Avengers: Endgame finally hits theaters tonight, and Fortnite is getting in on the fun with a new Endgame event. Of course, this isn’t our first Fortnite/Marvel mashup, as Thanos has already appeared in the game, but this crossover is more extensive than the first one. This time around, players get a new limited-time mode, in which they have to race to collect the Infinity Stones before Thanos, can earn a variety of Avengers goodies, including the iconic Quinjet, and purchase a couple Avengers outfits – the first is Black Widow, the second will be revealed next week.
