The new Hereford looks fantastic, with the old, bland concrete blocks being scrapped in favour of a WWII aesthetic that gives the map a far more distinct visual style, full of fighter planes, antique cars and crumbling brickwork. The map will still feature plenty of nods to the old Hereford however, something that the developers hope will retain the “soul” of the map, while making it far more visually interesting.

The rework will overhaul more than just the skin of the map. Hereford Base was the first map ever prototyped for Siege, and since then the game has shifted significantly, leaving Hereford behind. Nowadays, it feels clunky and bland to play on, in stark contrast to newer maps like Villa or Theme Park. Compared to the rest of Siege’s maps Hereford is tiny, leaving defenders very few options in terms of objective locations, and it’s far too easy for attackers to lock down the central staircase, preventing rotations and bottling defenders into the site, where they can easily be picked off.
