Epic Games Said 'No More Handwritten Code' and Shipped a Buggy AI Launcher to Prove It
Epic Games is going all-in on AI development, and it's not being quiet about it. In the span of a few days, the company publicly bragged that its new launcher was "vibe coded" with AI, claimed it boots 46% faster than Steam, and then watched the backlash roll in as users started cataloguing the bugs. At the same time, Bloomberg reported that Epic has told developers working on an unannounced Star Wars and Marvel shooter that there will be "no more handwritten code" on the project. That's not a policy suggestion. That's a mandate.
Let's start with the launcher. "Vibe coding" is the practice of prompting an AI to generate code rather than writing it yourself, iterating on the output until something works. Epic shipped a preview build of a new launcher built this way and led with the performance stat. And honestly, 46% faster than Steam is a real number worth talking about. Steam's launcher is a bloated relic and everyone knows it. But the bugs users found almost immediately undercut the whole victory lap. When you skip the craft to chase the benchmark, sometimes you get both the number and the mess.
The Disney shooter story is the more consequential one. Mandating AI-only development on a live project with a real team is a different kind of statement. It signals that Epic isn't just experimenting with AI as a productivity tool. It's restructuring how games get made at a foundational level. Developers, predictably, are not thrilled. The concern isn't just about job security, though that's obviously part of it. It's about what gets lost when experienced engineers can't write the code they know how to write. Institutional knowledge, precision, the ability to solve a weird edge case at 2am because you understand the system deeply. AI doesn't have that.
To be fair, AI-assisted development isn't inherently bad. Plenty of developers use Copilot and similar tools to speed up repetitive work, and that's fine. The issue is the word "mandate." Removing human judgment from the process entirely, especially on a game tied to two of the biggest IP portfolios on the planet, is a gamble with someone else's money and a lot of people's jobs.
There's also a precedent problem here. The developer of a mostly-negative Steam game recently came out in favor of more vibe-coded games, which is the kind of endorsement that should give everyone pause. When the loudest voices cheering for AI-first development are the ones whose AI-first products already failed, that's worth sitting with.
Epic is one of the most influential companies in the industry. Unreal Engine powers a huge chunk of what gets made. When Epic normalizes something, the rest of the industry watches. If this works, you'll see other studios follow. If it doesn't, the people who pay the price won't be the executives who made the call.
