The first major downloadable content for Valve's Portal 2 has unexpectedly already been released, but seeing as it's only available for those purchasing a $140 peripheral, most people won't be playing it this week.
Razer's Hydra, a strange orb-like controller designed for the PC, is shipping with ten custom-built singleplayer levels of Valve's smash hit sequel, all designed specifically for the Hydra's controls.
It's currently available from Razer's store or, more interestingly given it's a piece of hardware, from Valve's store (for US customers) as well. At $140 that's a lot if you just want the ten new levels, but it would not surprise me in the slightest if there were Valve fans keen enough to do just that.
