Developer 4A Games has released Linux and SteamOS versions of its first-person shooters Metro 2033 Redux and Metro: Last Light Redux.

Both games support Steam Play, so if you've already bought them the Linux and SteamOS versions have been automatically added to your Steam library.

"Thanks to huge advances in driver support, the Metro Redux titles were developed for Linux using OpenGL 4.0," chief technical officer at 4A Games Oles Shishkovstov said. "This has allowed us to deliver an experience that rivals the DX11 version for Windows in terms of graphical fidelity and performance - something that was just not possible when we ported the original Metro: Last Light to Linux a year ago."

4A Games, which developed the Linux versions itself, says that Linux users can expect all the graphical features and options the game has in the DirectX 11 version including SAA, Motion Blur, and Nvidia's branded PhsyX, if you own a card that supports it.

A mac version of the games that's based on the same OpenGL 4.0 will release on Steam later this month.

Here's what you need to run the game on Linux:

Minimum:

• OS: 64-bit Ubuntu 12.04 or 14.04 or Steam OS
• Processor: Intel Core i5 2.7 GHz (or equivalent AMD)
• Memory: 4 GB RAM
• Graphics: NVIDIA Geforce 460 / AMD 5850 with 2GB VRAM
• Open GL: OpenGL 4
• Hard Drive: 10 GB available space

Recommended:

• OS: 64-bit Ubuntu 12.04 or 14.04 or Steam OS
• Processor: Intel Core i7 2.5 Ghz (or equivalent AMD)
• Memory: 8 GB RAM
• Graphics: NVIDIA Geforce 680 / AMD 7870 with 2GB VRAM+
• Open GL: OpenGL 4
• Hard Drive: 10 GB available space

If you haven't played the Metro games on PC before, they're beautiful, and these official Linux versions make them some of the better looking games for the open source operating system you can get through Steam.

The Redux editions, which were released earlier this year, are even better looking versions of the originals, upgraded to use 4A's latest engine.
