Bungie has announced that its upcoming game Marathon will not be available on the Steam Deck, a decision that has raised concerns among fans of handheld gaming. This new title, set to release soon, is an extraction shooter themed in the same universe as Bungie's classic game from 1994. While PC players and console gamers on PlayStation and Xbox will have access, those using the Steam Deck to enjoy portable gaming will be left out.This decision comes despite the relatively low system requirements of Marathon, which suggests that technically, the game could run on the Steam Deck. However, Bungie's choice appears to be a strategic one, as they may feel that the handheld market does not align with their objectives or target audience for this title. This raises larger questions about how game developers view the viability of mobile platforms, especially for graphic-intensive titles like Marathon. The fact that other games such as ARC Raiders are compatible with the Steam Deck further highlights this disconnect, leaving many fans pondering why they cannot enjoy Bungie's latest offering on their preferred device.
