In any case, players will be able to watch and partake in the live event in-game.Additionally, players can also tune in to popular Fortnite content creators such as SypherPK and Nick Eh 30 to watch the live event as they will stream it on their respective channels. 3) End-of-season event detailsBased on what leakers have been able to gather thus far, the alien Mothership will begin abducting Corny Complex sometime next week. During the abduction, numerous countermeasure devices known as "Orb" will also be beamed aboard the alien vessel.Floating Corny Complex Chuncks..You can see the different Orbs around the Chuncks!!! pic.twitter.com/cf81lAoiKs— FortTory - Fortnite Leaks & News 🛸 (@FortTory) August 31, 2021In addition to these "Orbs," Slone also plans on using the alien time backpacks against the invaders. It's rather unclear how this would work. However, the working theory at the moment is that after the "Orbs" damage or disable the Mothership, players will use these backpacks to invade the alien vessel.These are the timer backpacks the aliens use in their experiments. Perhaps Slone plans to override them so we can stay on the Mothership and take over it.— FNAssist - News & Leaks (@FN_Assist) September 3, 2021While most of the plot is more or less known, the only variable factor in this equation is the fact that Kevin the Cube can also be seen on Doctor Slone's holographic image, alongside a cryptic pictorial representation of Tilted Towers.A Kevin the Cube / Fragment of it can be seen on the holo-table of Slone's plan.Along with this in the bottom corner of this screen is the Runes which we lines up to match Tilted Towers back in Season 5 pic.twitter.com/HL7RVqFBX8— FNAssist - News & Leaks (@FN_Assist) September 3, 2021With just nine days to go until the Fortnite Season 7 "Operation Skyfire" live event begins, players should be getting more information soon. Suffice to say, the Mothership's shadow won't be hovering over the island much longer.Also Read: Fortnite Chapter 2 Season 8 (2021): Release date, timing, battle pass skins, and more
