The Fortnite x Avengers: Endgame crossover has been officially unveiled following the release of a brief teaser poster earlier this week. As a follow-up to last year's Avengers: Infinity War with a playable Thanos, the Mad Titan is back, this time backed by a team of Chitauri warriors and opposed by a team of heroes wielding Avengers weapons.

Unlike last year's theme with one player as Thanos facing against everyone else, the Fortnite Engame crossover spotlights teams battling it out over acquiring the Infinity Stones. The hero team attempts to eliminate the Chitauri forces and defeating Thanos, while the villain team is tasked with recovering all six Infinity Stones that are scattered across the map.

According to Fortnite, the patch notes for this update reveals that each time an Infinity Stone is acquired, Thanos' abilities grow powerful and the Chitauri gain health.

Reality Stone (Red) = Heath & Shields doubled (1000->2000) Soul Stone (Orange) = Siphon activated (grants Thanos shields only) Mind Stone (Yellow) = Jump height doubled Space Stone (Blue) = Ground Pound AOE size tripled, damage x6 Time Stone (Green) = Big knockback added to each hit, damage x3 Power Stone (Purple) = Laser damage x6

Additionally, players can complete challenges to unlock free Avengers-themed rewards like banners, sprays and the Avengers Quinjet Glider. Furthermore, there are new costumes to acquire, such as Black Widow's signature outfit.
