Is it possible to play Halo Infinite without an Xbox Game Pass subscription?

Yes, one can absolutely play Halo Infinite without possessing an Xbox Game Pass subscription. The game is released as a standalone title and is available for purchase individually on platforms such as the Xbox Series X|S, Xbox One, and through the Microsoft Store for PC. Players can choose to buy either the physical disc or a digital copy outright. Additionally, as a testament to its accessibility, the multiplayer portion of Halo Infinite is offered free-to-play, meaning that players across supported platforms can download and engage in multiplayer battles without any upfront cost. Therefore, owning an Xbox Game Pass subscription is a matter of convenience and added value through access to a library of games, but it is not a requirement to play Halo Infinite.
