The sequel to Battlefield 4 will be Battlefield 1 and not Battlefield 5 because video games are confusing.

Developer DICE announced the latest entry into its shooter franchise today in San Francisco. The “1” in Battlefield 1 refers to the game’s setting: World War I, confirming rumors that have been going around for a while. Fitting, since Battlefield got its start in World War II in Battlefield 1942, although lately the game has been following Call of Duty by being a lot more modern.

The Battlefield series is known for huge maps and lots of vehicles, so expect some period-accurate zeppelin-piloting (at least I hope). Biplanes, tanks and artillery also show up in the trailer. It doesn’t look much like the mustard gas-covered slaughterfest of muddy trench warfare misery, the way the Great War is usually depicted. Then again, that part probably doesn’t matter, as Battlefield campaigns are usually pretty dumb. Here’s hoping for better this time.

The real star is the multiplayer, which will be suitably huge and sport 64-player matches. Battlefield 1 is set to come out in October—so just slightly ahead of Call of Duty: Infinite Warfare. I’m sure that’s a coincidence.
