Owners of the PC version of The Witcher 2: Assassins of Kings (who got their copy via Steam), are eligible to enter an entertaining competition, where the prize is to make an appearance in CD Projekt Red's next game.
All you have to do to enter is have a copy of the game, bought on Steam, and send in pictures of yourself with a short explanation of why you should be in the game (the use of props and costumes is encouraged).
To enter, visit the Face in the Game website, watch the explanatory trailer, and submit your entry.
If you don't have a copy of the game, fret not, as buying a copy of it (again, via Steam) before September 30 will also entitle you to enter into this amusing competition.
