Ammaar Reshi, Lead Product & Design at Google AI Studio, used Claude Code combined with Fable 5 to port Command & Conquer iOS. The first build shipped in 40 minutes, followed by a few hours of debugging over two days. The game runs natively on ARM64 iPhone and iPad, with campaign, skirmish, and Generals Challenge intact.
Key Takeaways
- Claude Code + Fable 5 ported Command & Conquer iOS with a first build in 40 minutes and a few hours of debugging over two days.
- The port covers the 2003 PC original (DirectX 8) and runs native ARM64 on iOS with touch controls, no emulator.
- The demo comes from Ammaar Reshi at Google AI Studio, who publicly acknowledges the value of Anthropic’s tools despite the competitive context.
A Complete Port Done in One Agentic Evening
Ammaar Reshi posted the demo yesterday. The Lead Product & Design at Google AI Studio used Anthropic’s Claude Code and Fable 5 combo to port Command & Conquer iOS, a real-time strategy game released in 2003 on PC. The first compiled and playable build shipped in 40 minutes.
The full port took a few extra hours of debugging spread over two days. The result runs natively on ARM64 iPhone and iPad. No emulator, no wrapper, no compatibility layer. The binary looks like a game natively compiled for Apple’s ecosystem.
The port includes campaign mode, skirmish mode, and the Generals Challenge, the three pillars of the game. The control system was reworked for touch: no mouse, no keyboard shortcuts, everything running on finger gestures. That’s one of the areas where the AI had to work without an existing template.
The big technical challenge sat in the graphics pipeline. Command & Conquer iOS’s 2003 codebase runs on DirectX 8, Microsoft’s API of the era. iOS only accepts Metal, Apple’s API. Translating DirectX 8 to Metal without an emulation layer required Claude Code to generate several intermediate stages, then Fable 5 iterated on them in a loop.
What This Says About Frontier Code Agents
The port’s speed is not the only interesting point. It’s also the type of task accomplished that moves the frontier. Porting an old game to a modern platform usually requires a human porter with multiple months of DirectX experience AND multiple months of Metal experience. The Claude Code + Fable 5 combo united both skills into a single agent that iterates, corrects, tests, and ships.
Reshi noted the limitations. iPad crashes on extended sessions, memory consumption is high. The game isn’t ready for a commercial App Store release as-is. But the demo proves the direction: at this pace, a studio still paying a team of junior porters is burning salaries that agentic covers for free.
Reshi’s background is worth noting. He is Lead at Google AI Studio, paid to build one of Anthropic’s main competitors. He still publicly used Claude Code + Fable 5 for this demo. His phrasing online: “you can love the AI space and respect the competition while still being fully focused on building the best answer.” The political signal matters too. Meta banned Claude Code for its engineers in late June, while Google has no such public restriction and Reshi’s demo documents the opposite direction.
The demo lands in the middle of a broader agentic wave. Anthropic has been pushing Claude Sonnet 5 with aggressive pricing on agent workflows since late June. The Command & Conquer iOS port is the business card that speaks to devs and studios: what the agent already does in one evening becomes a commercial argument in the next few weeks.

What This Changes Short-Term and Medium-Term
Short-term, indie studios will start publishing back-catalog ports to mobile in volume. The economic barrier to a port drops to a few hours of agentic compute plus a senior dev to validate. PC games from the 2000-2010 era (Command & Conquer iOS, Age of Empires, StarCraft, Diablo II) become obvious candidates for this kind of sprint.
AAA studios will read this demo differently. What used to take 12 to 18 months for a dedicated team of porters now compresses to a few weeks of setup plus agents running in loops. The remake and remaster calendar tightens. Senior porters keep their value, junior porters will feel the squeeze first.
Medium-term, the licensing question is about to explode. Reshi’s demo runs because he has access to the source files or the binaries. A dev who tries to port a game without the rights will hit the same law as before, in an accelerated way, with tools that make code reproduction trivial. Publishers will likely tighten their DRM and their no-porting policy.
The cleanest signal: the Command & Conquer iOS port did not require a DirectX engineer or a Metal senior engineer. The agent handled the cross-competence stretch. That level of skill blending used to be reserved for specialized porting studios. It now sits within reach of an individual with a laptop and a Claude Code Pro subscription. The democratization of porting changes who can ship what on which platform.
