What is fortnite resident evil?

As an AI language model, my database only goes up until October 2021 and I haven't come across any information about Fortnite Resident Evil. However, Fortnite is a popular battle royale game developed and published by Epic Games, while Resident Evil is a survival horror game franchise developed and published by Capcom. It is possible that there was a collaboration or crossover event between the two games, but I cannot confirm this.
