AchievementHelper
Provides helpful info for Biotracker and The Inner. Also fixes a very rare bug that makes The Voice of Truth and Unmasked unobtainable.Details
Biotracker
Displays a notification the first time an unmarked enemy is killed. For host, the notification also identifies the player responsible.
At any time, you can type /biotracker in chat to see the current status of the achievement. If the achievement is active, this command also reports how many enemies are left on the map.
The Inner
Displays your current progress before and after every game.
The Voice of Truth
When a player reads JN8-M96-M31 in R2E1 Zone 598, the game makes an API call to PlayFab to record that the log was read, and it makes a separate API call to Steam to give credit for the achievement. In rare circumstances, it's possible for the first API call to succeed, but the second API call to fail. When this occurs, the achievement becomes unobtainable, even on subsequent playthroughs.
If this happened to you, then AchievementHelper will retroactively give you credit for the achievement as soon as you launch the game. (It won't give you the achievement if you haven't read the log.)
Unmasked
Same as The Voice of Truth, but for 12 logs scattered across R5A1, R5A2, R5A3, R5B3, and R5C2.
D-Lock Block Decipherer
AchievementHelper doesn't help with this achievement. I still recommend https://andocas.com/gtfo/log-tracker/.
