Back in March, there were reports that the new Battlefield game would feature loot boxes in some capacity. As it turns out, that won't be the case. A representative for Battlefield V publisher Electronic Arts told Kotaku, "I can confirm that there are no loot boxes."

The rumor was that Battlefield V's loot boxes would contain only cosmetic items, but the statement makes it sound like there will be no loot boxes whatsoever. The last big Battlefield game, 2016's Battlefield 1, featured loot boxes, as a lot of games today do.
