Leadlight: Gamma is an updated version of the 2010 game Leadlight, an adventure and RPG hybrid with survival horror elements using a text parser. The main additions to the original game are a broader accessibility on desktop and through mobile devices for iOS, a complete reference manual, an interactive tutorial mode, a dynamic and zoomable graphic automap, customisable game interface, extra content to be unlocked including a behind-the-scenes tour mode and easter eggs, a gallery to browse the original Leadlight artwork, a new original soundtrack and an in-app music player along with an option to download the music separately, and an accessibility mode for vision-impaired players using a screen reader mode that includes text descriptions of all standalone images. The game content itself is identical to the original title.
