Epic Games has been teasing a Fortnite crossover with Avengers: Endgame all this week, and the day has finally arrived. The event has been fully detailed in the latest patch notes for the uber-popular battle royale game, which you can read here.

A new mode called Endgame has been introduced for a limited time. This pits two teams against each other, fighting over the six Infinity Stones. Thanos and his Chitauri army make up one team, whose job it is to seize the stones to make the big baddy even more powerful. The Hero team is tasked with preventing this from happening by defeating the enemies, including Thanos. In order to help achieve this, various weapons wielded by the film's protagonists can be found, such as Captain America's shield, or Thor's hammer.

You can get a rough idea of what to expect from the above trailer. What do you think of this cross-promotion between Fortnite and Avengers: Endgame? Snap your fingers in the comments below.
