Don't fill it out and you won't get a key, says Valve.
Valve has launched a Counter-Strike survey on Steam, with those who complete the form promised the possibility of receiving a Counter-Strike: Global Offensive beta key.
"Over the coming months we will make selections from the survey participants," said Valve on its CS blog. "Sometimes we might add experienced players, other times new players. Sometimes 1.6 players, sometimes CSS players, sometimes people who have played neither.
"There are no wrong answers to the survey questions."
The first batch of keys will be sent out next week. Click here to open Steam and fill in the survey.
Martin says this is the best survey he has ever filled in, so it must be good.
