgsfield Made The Art
Every fighter sprite, animated stage, super-move effect and piece of key art was generated with Higgsfield AI - no stock assets, no illustrators.
AI Music & Voice
The retro chiptune soundtrack, the sound effects and the arcade announcer voice were all AI-generated to match the 16-bit vibe.
Shipped In One Day
Idea to a live, playable, shareable browser game in a single day - 12 July 2026 - by the NextGen team in Kota Kinabalu, Sabah.
If a training academy in KK can ship a real game in a day with AI, imagine what these tools can do for your everyday work. This is exactly what we teach in our Vibe Coding program.
