A tweet from the Battlefield reveals that a free trial weekend for Battlefield V kicks off tomorrow on Origin. This will be the first of three such samples of the military shooter they have planned for this month. Here's a FAQ with all the details, and here's an overview:

OCT 10 – OCT 13
Weekend 1: Rush
The first weekend lets you try out Rush, the intense game mode where you never have a moment to waste. Attack or defend the objectives and always keep an ear out for artillery strikes when this mode is available for a limited time. Enjoy Rush on Operation Underground, Rotterdam, Narvik, Mercury, and other maps – and complete the Weekly Challenge to unlock the Captain Hadlow vehicle skin for the Stug IV.

OCT 17 – OCT 20
Weekend 2: Infantry-Focused Conquest
Engaging in the flag-capping rumbles of Conquest is the most classic way to experience Battlefield’s all-out war. You’ll be able to try the mode on the infantry-focused maps Operation Underground, Rotterdam, Devastation, Marita, and Arras. Complete tasks to earn a coveted weekly reward: the Trench Carbine.

OCT 24 – OCT 27
Weekend 3: Grand Operations
Take on a high-flying experience with Airborne, kicking off the multi-mode Grand Operations. Spearhead an upcoming invasion on the maps Twisted Steel, Narvik, Hamada, Rotterdam, and Panzerstorm. This weekend comes with a very special challenge for all of the community. Complete it together and earn the anti-aircraft Fliegerfaust gadget.
