Halo: Reach Designer Says Modern Warfare Was a 'Huge' Campaign Inspiration
Niles Sankey, a designer on Bungie's final Halo game, says the first two Modern Warfare games heavily shaped Reach's campaign moments and tone. The admission is a fascinating footnote given that Infinity Ward was secretly building a 'Halo Killer' at the same time.
Two Franchises, One Mutual Respect
For much of the mid-2000s, Halo and Call of Duty occupied opposite corners of the console shooter ring. Fans argued endlessly about which series was better. Publishers watched sales charts like hawks. And somewhere in the middle of all that noise, the developers themselves were apparently paying very close attention to each other.
Niles Sankey, a designer on Halo: Reach, revealed on Twitter this week that the first two Modern Warfare games were a “huge” inspiration for the campaign of Bungie’s final Halo title. Sankey was responding to a post about the iconic nuke sequence in Call of Duty 4: Modern Warfare when he opened up about just how much Infinity Ward’s storytelling influenced the team at Bungie.
“Many of the moments in Reach were inspired by the brilliant work of Infinity Ward, including the Nobel team squad interactions, and ‘Objective Survive’ was spiritually inspired by the Nuke sequence [in Call of Duty 4]. We just tried to push it one step further,” Sankey wrote.
He was careful to note that Bungie wasn’t simply playing catch-up. The team felt Halo had clear advantages over Call of Duty in areas like enemy AI and vehicle combat. But Sankey acknowledged that Infinity Ward was winning on other fronts, particularly in tonal execution and dramatic storytelling, and that it made sense to learn from what they were doing right.
The Halo Killer That Never Shipped
The admission carries an extra layer of irony when you consider what Infinity Ward was doing on their end. According to the source, during Call of Duty 4’s development, the studio was quietly prototyping a sci-fi shooter internally nicknamed “HK,” which stood for Halo Killer. The project reportedly featured aliens and advanced technology, and the goal was straightforward: dethrone Halo as the dominant shooter franchise.
That project never shipped. Instead, the Modern Warfare series accomplished the same goal without ever leaving contemporary military settings. Call of Duty’s meteoric rise through 2007 and beyond pulled millions of players away from Halo multiplayer, and the franchise never quite recaptured the cultural stranglehold it had before.
Infinity Ward did eventually revisit the sci-fi concept with Infinite Warfare in 2016, though Sankey’s source notes that it looked nothing like the original HK prototype. That game dropped aliens in favor of human-on-human space warfare and earned considerable praise for its campaign, even if the broader package landed with a thud commercially and critically.
What Reach Got Right
Halo: Reach, released in 2010, was Bungie’s farewell to the series they created, and it remains for many fans the emotional peak of the franchise. The game told a prequel story about a squad of Spartan soldiers fighting a losing battle against the Covenant invasion of the planet Reach. Nobody makes it out. The whole thing is structured as a tragedy from the opening cutscene.
That tonal ambition, it now turns out, drew directly from what Modern Warfare did so memorably. The nuke sequence in Call of Duty 4 is still one of the most discussed moments in shooter history precisely because it puts the player through something genuinely affecting. Sankey and the Reach team were clearly watching.
What makes Sankey’s comments land so well is the lack of defensiveness in them. He isn’t downplaying Bungie’s contributions or overstating Infinity Ward’s. He’s describing something that any honest creative team does: look at who is excelling at the things you want to be better at, and figure out why it works.
It’s worth noting that the co-creator of Halo has recently called publicly for the series to return to that darker, more grounded tone Reach embodied. Whether the current stewards of the franchise are listening is another question entirely. But the blueprint, apparently, has been sitting there for over 15 years.
What did Niles Sankey say about Modern Warfare's influence on Halo: Reach?
Sankey said on Twitter that the first two Modern Warfare games were a 'huge' inspiration for Reach's campaign. He specifically credited Infinity Ward's tonal execution and noted that the 'Objective Survive' mission was spiritually inspired by the nuke sequence in Call of Duty 4, while the Noble Team squad interactions were also shaped by Infinity Ward's work.
Was Infinity Ward ever trying to compete directly with Halo?
Yes. According to the source, during the development of Call of Duty 4, Infinity Ward quietly prototyped a sci-fi shooter internally called 'HK,' short for Halo Killer. The project featured aliens and advanced technology but was never released. Infinity Ward eventually made a sci-fi Call of Duty with Infinite Warfare in 2016, though it was very different from the original concept.
What is Halo: Reach's significance in the Halo series?
Halo: Reach was the last Halo game developed by Bungie. It is widely considered one of the studio's best, featuring a darker, more grounded tone and a tragic story compared to earlier entries in the franchise.
