These are 2 copies of Dark Matter that I already have. I tried testing both of them and I got an error that it wouldn't do any good redeeming them. So, that narrows it down from one of the 2 possibilities of which Dark Matter key it is to only one. Note that there are two games called Dark Matter, 2 years apart from each other, on Steam. know which copy you have before trying to sign up for this raffle if there is a Dark Matter game still in your Steam library, because you may still be eligible. Note that if you have both Dark Matter games already, I will not release the key to you. I will be examining each player's profile first, so players with private profiles will not be eligible.

Key is for Dark Matter(2015) app 345130 on the Steam store page.
