Valve just announced that a new beta patch for Counter-Strike: Global Offensive (CS: GO) has been released on Steam. It adds new maps to local match options (de_inferno, de_train, and de_nuke), as well as new weapons (Nova shotgun, Bizon and MP7 SMGs). The patch also adjusted stamina penalties for jumping - it should be easier now to jump up to multiple objects in a row without getting exhausted. Press 'read more' for changelog.
