Some games offer achievements for doing bizarre, intricate things that must be explained in great detail. Fortunately, The Witcher 2 isn’t one of those games. It mainly awards achievements for things you’ll end up doing anyway if you play the game long enough. Every achievement is explained in detail in some other part of the guide, simply in the course of explaining how the game works and what you can do. For this reason, the achievement list here is cross-referenced against the rest of the guide. If you want to know how to get the Backbone achievement, for instance, you can simply flip to the part of the walkthrough that discusses making the kayran carapace armor.
The achievements are identical across the PC and Xbox 360 versions of the game, with one exception. For Xbox 360 players, the Madman achievement is unlocked by beating the game in Dark mode. For PC players, Madman is unlocked by beating the game at Insane difficulty. Players of both versions should find the tips offered in the Dark difficulty guide useful for obtaining this achievement.
