The second official custom game mode for Battlefield 1 went live over the weekend, let's take a look at how it works.
The mode wasn't live at the time, but it did appear over the weekend. Line of Sight is a variant of Rush, available for a limited time only on the Suez Canal map. The custom mode disables all vehicles, and only allows the Medic and Scout classes. Furthermore, Scouts are even more lethal thanks to increased damage, and the fact your have no grenades.
If you want to get an idea of how Line of Sight is played, check out the video above from Westie. He plays a full round on attack and defence, and goes over a few of the mode's quirks that may not be immediately clear.
