CoD Vanguard Season 3 Reloaded update patch notes: New Sphere map, Harpy Operator, H4 Blixen SMG
The new Season 3 Reloaded update is bringing a wealth of new content to CoD Vanguard. From the new Sphere map to the long-awaited H4 Blixen SMG, here’s how it all breaks down.
Season 3 has come to the halfway point and, on May 25, the game will once again be going under the knife for some major updates.

This time around we’ve got a new map to lead the charge and a ton of fixes across multiplayer and Zombies, including some substantial improvements to Zaballa the Deceiver as well as a hearty helping of lethal and tactical adjustments.
Let’s take a look at everything coming in the Season 3 Reloaded update…

Season 3 Reloaded update shakes up Vanguard
Sphere is an original map in Vanguard. Tucked underneath an old mining facility, this close-quarters arena will offer a similar gameplay experience to familiar maps like Shipment and Das Haus, although maybe just a touch slower than those madhouses.
This action-packed battlefield joins Mayhem as the two latest additions to Vanguard’s impressively-sized map pool.
This update also brings the H4 Blixen into the fight. This power puncher focuses on mobility and accuracy while on the move, and the challenge to unlock it reflects that.
