Fallout 4 is the gift that keeps on giving, and if you want more post-apocalyptic goodness, then you’ll want to check out this free expansion today.

Released in 2015 for PC, PlayStation 4 and Xbox One, Fallout 4 is one of Bethesda’s most popular RPGs, which should come as no surprise when you consider how beloved this series has become over the years.

“As the sole survivor of Vault 111, you enter a world destroyed by nuclear war. Every second is a fight for survival, and every choice is yours. Only you can rebuild and determine the fate of the Wasteland. Welcome home,” reads the synopsis of Fallout 4.

In its own right, Fallout 4 – which benefited from a free new-gen update earlier this year – is a game with tons of replay value, with its huge open-world and many expansions included in its official season pass.

However, thanks to the ever-vibrant modding community, new life is continually injected into the game, intensifying that replayability further.

One such mod is available to download for free right now via NexusMods called ‘Remnants – Secrets of the Enclave’, created by RascalArt.

“Delve into three distinct Enclave-themed dungeons, each filled with unique equipment and new enemy types which you can then release into the Wasteland to encounter again if you wish,” reads the description of the mod.

Sadly, despite the Xbox versions of Fallout 4 supporting mods via the Creation Club, ‘Remnants – Secrets of the Enclave’ is a PC deal only and is not available on consoles.

Fallout 4 is out now on PC, PlayStation and Xbox. It’s also included with an Xbox Game Pass subscription at no extra cost.
