Description

Der Koloss is a high-fidelity browser-based wave survival game featuring solo play, four-player co-op with voice chat, wonder weapons, and perks. The project is a 'one-shot' transformation of a previous game codebase, achieving a complex 3D multiplayer environment through a single prompt.

Prompt

I want you to fork this zombie project directory, and I want us to make the environment, the map, and the gameplay look AAA, just like this tweet (screenshots attached for visual reference): https://t.co/b5CzKRTbVt

Right now, the game you'll see is very blocky and not realistic... I want it to look like Battlefield 6 or the latest Call of Duty, with motion blur, amazing shadows, lighting, microanimations, and all the other bells/whistles that differentiate a vibe-coded game from a studio-level game.

I want the map and gameplay and logic to effectively stay the same, but the visuals and movement need a huge update.

Let's not edit this directory directly. I just want you to fork it and then redo everything graphics-wise:
* visual theme
* movement
* all the models
* etc

If you need new sound effects, you can do it with ElevenLabs, and you can even do new music with ElevenLabs or text-to-speech, anything. You can also use the ElevenLabs library of sound effects we already have as well. Whatever's best.

For the 3D modeling of the zombies, the gun, that map, the lighting, everything, the motion blur, the movement systems, how smooth it is, how your camera shakes when you run, all that stuff: that's gotta get to that level of quality of latest Battlefield/COD.

Work until you are done. Test using browser if you need. And just have many recursive loops until its fully up to AAA standards.
