Due for release in a couple of weeks, a detailed video of Metro: Redux has been released, showcasing the many changes and improvements for the two games (2033 and Last Light).
It’s fairly clear that this isn’t a simple rehash of some textures. Actual work has gone into Redux, with many improvements in not only graphical, but gameplay. Most remarkably, the much improved stealth and combat mechanics in Last Light have been fully implemented into 2033, which suffered from immense AI and stealth issues.
Due for release 28th of August, Metro: Redux can be bought on the Xbox One, PS4 and PC. PC owners get a 50% discount if they owned previous versions.
