Battlefield 5 is set to include several fresh and exciting new multiplayer game modes, but one marquee feature won’t be arriving on launch day. In a new blog post, developer DICE has indicated that Grand Operations — multi-stage, 64-player engagements — will not arrive on day one.

“Grand Operations is the ultimate multiplayer experience,” DICE said, “designed to seamlessly showcase the maps and modes of Battlefield V. Each Grand Operation presents a powerful narrative experience inspired by historical events. Shortly after launch, you will be able to take part in the first Grand Operation.”
