Let me get this straight, this game is Metro 2033, but re-mastered?
So if you've already played through Metro 2033, don't bother?
yup, the reduxes (from what I can tell so far) are almost the same as the original games but with differences to graphics (both re-done on an upgraded 4A engine), plus the following:
Ranger Mode is included in both games.
Each title can be played in one of two difficulty modes: Survival or Spartan. Survival is modeled after Metro 2033, having more limited supplies and ammunition, lower reload speeds and tougher enemy AI. Spartan makes the game more action-oriented and gives players more resources, in the style of Metro Last Light.
More realistic weapon handling; both games track whether or not there is still a round in the chamber when reloading.
Nvidia Physx effects have been re-built with the 3.X SDK.
So not much really unless you haven't played them before (like me as the original engine made me puke) or your a hardcore fan.
