Assuming you played the originals on console
I’m not sure if it’s a testament to the visual fidelity of Metro Redux or a stark reminder of how 2033 and Last Light looked on legacy consoles, but this trailer shows that the upgrade for the remake is quite significant. All the different game modes, and new areas and encounters are certainly welcomed additions. However, it’s the side-by-side comparison that really drives home how much better Redux looks to be than the originals.
