Fortnite's new cyberpunk-themed "Mega" season is coming on Friday. But if you're playing on the PC, you'll need to have a Windows 10 machine. Epic Games already announced in December that it planned to drop support for older Windows versions. And it looks like the change happens today. If you are on Windows 7 or 8 and want to try out the "Mega" season, Epic recommends using NVIDIA's GeForce Now cloud gaming service.
