The Two Colonels is the condensation of the darkest and the most disturbing aspects of the Metro: Exodus, extracted into a distinct tragic story, where the ending was pretty much predefined. It is this feeling of entrapment, both in terms of the setting (radiation-contaminated ruins of Novosibirsk) and the predestined storyline that makes the overall narrative so powerful and profound. I am not a huge fan of horror shooters, so was not too excited about the gameplay, but what made me through the few hours of this DLC, was exactly the contagious feeling of duty and determination that Col. Khlebnikov radiated (no pun intended) through the lens of Col. Melnikov.
