NOT UPDATED FOR THE LASTEST UPDATE

Slay the Princess has a very non-linear narrative, so many of the achievements can be unlocked through different routes. I've only detailed one route per achievement, for simplicity's sake.

This guide is organized according to Chapter 2 starts. Basically, any achievement or route stemming from Chapter 2: Adversary will be in the Adversary route tab. Since there are multiple paths through the story this could be confusing, but if something isn't in the tab you expected, just Ctrl + F and search for it. I probably just took a different path than you did :)
