You've heard of Twitch? Right? The game is able to be linked to Twitch in order for your viewers to play along as well. This can be found in the options menu under 'More Options . You need a Twitch vote to get this achievement.

You can also get the achievement with an alt account or from a friend. Set up integration and put either option into chat and it should work (courtesy of @palex00 and @lordjuhca)

During certain levels you will need to choose precise options in order to collect all 8 items in the game. If it does not unlock first time, try a couple more times, or just the last one. It pinged for me at some point so it is working. They are as follows:








Problem Code Item. Option

1.2.02 A Used Syringe. Euthanise

1.2.03 Organs. Harvest Organs

2.1.04 Vegan Cook Book. Kill Child

2.2.01 Credit Card. Subscription Plan

2.2.03 Rosmary Beads. Blame Evil AI

2.3.04 Floppy Disc. Hack

3.3.02 Car Battery. Torture

4.1.01 Red Pill. Red Pill


This may require you to complete the last level multiple times and/or relaunch the game (courtesy of @lordjuhca)

I believe that both @palex00 and @lordjuhca have both achieved this after completing the game and finishing all other achievements.

In every level you are given the statistics of your choice with the percentage of people who chose the same option, and the percentage of choices you made that aligned with the choices by ReadGraves. In order to get 100% alignment in one play through, the choices are:

For those having issues with this popping, @HowToGod has found:
My Collector achievement popped after I got all collectibles and replayed the Red Pill level (Seemed like re-receiving the Red Pill is what popped it).
