# msattack: reconstructing the Metal Slug Attack backend

> msattack is a Go reimplementation effort for the Metal Slug Attack backend. The author describes capturing traffic between the game and its server to infer private API behavior, then writing a replacement service and proxy scripts. The documented setup also requires game data obtained separately from observed traffic or another source.
