Pyro

Pyro is an achievement in Metro 2033 and Metro 2033 Redux, awarded for obtaining certain amount of kills with the Flamethrower.

Overview
This achievement is awarded for 5 flamethrower kills in Metro 2033, and 30 in Metro 2033 Redux. In Metro 2033, the flamethrower is only found on Dark Star - Artyom and the other Rangers are attacked by Nosalises, so this is easy to unlock. In Metro 2033 Redux, a portable version of the flamethrower exists (similar to the one from Spider Lair) and it carries over to D6 as well.
