Metro 2033 Redux hit Steam on Tuesday, and developer 4A Games is still improving how it looks. A 1.2GB day-one patch added volumetric lighting to a few specific scenes in the game. This isn't a dramatic overhaul of Metro 2033 Redux's entire lighting engine: we compared the patched version of Redux to footage we'd previously captured, and noted that most scenes in the game and most light sources looked identical pre- and post-patch. The changes 4A Games have made, though, are striking.
We've embedded a few webm videos below to show off the differences.
4A Games specifically added volumetric lighting —powerful light rays emanating from somewhere in the environment—to a few locations that we checked early in the game. We also noticed that in at least one location, 4A Games added more environmental detail to a scene that had previously been drab and barren.
Eagle-eyed Metro players in the Steam forums and on NeoGAF have noted that volumetric lighting effects present in the original Metro 2033 were missing in Redux when it launched. 4A's patch has added those effects back in some locations, though not all of them, according to posters on NeoGAF. Players have also noted that the PS4 and Xbox One versions of Metro 2033 Redux do not have the lighting effects 4A Games patched into the PC version.
