What if a game had no human developers at all?
That question is no longer theoretical. Codex Mortis has officially launched on Steam and is being described as the world’s first video game created 100% using artificial intelligence, from concept and code to assets and design decisions.
As expected, the response from the gaming community has been intense.
What Is Codex Mortis?
Codex Mortis is an indie PC title built entirely with AI tools. According to its creators, no traditional development pipeline was used, meaning:
- Game logic was AI-generated
- Visual assets were AI-produced
- Systems and mechanics were assembled via AI workflows
The result is a fully playable release that exists less as a traditional game and more as a proof of concept for AI-driven development.

Why Is Codex Mortis Making Headlines?
This isn’t about polish or production value. Codex Mortis matters because it answers a huge industry question:
Can AI build a complete video game on its own?
The answer, technically, is now yes.
However, player reviews on Steam reflect a divided audience:
- Some praise it as a groundbreaking experiment
- Others criticise its lack of depth, cohesion, or human creativity
Both reactions are valid and that’s exactly why this release is important.
What This Means for the Future of Gaming
Codex Mortis does not replace developers, but it changes the conversation.
AI is already used in:
- Asset generation
- Animation assistance
- Testing and optimisation
A fully AI-made game pushes that boundary further, forcing studios and players alike to consider:
- Where human creativity still matters most
- How AI tools should be regulated or credited
- Whether future games will be hybrid creations

Final Thoughts from Respawn Outpost
Codex Mortis may not be perfect, but it is historic.
This is one of those moments the industry will look back on, not because of how fun the game was, but because of what it represented at the time.
Whether you love it or hate it, AI in gaming just took a very real step forward.
