This contains .blender file which contains the rigged 3d Ninja model with packed textures. download both .blend and .blend1 file so you can get external textures all at once in the .blender file. it is lowpoly perfect for your animation but if you want to import this to game engine you'd have to export the texures and the model which is a good thing because blender is a great too for that task.
If you have any problem feel free to contact me. enjoy
