The Zune HD has been out for a while now, but the current news is the Zune Marketplace's addition of five free 3D titles, including our Vans SK8: Pool Service, which garnered some greatreviews in the spring as its original iPhone iteration. Hop over to Gizmodo to take a brief look at the five games available. The new Zune HD edition of Pool Service features a number of tweaks over the original thanks to the device's more robust processor and graphics capabilities, including a new environment, new animations and an smooth framerate of over 50 fps. The game also takes advantage of the Zune's custom playlists, so players can skate to their own tracks.
