As I reported yesterday, Dark Matter is an incomplete game, which ends abruptly upon reaching a certain point in the game. The issue has since come to the attention of the retailers at GOG.com, who are now issuing refunds for anyone who wants it.
"It's come to our attention that the gamecard for Dark Matter was not quite specific enough about the nature of the game and, as a result, it may be that some people bought the title with some misapprehensions as to how the game's story would end. Since we don't ever want to sell a game to someone because they believe it is something that it is not, we wanted to let you know about this and let you know what we're doing to make it right," writes GOG.
"If you bought Dark Matter before 21 October 2013 at 15:00 GMT (when we updated the description to where we feel it adequately reflects the game) and you feel that the game wasn't as promised to you, please contact Support and they'll be happy to offer you full refund to your card or, if you''d prefer, games of equal or lesser value to the sale price of Dark Matter (which is $13.49).
"We're sorry if anyone who bought the game isn't happy with the way it was represented, and we hope this makes it right for you guys."
So there you have it. If you bought the game before October 21, you can seek a refund for your purchase or get a game worth equal or lesser value.
