Metro Redux contains a multitude of changes that separate it from the original releases, and most of it is noticeable the moment you start playing. For starters, Metro 2033 Redux’s gameplay includes most elements from Metro: Last Light, including the ability to wipe your mask clean by pressing the LS button. Combat also includes Last Light’s stealth takedowns and all the weapons from its prior DLCs. And while the levels have remained about the same, certain characters and items have been given new locations. Some content has been censored, as developer 4A Games omitted the drug references from the original releases.
