This is a Unity and Unreal Engine focused skill that handles the full stack of game development work, from character controllers and combat systems to multiplayer networking with Mirror and Netcode for GameObjects. It covers performance optimization (shaders, LODs, occlusion culling), level streaming, and VR/AR implementation with OpenXR. The skill also builds custom editor tools, which is honestly one of the more practical inclusions since that's where a lot of dev time gets saved. With 225 installs and passing security audits, it seems solid for prototyping mechanics or tackling graphics bottlenecks. Best suited for developers working in commercial game engines rather than custom engine development.
