Serial Number: Metal Slug — Complete PC is a modern, fully packaged release of the classic Metal Slug run-and-gun series for Windows. This compilation gathers every mainline Metal Slug title and key spin-offs, updated for compatibility with contemporary PCs and bundled with quality-of-life features: controller support, configurable resolutions, save states, and enhanced display options. It aims to let both newcomers and longtime fans play the series end-to-end with minimal setup.
