Helldivers 2 is pulling gear straight out of the grim darkness of the far future. The Warhammer 40,000 Castellan’s Creed Legendary Warbond drops a set of Imperial Guard-inspired weapons, two armor sets, cosmetics, and vehicle patterns into Arrowhead’s co-op shooter, all themed around the Cadian Kasrkin.

Warbond trailer
Arrowhead’s reveal trailer shows the weapons, armor, and vehicle patterns in action ahead of launch.
Weapons and stratagems
Four pieces of firepower headline the Warbond, spread across the primary, sidearm, stratagem, and throwable slots. Each is a direct nod to 40K’s Imperial Guard arsenal, reworked to fit Super Earth’s naming conventions.
| Weapon | Slot | Role |
|---|---|---|
| R/40-K Hot-Shot Marksman Rifle | Primary | Precision rifle, effective at close and long range |
| P/40-K Bolt Pistol | Sidearm | Versatile pistol with heavy stopping power |
| 40-K Meltagun | Stratagem | Short-range superheated beam for melting armor |
| G/40-K Meltamine | Throwable | Proximity-activated burst mine, dangerous to allies too |
Note: The Meltagun comes in as a stratagem rather than a support weapon you carry from the loadout screen, so it occupies one of your four stratagem slots. The Meltamine is a mine, so place it with care since it detonates on anything that trips it.
Armor sets and passive
Two armor sets ship with the Warbond, one medium and one heavy. Both share the same passive, so you pick based on the armor rating and look you want rather than a trade-off in perks.
| Armor | Class | Passive |
|---|---|---|
| TG-8 Sharpshooter | Medium | True Grit |
| TG-122 Demo-Trooper | Heavy | True Grit |
The True Grit passive gives +20 Weapon Handling and +30% Reload Speed for Support Weapons. That combination favors loadouts built around heavy support weapons, where faster reloads and steadier handling matter most.
Cosmetics, titles, and vehicle patterns
Beyond gear, the Warbond adds capes, a player title, and a pattern you can apply to mechs and vehicles for an Imperial Guard color scheme.
- Cape / Player Card: Camo Cloak
- Cape / Player Card: City Fighter’s Resolve
- Title: Still Standing
- Pattern: Castellan’s Green (for vehicles and war machines)
The Kasrkin theme, not Space Marines
The set draws from the Astra Militarum, specifically the Cadian Kasrkin shock troops, rather than the towering Space Marines. That fits the scale of a Helldiver, and it keeps the gritty foot-soldier aesthetic intact instead of oversized power armor.
The in-game framing ties it to Super Earth’s own history. The gear is presented as a recreation honoring Helldivers who made a last stand defending the world of Chara during the First Galactic War, complete with the “TG-8 Sharpshooter” and “T-122 Demo-Trooper” soldier skins.
How to unlock it and confirm you own it
As a Legendary Warbond, this pack is bought once with Super Credits and then stays in your account permanently. You spend Medals to unlock the individual pages of weapons, armor, and cosmetics after purchasing access.
You will know the purchase worked when the Castellan’s Creed Warbond appears as an owned page in the Warbonds menu, letting you spend Medals on its items. Because nothing expires, you can leave items locked and return to finish the pages whenever you have the Medals. If you plan to grab it on day one, saving Super Credits ahead of August 12 is the practical move.
