Dota 2. It supposedly includes information from a folder named "ep3." Now wait a minute, stop huffing -- we know, we know -- and hear us out. As reported by Valve fan site Lambda Generation, the Dota 2 beta client has apparently leaked via Vietnam, and eager fans datamined the code for info, apparently plundering a string of code regarding something called "ep3."
As you might imagine, both the dataminers and gaming websites are saying the folder pertains to the comically nebulous Half-Life 2: Episode 3, with the code pointing to two weapons -- an ice gun and a flamethrower -- as well as three "weaponizers" (concrete, liquid, and metal). But wait, why would Valve leave code for another one of its projects in the beta code for Dota 2, especially a project that it refuses to acknowledge exists? In short, Valve's done some similarly cheeky things in the past to promote its games, albeit not nearly as deep as this would be. We've reached out to Valve for word, but don't expect to hear anything official.
