A new six-minute trailer walks through the visual and gameplay improvements fans can expect from both sides of Metro Redux.
Metro 2033 Redux received the most immediately noticeable alterations; global lighting and improvements to level geometry make the surface world seem more cold and vast, and combat takes a page from Last Light's improved weapon handling and AI.
It also features several new hidden areas and encounters, and a more seamless story with fewer load screens.
Fans who missed the slower-paced tension of Metro 2033 can play Metro: Last Light Redux in Survival mode, while Spartan mode offers a more action-heavy experience in both games.
Metro Redux will release on August 26 in the US and August 29 in Europe. Metro 2033 Redux and Metro: Last Light Redux will also be available separately as downloads.
