Alliance SR2 Shepard's Cabin mod is an add-on for the game Alliance SR2. It allows you to create a new room and place within the game. The mod is based on the Shep character from the game, and as such, changes the appearance of a few items, including the desk, bed, chair, and lamp. The only items that are changed are those that are in the room, and all other items remain unchanged. The download is a zip file that contains the mod in the.tpf format. This is a file format that can be used with Texmod or ME3Explorer's TPF Tools. Due to the finality of using TPF Tools, you would suggest trying the mod out with Texmod before committing to this method.
