This is custom Winchester shotgun. It can be used as a bullet launcher, beacose it doesnt have shell ejection. Instead bullet is a shell(look screens) filled with pellets. For example in your game shell could explode near the target releasing pellets in air.
Model is easy to animate beacose of model structure. Also shell model is filled with pellets.
Avaliable file formats are 3DS, OBJ and FBX. Textures have resolution up to 2024×2024 in JPEG and PNG file formats. Plus normal textures for bump maping.
Model have been also tested in Unity and works well.
