This is a skin pack for Swat 3, It contains Marvin The Martian in his UFO and the Raygun used by Marvin. This pack can be used with both single and multiplayer. This mod wasn't made by me, Nor Do I take credit for it, This was originally on the swat3reunited website. Reuploaded here to get interest in swat 3 again.
Place the file into the swat 3 mods file under Sierra/Swat3/Mods, Enable via the Swat 3 mod launcher and the mod will be ready for use.
