To get the achievement Bayou Fever in Assassin’s Creed Liberation you will have to complete every Bayou Fever related mission. That means collecting all mushrooms and finding all the victims and force-feeding them the mushrooms. Collecting mushrooms is also required as a part of Collector’s achievement.
So it would seem that there is a serious fever all around the Bayou. Random people have fallen victims to it and now they are losing their senses somewhere in the swamps. You are tasked to find them and help them. Help comes in strange ways it would seem as you have to beat the shit out of every poor fellow first and only then feed him or her the remedy.
But AC Liberation doesn’t seem to have a big problem about hurting citizens since eruditos are disguised as simple harmless citizens as well. And they must be ruthlessly killed. Moreover think about the assassin’s coins collection: you literally have to beat or kill people who’ve done nothing wrong besides the fact that they had happened to have the coin that you seek. These are some examples of the ruthless behaviour in AC Liberation, somehow other AC games didn’t target civilians so much. But nevermind that.
Mostly Bayou fever victims and mushrooms are easy to encounter by just slowly getting through the game and completing main mission and side tasks. Since there is no fast travel into random locations in Assassin’s Creed Liberation, you will have to cover long distances on the map just by running. Knowing this, it’s easy to understand that you are quite likely to encounter everything you are looking for at random. However we all have been in a situation when you just can’t find the last remaining piece of something. And in AC Liberation you may encounter the very same problem. Here is the map to help you:
If you prefer something more visual or you still have trouble finding what you are looking for here are all the locations and execution of the Bayou fever mission in Assassin’s Creed Liberation:
