Warframe’s Mesa Heirloom update brings a hellish gunslinger and a long list of fixes
The Mesa Heirloom Collection is scheduled to launch across all platforms at 11 a.m. ET on July 11, alongside fixes for Celestial Clash, Uranus Proxima, and Sirius & Orion.

Warframe is adding a fiery new look for Mesa with the Mesa Heirloom Collection, which is scheduled to launch on all platforms at 11 a.m. ET on July 11, 2026. Digital Extremes published the accompanying Hotfix 43.0.7 notes with fixes covering Celestial Clash, Sirius & Orion, Uranus Proxima, and several broader progression and stability problems.
The collection includes the Mesa Heirloom Skin, a matching Duster, Signa, Regulators Skin, Color Palette, Sigil, Glyph, and Prex Card. The Duster can also be removed by setting the Auxiliary attachment option to None, giving players a choice between the full outlaw-inspired outfit and Mesa’s base silhouette.

The hotfix also addresses problems that could desynchronize clients during Sirius & Orion’s Celestial Clash, cause players to miss Void Fissure Relic Rewards, or teleport players back to earlier locations. Other fixes cover the Tenet Envoy, the Secondary Son’s weapon restrictions, mission loading, memory-related crashes, and a duplicate Imperator Vandal entry in player Profiles.
Uranus Proxima receives a large group of mission fixes. These include repairs for boss encounters failing to begin, extraction problems, missing waypoints, incorrect fog brightness on low-spec machines, Host Migration issues, and cases where players could become trapped outside fight areas. The update also fixes several quest cinematics involving Sirius & Orion and prevents certain progression stops in The Old Peace and The Glast Gambit.
The previous Warframe 43.0.5 hotfix focused on Steel Path Railjack rewards and MK IV Railjack Turrets. Hotfix 43.0.7 instead puts the spotlight on the Mesa collection and a broad set of bug fixes across newer content.
