FREE UNITY ASSETS MEGA LIST
This page contains a curated list of high quality FREE tools and models to kick start your Unity game - with over 150 assets and growing!
I have also started a CHEAP (less than $15) asset list - these are assets that I have either used with GAIA or that have been recommended by the community. They are particularly useful when you want to step things up a level. Who said that you needed to spend a lot of money to become productive with Unity 3D!

I hope you enjoyed this list. In return I would really appreciate it if you would also take a moment and have a look at GAIA. GAIA allows your to design your scene to suit your game - not your game to suit your scene and with over 150 different terrain stamps included plus a decent collection of game ready assets it can create anything you want in minutes. Gaia can leverage a bunch of the assets included on this page. Ahem.. and no GAIA is not free ;)
