In this devlog, the creator showcases building a Modern Warfare 2-inspired FPS game using the AI model Claude Opus 4.5 to automate coding tasks like kill tracking, achievements, and reward systems, enabling rapid development of gameplay features and UI updates. They demonstrate how AI-assisted workflows streamline game design, with plans to expand the game to include multiplayer and leaderboards, inviting viewers to try the current version at 360ns.fun.
In this first AI game development log, the creator shares their journey of recreating the feel of classic FPS gaming, specifically inspired by Modern Warfare 2. They focus on capturing the excitement of sniper gameplay, 360 no-scopes, kill cams, and the banter that surrounds such games. Using the new Claude Opus 4.5 model, they have started building a simple FPS game featuring AI opponents, kill cam replays, and basic gameplay mechanics like sniping and knife combat. The game currently supports logging in with a username and tracks basic stats, with plans to expand features and eventually develop a multiplayer version.
The developer demonstrates how they use Opus 4.5’s cloud code capabilities to handle coding tasks, showing a workflow where they instruct the AI to add new features such as tracking kills by weapon type (knife vs. gun). The AI analyzes the existing codebase, creates a plan for implementation, and executes it, including updating the database to store new stats. This process highlights the power of Opus 4.5 in automating complex coding tasks, allowing the developer to focus on game design and feature planning rather than manual coding.
After successfully implementing weapon-specific kill tracking, the developer moves on to creating an achievements system. They add an achievements page to the game menu, where players can see progress towards goals like getting 10 knife kills. The system also includes in-game popups to notify players when they unlock achievements. The developer uses the same AI-assisted workflow to plan and implement this feature, demonstrating how Opus 4.5 can handle both backend database changes and frontend UI updates seamlessly.
The final major feature added in this update is a reward system tied to achievements. Specifically, unlocking a gold knife skin after achieving 10 knife kills. The developer tests this feature thoroughly, showing how the game updates the player’s inventory and reflects the new weapon skin both in gameplay and kill cams. This milestone marks a significant step in the game’s development, showcasing a fully integrated progression and reward system powered by AI-assisted coding.
Overall, the developer expresses enthusiasm for the project and the tools they are using, especially Opus 4.5, which has enabled rapid development and iteration. They invite viewers to try out the game at 360ns.fun, noting it works best on computers rather than mobile devices. Looking ahead, they plan to add more achievements, a global leaderboard, and multiplayer functionality. This devlog serves as an inspiring example of how AI can accelerate indie game development and bring creative visions to life efficiently.
