This tree is very low poly, 90 polys to be exact, it still has great detail. It is perfect for a game. It comes with two textures, the leaf, and the bark. You can use this for anything, just do not give it out. This also comes with great flexibility in file formats. I will name the 3 most used. 3ds, fbx, and obj. It has more as well.
To extract you will need 7zip or winrar, and yes, 7zip is free.
