It is not new, but it's first time i play it !
This is a playable level; i don't know if it is Unity 3 or not,
but it runs in a Web Browser really well.
It has Depth of Field, 3rd person Camera and zoom, Next Gen soldier, AAA textures and level with vegetation , water ...

Unity Web Demo

Unity holds all that level and characters really well.

Just do It !!
