As I said on another topic. DON'T BUY THESE KEYS IT'S TOTALLY STUPID! Beta will start in a few days for everyone who entered it. Recieved a mail from Steampowered some days ago asking me to do tests for the beta... Don't waste your money, don't be stupid.
Why do you want to buy key? Beta will start in just some days! I recieved some days ago a mail from steam asking me to do a test for the beta... Just enter in the beta ....
