A new Whack A Gnome Arcade game found under Electronics / MiscElectronics, costs 0. You need Supernatural or a later pack for the Arcade game to show in your game. This comes with Supernatural ( not a hidden or debug item ) but I enjoyed it so much that I thought for those who don't have Supernatural but have any of the later packs, may also enjoy it. Also it's for FREE ! (instead of 750).
