Over a thousand Natural Selection 2 keys have been deactivated on Steam as part of a move on a massive credit card scam that has cost developers Unknown World over $30,000.
Using stolen credit cards, a group of thieves purchased keys through Steam and the Natural Selection 2 site, then onsold those keys to regular consumers at significant discounts. After the transactions were completed, they then initiated a charge-back on their initial purchases — forcing Valve and Unknown Worlds to not only hand back the money but pay a $22 charge-back fee each time.
“This episode is a prime example of why all gamers need to beware discount steam keys and those offering them,” write Unknown Worlds in their blog post about the incident. “Right now there are only two official places to buy Natural Selection 2; through Steam or through our website via the Humble Store (The Humble Store option is temporarily disabled due to this issue).”
“If you see Natural Selection 2 available anywhere else — like the many sites out there that sell Steam keys at a discount — then you are not buying it from us and there is no way to know if that key is legitimate. As as result, we strongly discourage purchasing from these sites.”
Affected customers are urged to contact the site from which they purchased the keys.
