Microsoft has previously discontinued the $1 Game Pass trial for the first month, but good news is that they have recently launched a new Game Pass referral program. Starting now, players who have subscribed to Xbox Game Pass Ultimate and PC Game Pass can send up to five friends a 14-days free trial, available for new Game Pass users only.
In addition, Microsoft has also announced the May lineup of XGP games, including Redfall, Ravenlok, Weird West, Shadowrun Trilogy and Fuga: Melodies of Steel 2. If you haven't tried the Game Pass service yet, why not try asking for referral from your friends?
