The giveaway coincides with CD Projekt’s Spring Conference, which is being streamed live at 5pm GMT (presumably 6pm BST).

Note that giveaway has nothing to do with the "extraordinary" conference announcement CD Projekt has been teasing.

CD Projekt Red head of marketing Michał Platkow-Gilewski explained to Eurogamer:

"No, there will be no announcement of a new game.”

"But to give you some hints and not to spoil the surprise, CD Projekt RED and GOG.com have prepared something very special for all the PC fans of The Witcher 2 Assassins of Kings, who already have the game, as well as for all those who will buy one any time in the future.”

"It is something really unique," he added.

"More to come on the conference."

What do you guys think it will be?

As a token of appreciation for its fans, who bought 1 million copies quicker than it’s predecessor Dragon Age: Origins, BioWare is offering past and future purchasers of any new edition of Dragon Age II a free digital download of another of its hit role-playing games, Mass Effect 2.

So what the F**K are you waiting for?! Go for this awesome game!! Click on that picture.

And it is working, I got one code for Mass Effect 2! Even if I have it :)
