Metro 2033 is a first-person shooter game that is set in a post-apocalyptic Moscow - inside the metro system as the name suggests. You will fight mutants or other humans who want to take away your shelter. The game has many gameplay elements similar to STALKER; the engine also has similar features. This is because two STALKER engine programmers left GSC Game World and started their own company which is now making Metro 2033.
The engine has support for all the latest eye candy like DirectX 11 and tessellation. Unfortunately, it leaves a less than satisfactory impression, making it a candidate to surpass Crysis for the highest hardware requirements. We tested the game in DirectX 11 mode with details set to "Very High".
