Epic Games' Fortnite is a survival game in which you build bases, craft items, and generally try to survive as monsters destroy what you've built, and it's about to enter early access for players to give all this a go.
This is exactly what we're doing, then, today on GR Live, as we'll be playing two hours from 15:00 BST on our live page to see what the game is all about, and whether we have what it takes to survive.
