Even a year and a half after its release, Portal 2 remains a completely stellar game. As a keen bonus, there's still downloadable content coming out for it!

Valve announced today that it is releasing a new piece of content for the game titled In Motion, which will be available on PlayStation Network this coming Tuesday. It features an all new single player campaign to work your way through that's specifically built for use with the PlayStation Move, though you can still play with a regular DualShock 3 controller if you prefer.

There haven't been too many details released about the DLC yet, but we have found a trailer that explains some what you can expect.

The DLC will go for $9.99 once it releases, but if you're a PlayStation Plus member, you can snag it for 30 percent off. Definitely not a bad deal if you ask us!
