In case you forgot, Master Chief is available to play in Rainbow Six Siege

For many, Rainbow Six Siege's latest crossover is the perfect blend of nostalgia and contemporary gaming, a testament to the timelessness of characters like Master Chief.

But, one can't help but wonder, why now? It's no secret that both Rainbow Six Siege and Halo: Infinite experienced their fair share of challenges. Be it the attrition on Steam charts or a few rough patches in their esports scenes, it hasn't been an easy ride. But both games have been showing signs of resurgence. Siege's player count in this year paints a positive picture, and Halo Infinite seems to be regaining its footing.

A collaboration of this magnitude could very well be the adrenaline shot both franchises needed. But then again, maybe it's just the result of two gaming giants recognizing the potential goldmine of merging their devoted fan bases.

With the increasing popularity of crossovers in live service games, like the amalgamations we've seen in Fortnite, this is an expected move. Gaming universes are blending more frequently, creating a landscape where Spider-Man can duke it out with Batman or John Wick. Still, it's hard to overstate the magnitude of this particular blend. Master Chief isn't just any character; he's a symbol, a legend in the realm of gaming.

Now, for those pondering the future, it's uncertain whether Ubisoft plans further integrations with non-Ubisoft projects. But given Master Chief's appearances in other games, like Fortnite, it does seem like the doors of collaboration are wide open.

XDefiant, in particular, seems primed for such ventures, but that will likely only come after the supposed Call of Duty rival hits the market.

In an industry where changes come at the drop of a hat, Rainbow Six Siege's commitment to evolving and expanding its horizons stands out. It's a game that's nearing a decade but shows no signs of slowing down, as evident from its latest roadmap and recent updates like "Operation Heavy Mettle".

With the inclusion of Master Chief, Ubisoft is sending a clear message: in Siege, the only limit is imagination.

However, amidst all this excitement, let's not forget the very essence of both these games. Rainbow Six Siege and Halo are not just about characters or skins. They're experiences, each holding a unique space in the hearts of gamers. As the long-time protagonist of Halo (or, at least his armor) storms the tactical battlegrounds of Siege, one can't help but think: in the vast universe of gaming, isn't it wonderful when worlds collide?
