Fortnite's upcoming Chapter 7 Season 4, subtitled "Override," is set to launch on Thursday, August 20, following scheduled downtime. The season will prominently feature hacking and gaming as its core themes, introducing a host of collaborations with well-known video game franchises. An "Unstable" in-game event is expected to provide further context for these developments.

Confirmed collaborations include Sonic the Hedgehog, Persona, Tetris, and Pac-Man. Teasers have already appeared within the game and on official social media channels, with Sonic and Tails spotted alongside Fortnite mascot Peely on the Battle Royale map, and Tetris-shaped clouds visible in the background. Faint Pac-Man music was also reportedly heard in the game.

These franchises, along with others, were featured on decrypted posters found within the files of the "Unstable" event. Mega Man is also anticipated to be part of the "Gaming Legends" season, though not yet officially confirmed. Additional teasers have hinted at the presence of Joker from Persona 5 and a deer character from the Roblox game "99 Nights in the Forest."

Several of these confirmed franchises have associated slogans that tie into "Lobby Hacks," a new mechanic that will allow players to apply perks by entering codes while in the lobby.

Rumors suggest further collaborations are possible, with hints pointing towards the Undertale universe. A tweet from the owner of the company managing Undertale's soundtrack to Tim Sweeney has fueled speculation about Deltarune music potentially being added to Fortnite, possibly as Jam Tracks even if no cosmetic items materialize. Fans have also observed what appears to be a crate from Crash Bandicoot in promotional art for the "Unstable" story event, adding to speculation about that franchise's potential inclusion.

Other rumored franchises making their way to Fortnite include Kingdom Hearts.

The Chapter 7 Season 4 reveal trailer is scheduled to premiere on YouTube on Sunday, August 16, at 12 p.m. EDT, with a reported duration of 1 minute and 39 seconds. Players can anticipate themed Mythic weapons and items inspired by the mechanics of the featured games. Epic Games has indicated that the season will present a "massive video game multiverse," aiming to attract players of all ages. New Sprites to collect are also part of the upcoming content.
