One of the most valuable things you can do for the health of an FPS is let people mess with maps and assemble their own servers. Battlefield 6 is checking both of those boxes at launch with Portal, a web tool and SDK that lets people fire up persistent custom games and create new game modes.
There is no more perfect day-one demonstration of what Portal can do than this surprisingly good remake of Call of Duty 4 Shipment by game dev Matavatar, who had a working version of the map up a day before Battlefield 6 was even live (EA released the Portal editor a bit early).
