The Struggle is like Desperate Escape but without being brutally unfun. It does struggle with difficulty balancing, however, as it lacks a normal mode, with casual being completely trivially easy and survival being beyond annoying. It has a few interesting mechanics, such as needing to hunt animals for continues, represented by food, but otherwise, it's just a trek through familiar levels and locations. It's not particularly interesting otherwise and it feels like filler content. I do like how it fills in some blanks in Revelations 2's story, such as what happened to Evgeny Rebic and how Moira learned to become competent with firearms by the end of the game. Evgeny and Moira have a fun dynamic, one of Revelations 2's writing strengths, and while "young adult versus old man" is not particularly original it is entertaining here. I wouldn't buy this one on its own, but if you already have the complete collection it's worth a go at least since it's less than an hour long.
