Google AI Studio lead vibe-coded Command & Conquer: Generals – Zero Hour onto iOS using Claude

Ammaar Reshi, lead of product and design at Google AI Studio, has ported Command & Conquer: Generals – Zero Hour to iPhone and iPad using Anthropic's Claude Fable 5 model. He announced the project on X on July 4, and the port is already open-source on GitHub — though you'll need your own copy of the 2003 game to run it.

The port compiles the original engine natively for ARM64, so there's no emulator involved. Campaign, skirmish, and Generals Challenge modes all work, and Reshi built custom touch controls — tap to select, drag to box-select, long press to deselect. It's a direct fork of The Super Hackers' Linux and macOS build, so Reshi is clear that this had "a chain of giants to stand on." The workflow was a genuine human-AI split: Claude handled the C++ code and debugging while Reshi did the playtesting. He'd describe bugs in plain language — "the minimap is black," "I hear chirping" — and the model would fix them. His own summary: "Neither half ships this alone: one of us can't write C++, and the other can't hear the chirping." The project burned through a full Claude Max subscription in two days, putting the token cost somewhere between $100 and $200. Reshi also tried Opus 4.8 with Ultra Code and it couldn't handle the task — Fable 5 appears to be the only model he found capable.

Command & Conquer: Generals – Zero Hour is an expansion to the 2003 real-time strategy game Generals, developed by EA Los Angeles. The broader C&C series has seen renewed interest in recent years, partly through fan preservation efforts and partly through EA's own remastered releases of earlier titles. This port sits firmly in the fan-preservation camp, built on top of existing community work rather than any official EA involvement. The scalability question is real: Reshi is skeptical about porting something like Red Alert 2, since EA is believed to have lost that game's source code entirely. Even when source code exists, studios are unlikely to hand it over to outside developers — especially if a fan port undercuts the commercial case for a future remaster. There's also the question of AI models ingesting proprietary code, which gives publishers another reason to keep their source locked away.

Reaction has been broadly enthusiastic among RTS fans and the AI-developer crowd, with the open-source release making it easy for others to build on the work. Whether this becomes a repeatable template for other classic games depends heavily on source code availability and publisher cooperation — two things that are rarely guaranteed. Notably, Reshi made no mention of attempting the project on Google's own AI coding tools, which is a conspicuous omission given his day job.
