Sledgehammer Games and Raven Software have dropped a brand-new SMG for use in Vanguard and Warzone in Season 3 Reloaded.

As teased lore-wise in the initial Season 3 Roadmap, "little is known" about the H4 Blixen/Carl Gustaf M/45 SMG "except that it seems to use a 9x19 mm cartridge and shares some design techniques with the Sten and PPSh-41." For those looking to get their hands on the new weapon as soon as possible, here's a breakdown of how to unlock the H4 Blixen/Carl Gustaf M/45 SMG in Call of Duty: Warzone and Vanguard.

Note: At the time of publication, the H4 Blixen is named the "Carl Gustaf M/45" only in Warzone.

Warzone and Vanguard H4 Blixen (Carl Gustaf M/45) SMG Unlock Methods

Players have two options to acquire the Season 3 Reloaded H4 Blixen SMG.

The first and most straightforward way is by simply purchasing the new Job Weld Done bundle (1,200 CP), which includes the "Space Industry" blueprint for the H4 Blixen, an emblem, a sticker, a charm, a calling card and one battle pass tier skip.

The other is by completing one of its unlock challenges:

  • Vanguard Multiplayer/Warzone: Get 3 slide kills in a single match 15 times.
  • Vanguard Zombies: Use SMGs to eliminate 50 Zaballas.

For those looking to complete the challenge in Vanguard Multiplayer or Warzone, keep in mind that if you ADS while sliding and shooting, it stops the slide and makes the kill not count. You need to be hip-firing for you to maintain the slide.

As mentioned by Warzone content creator Metaphor on Twitter, perhaps the easiest way to get this done is actually by playing Modern Warfare (2019) Hardcore Shoot the Ship as it allows you to get the slide kills and leave the matches early.

In Vanguard Zombies, Zaballa the Deceiver is a special enemy type that spawns on the Terra Maledicta map starting on round six. She's a bit harder to kill than the normal zombie, but it's a relatively simple process as you'll want to focus your fire on her three masks as weak points.

As usual, once you’ve cleared at least one of the required challenges, the H4 Blixen/Carl Gustaf M/45 will be accessible for free across both games.
