Digiex has leaked shots from several unannounced Arcade games that look set for a release soon, including Sonic Adventure and Crazy Taxi.
The forums also has unofficial shots of the game up and running, as well as Quake Arena Arcade, which was previously confirmed for a release on Xbox Live Arcade.
Last we heard on that was that it was playable at last year’s Quakecon alongside Doom II.
The forums also has a list of other games coming to the service, such as Metal Slug XX, King of Fighter 2002 and Raystorm HD, plus more.
