Valve will release the first downloadable content for Portal 2 this summer, according to a recent interview.
Speaking with Fast Company, Valve VP of marketing Doug Lombardi confirmed the DLC.
"We will be announcing some DLC for it, so folks can keep a lookout for more content coming this summer," he said.
It was not revealed whether the DLC would include single-player or co-operative challenges, or a combination of both.
The game received high praise in reviews for its "warm cast that makes you genuinely grin from ear to ear, and a series of trials so perfectly pitched that they are equally challenging and fair".
Portal 2 released on PC, PlayStation 3 and Xbox 360 April 19.
