Fortnite: A fortnight in my 40s in Battle Royale

I leap from the battle bus and land in the middle of what appears to be a deserted island, carrying only a pickaxe as a weapon. As I start running, I hear the sound of gunshots in the distance. According to developer Epic Games, more than 125 million other players are also in its grip. It's the first time I've properly dedicated myself to a game since Tomb Raider in the 1990s, when I was a 20-something rather than the 40-something I am today. One hundred of us collect weapons, build defences and track each other down until there is only one person left alive.
