Battlefield 1′s closed alpha has been data-mined, revealing the chapters titles of its single-player campaign, character names, weapons, gadgets and more. The information was dumped on Reddit by a user named Lobix, along with an apology to the game’s developer and publisher: “EA & DICE, I’m sorry <3.”

Based on the leak, it looks like the single-player campaign in Battlefield 1 will have seven episodes in total, including a prologue and epilogue. Within these are a number of chapters; in total there are 20 chapters.

Special dog tags will be awarded to players that complete “The Road to Battlefield 1” missions in Battlefield 4 or Battlefield Hardline. These will also be given to those that own a previous Battlefield game, attended a Battlefield 1 event in real life or online. There’s also dog tag awards for those that participated in the closed alpha or open beta for Battlefield 1.

The list also suggests there will be over 30 weapons, ranging from handguns to tankers, boats, “behemoth weapons,” and “cavalry weapons.”

In terms of gadgets, there’s the usuals such as mines, grenades, medic bags, and ammo crates, as well as gas masks, and flare guns, among others.

There’s also a list of maps, melee weapons, game modes, camos, and you can hear exclusive sounds from the game. We won’t post these in any further details to avoid spoilers, but those interested in seeing these can click here.
