About five dozen images, purportedly from an alpha test of Battlefield 4's Xbox 360 version, found their way onto the Internet early this morning. A thorough deconstruction of their contents, by Reddit, give up weapons, vehicles, player classes and other details, though being an alpha version, any of that could change.
Their origin is unknown, other than a watermark across each image, but several of the screens reference the alpha test, a few refer to PartnerNet, the developer-only Xbox Live network where games are tested pre-release, and one invokes confidentiality agreements. Whoever pulled the screenshots apparently had access to PartnerNet and found the alpha, which was concealed by DICE when uploaded.
The images appear to come from a multiplayer test on a map called Siege, which is set in Shanghai. It's unclear, but working elevators may also be a map feature. Other features alluded to in the image include pistol, knife and grenade customisation, dual sights, and battlepacks, which had been rumoured earlier in a focus-group survey about the game. Battlepacks would contain options like player skins, weapons and other accessories, and would be unlockable with in-game currency (which, presumably, one could also acquire with real money.)
Other new details include loadout and award screens and a new HUD consistent with the one seen in the official video of the singleplayer campaign, released back in March.
I've pinged an Electronic Arts representative to confirm or deny these images' authenticity but, given the subject matter and the timing, my guess is we'll have to wait until later this week at E3 to learn more about Battlefield 4.
