Indie developer Ed Key has released a free update for the PC version of his meditative exploration-based adventure game Proteus, adding in content previously exclusive to its PlayStation 3 and PS Vita ports.

The PC version of Proteus now includes the PSN version's "Wild Islands" feature, which introduces a series of unique graphical flourishes throughout the game's randomly-generated terrain. The feature is unlocked after playing through the game once, and players can adjust the frequency of these new effects or disable them entirely.

Version 1.2 of Proteus also boasts a steadier framerate and improved audio mixing, among other tweaks and bugfixes listed here.
