Where and How to Use the Mysterious Key in Far Cry 6 to Find the Fuck Anton Rifle

Far Cry 6 is the latest open-world shooter from Ubisoft featuring colorful villains. This time, players are tasked with overthrowing Anton Castillo, a dictator ruling the island nation of Yara. Along the way, you'll face numerous enemies, against whom using particularly powerful weapons is advisable. In this guide, we'll tell you where to find the mysterious key and how to use it to gain access to a unique rifle.

In Far Cry 6, you'll encounter dozens of weapon types, from bows and pistols to rocket launchers. These can be looted from enemies or purchased in stores, but especially valuable weapons will require some searching. Among them is the Fuck Anton rifle.

The mysterious key is an item you'll receive during the «Fetch Quest» mission. Simply complete it — a dog will lead you to this key. Picking it up is one of the objectives of this side quest, so you definitely won't miss it.

The «Fetch Quest» mission is available at Montero Farm. Access to it opens after the «Who's the Good Boy?» mission. Both missions are related to the dog Chorizo. Start by completing the initial mission titled «Meet the Monteros.» After its completion, a new camp will open where you'll meet the dog.

With this key, you'll be able to unlock a chest on the island of Guau-Guau, which is mentioned in the item's description. It's located in the Isla Santuario region. We've marked its exact location on the map.

In the chest, you'll find an automatic rifle named «Fuck Anton.» This is one of the 49 unique weapons available in the game in a single copy. Even if you're not planning to collect them all, this rifle will be an excellent choice in the early stages of the game.
