Rainbow Six Siege is stepping into bold new territory with its latest tease, a crossover with the wild and chaotic world of Borderlands. The popular tactical shooter, now rebranded as Rainbow Six Siege X, dropped a surprise teaser that hints at a major themed event featuring characters, visuals, and animations inspired by Gearbox’s iconic looter shooter franchise. The full reveal is expected on July 15, 2025, but fans are already buzzing with excitement.

The teaser, posted on Ubisoft’s official X account, offered a brief but intriguing look at what’s to come. Viewers were shown a character skin modeled after the Psycho Bandit, Borderlands’ most recognizable figure, along with a stylized gun skin designed with the game’s signature cell shading look. There was also a glimpse of what might be a special MVP animation involving a lighter drop, a nod to Borderlands’ over the top attitude.

While the full scope of the collaboration remains under wraps, the crossover has been a hot topic in online communities since May. During the R6 RE:LO:AD tournament in Rio de Janeiro, sharp eyed fans spotted a Borderlands style mask in a live match stream, igniting speculation. Soon after, leaks began surfacing, suggesting which operators and weapons would receive the crossover treatment.

According to circulating screenshots, operator Mozzie is expected to get the Psycho Bandit outfit, while IQ may take on the appearance of Lilith, the powerful Siren from Borderlands. Their respective weapons, the Commando 9 and the 552 Commando, are also rumored to receive themed skins. Although Ubisoft has yet to officially confirm the leak, the teaser seems to validate at least part of the speculation.

The Borderlands collaboration marks the first franchise crossover since the Siege X update launched, a major overhaul of Rainbow Six Siege that brought with it improved audio, enhanced visuals, and round based bans. Past crossovers have included fan favorite skins like Master Chief for Sledge and Lara Croft for Ash, but this Borderlands event is the first under the game’s updated identity.

The timing of this crossover is especially strategic. Rainbow Six Siege X has several upcoming esports activations lined up, including the ongoing Element Five tournament, the Central Combine for tier two teams, and a high stakes appearance at the Esports World Cup from August 5 to 9. While Ubisoft hasn’t announced whether the Borderlands content will tie directly into these events, the crossover’s arrival just before these tournaments suggests a synchronized rollout designed to maximize visibility and engagement.

Collaborations like this allow Rainbow Six Siege to keep evolving, bringing in elements from outside gaming worlds to freshen up its competitive format. For long time fans and newcomers alike, the fusion of Borderlands’ anarchic style with Siege’s tactical precision could lead to a uniquely entertaining in game experience.

More details about the collaboration, including its scope, featured cosmetics, and launch timeline, are expected during the official reveal on July 15. Until then, fans will be watching closely for any further hints from Ubisoft or additional leaks that offer a deeper look into this crossover.
