The game was originally released in 2013, but just a year later, 4A Games (the developer behind the franchise) released a Redux version that features both Last Light and Metro 2033, which debuted in 2010.
Metro: Last Light is a post-apocalyptic-themed, first-person shooter video game with stealth and survival horror elements. It was developed by Ukrainian studio 4A Games and published by Deep Silver for Microsoft Windows, PlayStation 3, and Xbox 360 in May 2013. In 2019 a third part called Metro Exodus was released with support for NVIDIA RTX and DLSS technologies.
