You should be able to download it from within Visual Studio. Select option "Tools/Extension Manager/Online gallary" (at least in VS 2010) and search for EPiServer.
In Visual Studio 2012 it is Tools/Extension and updates.../Online/Visual Studio Gallery and search for EPiServer.
or download from http://visualstudiogallery.msdn.microsoft.com/4ad95160-e72f-4355-b53e-0994d2958d3e
