Fortnite is changing physics engines to the Unreal Engine’s new Chaos engine. While that won’t mean any big changes for the game, it will mean a delay to the start of Chapter 2 season 2.

Epic Games is changing up Fortnites physics engine. The popular battle royale game will move to the Unreal Engines new Chaos physics engine with the 11.50 update, which is currently scheduled for early February.
While a change in the games physics engine may sound like a big deal, in the announcement of the change, Epic says that the main goal is to make sure that Fortnite still feels like Fortnite. In other words, you shouldnt notice much of a difference. To make things smoother, Epic is also rolling this change out slowly by starting tests with a small group of players.
Because of this new update, Epic has also pushed back the start of Fortnite Chapter 2s second season. This marks the second delay of the current Fortnite season. This season began with the start of Chapter 2 back in October 2019. The season was originally set to end in December, but was extended to Feb. 6. On Friday, Epic pushed the date for Chapter 2 season 2 back to Feb. 20.
As always, this delay doesnt mean that nothing is happening in Fortnite. Along with the extra weeks added to the season, Epic is also adding new Overtime Challenges for players to complete, and a new two-week event that hasnt been announced yet. Epic says that it will tease this event on its social media channels.
Notably, Fortnites Twitter responded to a tweet about Warner Bros. Birds of Prey movie just this morning, saying See you soon HarleyBirds of Prey hits theaters on Feb. 7 so, that seems like a good guess that the upcoming event could be a tie-in to the Harley Quinn-centric movie.
So far, Chapter 2s first season has offered fewer changes than previous seasons at least that Epic has noted publicly but theres no way to know if that will continue into season 2. The announcement post does include a few teases of the changes coming next season, but Epic has redacted them out so we cant see what exactly they say. For now, well just have to wait until Feb. 20 to see what kind of changes Chapter 2 season 2 will bring to Fortnite.
