After 24-hours of Bobble Heads, Please Stand By, and the occasional appearance of a human being, the Bethesda stream finally turned into an actual announcement. The big news is that a new Fallout game is most definitely coming with Fallout 76, but speculations are swirling around the internet of just what the game will be. However, there are lots of clues that say that Fallout 76 is going to be all about the multiplayer.

The biggest indicator that Fallout 76 won’t be a part of the traditional single-player experience is in the name. According to Fallout 3 and Fallout 4 lore, vault 76 was a control vault – meaning they didn’t just flood it with poison or drugs or something else weird. It was a vault designed to open just 20 years after the war with the purpose of recolonizing the planet. It will also predate (if it does open just 20 years after the war) every Fallout game thus far, meaning players might be in a far distant land so as not to conflict with previous titles’ lore.

We also know that Bethesda has been playing around with the idea of online play for a very long time. Before Fallout 4 was officially confirmed, rumors buzzed that it would be an MMO. Bethesda already ventured into online gaming with Elder Scrolls Online. This was a less than stellar entry into the MMO market, but the game still did moderately well (and continues to do so). More importantly, Fallout 4 was laying the groundwork for something that will more than likely be far more lucrative to Bethesda, which is an online game more in the vein of survival and building.

Fallout 4 was clearly pushing one concept very solidly – building. Despite previous titles focuses on guns and grit, Fallout 4 wanted players to build sim-style so the wasteland would have some place to live and survive. Unfortunately, Fortnite did a far better job with the builder model. Building in Fallout 4 was too complicated, and uneven terrain, clipping, and immovable objects made the process cumbersome and unwieldy. There are, however, simple fixes that would make the process vastly easier, fixes Fortnite has incorporated already. Building a wall and then simply editing that wall for a window or door is how Fallout 4 should have handled the system. Instead, it was laborious and frustrating.

But Fortnite proved the success of builders, and Bethesda has all the assets available to take building to the next level. The biggest difference between Fortnite and other Battle Royales is in the building. It completely changes the dynamics of gameplay, and it makes the title wholly unique. It was also born out of the model of H1Z1 (Battle Royale) and the building system of Rust. In a way, Fallout 76 could do all these things better.

Fallout has a history and lore that predates any current survival or Battle Royale game. Zombies have been a part of the survival element of Fallout since Fallout 3, and mods long ago turned the game into a far more survival oriented landscape. So without much effort at all, Fallout 76 already has a building mechanic, an environment (complete with dozens of aesthetics and life forms), and piles and piles of survival elements in which to draw upon.

If the game is about gathering materials to build – well Fallout 4 already did that. The tools are just waiting to be reapplied to a new title. Survival? Radiation sickness, food, dehydration, and ammo conservation have been a part of Fallout for years. And there is also one very clear sign that points to what Fallout 76 will be – the trailer.

The only dialogue in the entire trailer tells the player, “You must rebuild.” In the past, Fallout trailers have featured deathclaws, power armor, Fat Boys, and robots. Fallout 76, though, features one thing – an empty vault. The trailer focuses on other things instead like books, lamps, and decorations – all things that would indicate a focus on building. All signs in the trailer point to mass celebration, but there are no signs of life. The only thing we see is a solitary figure strapping on his pipboy and leaving. The message is pretty clear.

Vault 76’s time has come. The citizens of the vault are being sent into the world for a purpose – to rebuild. More than likely, this is where the game will begin for players, creating a character and leaving the vault to charge into a world full of other players all on a mission to build. The empty commonplace of Vault 76 even displays an enormous banner to celebrate “Reclamation Day”.

If we needed any further indication that this is what is happening, Kotaku reported that sources close to the project have confirmed just that. The sources said the game will feature traditional quests found in nearly all Bethesda projects as well as base building and survival mechanics. Signs also indicate that it will be more like Rust and DayZ than it will Fortnite or PUBG.

If anyone needed more obvious indications that this is Bethesda’s big push into Fallout Online, it is worth remembering that Bethesda has been interested in online play for at least seven years. Originally, Interplay – the creators of the first two Fallout games – had exclusive rights to Fallout Online. However, Bethesda and Interplay entered into a legal dispute about those rights, with Bethesda eventually settling out of court with Interplay. The end result? Bethesda paid out two million dollars, but all creative rights to a Fallout Online world were theirs. Until now, those rights have sat unused.

Just what that online world will look like, and the details of how it will play out, will remain a mystery until Bethesda’s huge E3 event, where we can also expect to see plenty of info on Rust 2.
