Battlefield 1 publisher Electronic Arts offered a few tidbits of information about the game’s four upcoming expansion packs today, giving players an idea of what they can expect over the coming months.

The first one, They Shall Not Pass, is coming out sometime in March; EA has yet to announce a concrete release date. As with all Battlefield 1 expansions, it will be available exclusively for Battlefield Premium members for two weeks before being opened up to everyone else.

They Shall Not Pass will allow players to step into the boots of the French Army in Battlefield 1’s multiplayer component. The add-on includes four new maps — Verdun Heights, Fort de Vaux, Soissons and Rupture — as well as a new mode, Frontlines, that developer EA DICE describes as “a mix of Conquest and Rush.” They Shall Not Pass also features vehicles such as a new behemoth, the Char 2C tank, and a new elite class in the Trench Raider.

The other three planned expansions for Battlefield 1 are called In the Name of the Tsar, Turning Tides and Apocalypse. EA did not give any release windows for those add-ons, but did provide the following blurbs:

Battlefield 1: In the Name of the Tsar Enter the biggest front of WW1 with the Russian Army. Ride in Galicia with the legendary Hussars during the Brusilov offensive. Partake in the skirmishes of the Albion assault in a freezing archipelago and fight in the snow covered ravines of the treacherous Lupkow Pass. Battlefield 1: Turning Tides Participate in the amphibious warfare of WW1. Embark with the new destroyer into intense tactical naval clashes. Master the coastal class airship in the fierce interplay between land, air and sea. Engage in the daredevil Zeebrugge raid and storm the beaches in the first days of the Gallipoli offensive. Battlefield 1: Apocalypse Go over the top in the most infamous battles of WW1. Conquer bitterly contested ground with brutal tools and unique weapons born out of desperation and deadlock. Never before have the nightmarish horrors of the Great War been closer as you descend into hell. Prepare to enter the Apocalypse.

EA is offering trials of Battlefield 1 — both single-player and multiplayer — on Windows PC and Xbox One this weekend, from March 3-5. Xbox One players will be able to try out the full game with “unlimited play time,” said EA. Origin users on PC will have access to a small portion of the game that’s similar to what EA offered as the Play First Trial on EA Access and Origin Access: 10 hours of play time with all multiplayer modes on two maps, and the first two War Stories of the campaign.

People looking to buy Battlefield 1 can get the game at a discount during the ongoing EA sale, which drops the price by as much as 60 percent depending on the edition. The base game is discounted by 50 percent to $29.99 on PC, PS4 and Xbox One. For more on Battlefield 1, read our review.
