Today, we’re reintroducing Nuke to the Active Duty map group, and moving Inferno to the reserves. Nuke will be featured as one of the seven maps played at the CS:GO Major Championship at ESL One Cologne 2016

CS:GO is running an experiment to find out whether players will have a better matchmaking experience when they are matched with players who are using a phone-linked CS:GO account.

To join the experiment, you'll need to upgrade your CS:GO account to Prime status. Just click the UPGRADE button below, which will bind your Steam phone number to your CS:GO account (provided it qualifies, see the F.A.Q. below).

If you own multiple CS:GO accounts, be sure to upgrade your favorite one since you can only upgrade one CS:GO account to Prime status with your qualifying phone number.

Once there are enough Prime accounts, we will begin Prime Account Matchmaking and will start prioritizing matching Prime status players with each other.

There's nothing else you need to do (except convince your friends to click that Upgrade button too so we get enough players to start testing!)
