On November 22, 2005, XBLA was relaunched on the Xbox 360. The service was integrated into the main Dashboard user interface, and the Xbox 360 hard drives were bundled with a free copy of "Hexic HD". Every Arcade title on the Xbox 360 supports leaderboards, has 200 Achievement points, and high-definition 720p graphics. They also have a trial version available for free download. These demos are playable and most of them offer only a fraction of the levels, modes, and content of the full game. A full version of the game must be purchased to allow the user to upload scores to the leaderboards, unlock achievements, play online multiplayer (with a few exceptions), and download bonus content. Several new features and enhancements have been added through software updates including a friends leaderboard, additional sorting options, faster enumeration of games, an auto-download feature for newly released trial games, and "Tell a Friend" messages. The original size limit imposed by Microsoft for Xbox Live Arcade games was 50 MB, in order to ensure any downloaded game could fit on a 64 MB Xbox memory unit. The limit has since been changed to 150 MB, then 350 MB, and now 2 GB, the latter of which is a technical limitation of the system (rather than an arbitrary limit imposed by Microsoft). On September 12, 2012 the 2 GB limit was raised to an unknown number with two titles, "Red Johnson's Chronicles" and "Double Dragon Neon" weighing at 2.68 GB and 2.24 GB, respectively.
