It's Just a Scratch

It's Just a Scratch is an achievement/trophy in The Two Colonels, a DLC for Metro Exodus.

Overview
This achievement is obtained after finishing the entire playthrough of The Two Colonels on at least Normal difficulty without using a single Medkit. Unlike in previous games, player's character doesn't fully regenerate his health back after a while when playing on Normal or higher, so getting this achievement might be tricky. A careful approach, engaging from afar and using stealth when possible is recommended. When the player survives an encounter with enemies but gets seriously injured in the process, it is better to reload the last save instead of immediately continuing further.

The achievement is not awarded when you use a Medkit and later load an earlier savepoint. This is important for players trying to unlock Mind You, It's Quite Heavy! together with this in one run.

Trivia

 * The achievement name and icon are a reference to the Black Knight in Monty Python and the Holy Grail.
