Props Animations is a big collection of animations designed for use in Mecanim that is only going to get bigger.
With over 810 animations and more getting added with requests, this asset is your personal animator
There is also a couple of small 3rd person controller scenes and a layer mask example scene to get you started with setting up your own controllers.
Best of all, if the animation you need isnt in the package, you can contact me via the contact form on the website with the details of what you need for your project and I will add it to the asset at no extra cost.
