Marathon is a game which will be as familiar to long-time Mac owners as Doom. A sci-fi first-person shooter from the 1990s, it was a Macintosh exclusive which introduced numerous important FPS features. Bungie, the team which developed it, later went onto create the Halo series.
While Marathon has been available on iOS for several years, it hadn’t been updated in half a decade. Fortunately, that all changed recently.
