We officially know when Fortnite Season 6 is starting

Update: Epic has finally put an official date on the beginning of Fortnite Season 6 (and also the end of Fortnite Season 5). The changeover will happen on September 27, giving you less than a week to finish up your seasonal business before all the strange business of this season ends... and the strange business of the new one begins. Thankfully, Epic is also kicking off a 400 percent bonus Match XP weekend to help you clear any last few straggling Battle Pass tiers.

Original story: Not long now and Fortnite season 5 will be a distant memory as Fortnite season 6 spills its secrets. Right now in Fortnite a mysterious purple cube is rolling around the Fortnite map, dropping runes, antigravity fields and zapping anyone that dares defy it. The million dollar question of course is what does it all mean?! Here's everything we know about Fortnite season 6:

When is Fortnite season 6 starting?

Every season in Fortnite runs for 10 weeks, so you should expect to see Fortnite season 6 starting around September 20. That's exactly 10 weeks after the start of Fortnite season 5. However, the in-game countdown is currently pointing to the season ending around the September 24/25 mark. There's also at least one leaker claiming to have found code in-game pointing to a delay from September 25 to October 2.

There's no way of knowing yet whether a delay could happen but challenges and other dates have been moved before at the last minute, so nothing's guaranteed.   

How much does the Fortnite Season 6 Battle Pass cost? 

The Fortnite Season 6 battle pass is probably set to cost the same as it has done the past few seasons, which is 950 V-Bucks. In order to get that, you'll have to spend some real-world money on the smallest V-Bucks bundle, which costs $9.99 / £7.99. 

Interestingly, Epic has now changed the way it does challenges, which makes not buying a battle pass a slightly more attractive proposition (although of course we're all going to get one, right?). Weekly challenges are now split into two sections, free and Battle Pass. The first three challenges of each week are going to be free, but the other four will only be available if you own the Battle Pass. However, the weekly challenge reward is still locked at four, so you'll have to buy the Fortnite battle pass if you want that sweet reward.

What can we expect from Fortnite season 6?

The most obviously Fortnite season 6 teaser at the moment is the giant purple cube slowly rolling around the map zapping people with lightning. As it moves from one point to another it's leaving behind runes that, like the cube, emit a low gravity field.

The most popular theory at the moment is that it's drawing an actual cube on the map, heading to Loot Lake and that's when... something's going to happen. Data mined coordinates point to six runes in total before a final destination: 

One popular theory is that of some sort of mirror universe element being added to the game in Fortnite season 6, giving players the ability to access another dimension where they're invisible and separate to people in the 'real' world as they move about. That's partly from a very nebulous 'rumour' but has been fuelled somewhat by this loading screen: 

Specifically the fact that Bright Bomber's reflection appears to be an 'evil' alter ego, replacing her shirt's unicorn with a dragon and what some claim is a volcano. I only mention that because volcanos have been found in the game's files: 

There's also sounds and files for lava, lava blobs and more, with everyone latching on to the idea that Loot Lake will become volcanic in some way because fire/lava is the opposite of water. 

The idea of corruption is also a theme floating around for Fortnite season 6. Item swaps and things like opening Llamas seemed to be tinged with purple colour and symbols like the Cube runes. It looks like whatever the Cube is going to do, it's already having an effect. 

One effect we've already seen are some map changes. Without warning Tomato Town changed into Tomato Temple. It was preceded by the return of a small, dried out-looking Tomato Head. While many thought it was the original head, affected by its time in the rifts, the temple makes it clear that wherever he went, there was some sort of jungle tribe that worshiped him - the new building has a Inca temple vibe, with Tomato Head proudly atop the structure. 

It suggests we aren't done with the rifts yet, and almost points to some of last season's rumours of castles, Wild West towns and more replacing large junks of the map. 

A less otherworldly change is that the building work at Tilted Towers has been completed and there's a shop there now...

...while Dusty Divot now has a diner and a merch shop, apparently celebrating the meteor impact. 

Whatever Fortnite season 6 gives us we haven't got long to wait and it's likely the pick up the paces the closer we get. In the meantime why not check out some free Fortnite skins and gear if you've got a PS Plus account.
