Aeterna Noctis: Virtuoso Review (Xenthoxin)
64 hours, completed (109%) the game and noticed many achievements I didn't have. 0 Game crashes. Great game.
Oh, it has DLC. Oh, it says I can use this to get the achievements from bosses I missed, like beating without using Arrows! Sweet. Beat the boss multiple times, on Hard, even unbound the arrow key, didn't get hit (didn't use bubble either) did not unlock the achievement.
DLC Crashed multiple times loading the boss fight (after screen goes black to load from pressing "B" at the mirror to start, after selecting perks and gems, so you have to do that all over again. To add insult to injury, when you load back into the game, it will be sure to tell you, Challenge Failed :))
Don't buy this DLC if you're hoping to get achievements from the main game, even though it straight up says that it can be used that way. Very frustrating.
