Martian

Martian is an achievement in Metro Exodus.

Overview
The achievement is obtained by patching up your gas mask with duct tape after it's damaged. The easiest way to obtain it is during the level Moscow, since the player will be engaged in firefights while wearing the gas mask.

Trivia

 * This achievement is an obvious refence to The Martian, a movie based on the novel of the same name, written by Andy Weir. In the movie, the main protagonist finds himself standed on Mars and during a dust storm, his space suit's visor gets damaged. He repairs the visor with a duct tape, same way as Artyom can temporarily fix his gas mask in the game.
