Metro 2033 Redux and Metro Redux [ What's the difference ] ?

Solution
There is no "Metro Redux" unless that is referring to both games redone, as in:

Metro 2033 Redux, and
Metro Last Light Redux

Metro 2033 runs a lot better as they used the knowledge learned partly from Last Light to redo some code. It also isn't nearly as DARK (visually) which bothered some people.
Metro 2033 were released a couple of years back, REDUX is simply an upgraded version with better graphics.
Metro 2033 REDUX is, as the name suggests, Metro 2033.
Metro REDUX (I suppose this is a pack with 2033 REDUX and 2034 REDUX.)

well, thank you all. So you say that the Metro Redux is a pack of the 2033 and Last night, but with enhanced graphics, as well as the 2033 Redux, who's only one game. Would choose all as best answer so to be fair i won't choose anyone :*
