Halo: Campaign Evolved is set to instill nostalgia in gamers when it releases on July 28. The original Halo released a massive 25 years ago, and Combat Evolved’s Anniversary Edition was 15 years ago. Now, you’ll be able to take on the classic adventure in a modern setting, complete with new missions, and even new Skulls to hunt down. But will you have to fork out to enjoy it, or is it included on Microsoft’s subscription service?
