August's Top Campaign: McDonald's Side Mission
Fancy a side mission?
Throughout August, McDonald's has been running its second year of "Side Missions", a marketing campaign built around the idea that a trip to Maccies is always a welcome detour from whatever you're actually meant to be doing. This year they've teamed up with Xbox, bringing six major gaming franchises, Halo, Fallout 76, Forza Horizon 6, Overwatch, World of Warcraft and Candy Crush, into a limited-time menu, an in-app rewards system, and a 60-second hero film that had me grinning within about three seconds. This is no accident, it's one of the smartest bits of gaming crossover marketing I've seen all year.
I'll admit, I'm a sucker for a good gimmick, but I'm even more of a sucker for one that actually understands its audience. Side Missions gets that completely.
What makes this ad so special?
McDonald's Side Missions isn't new, it first launched back in 2025, but August 2026 is where it's levelled up properly. This year, Leo UK teamed up with Xbox to bring genuinely legendary in-game food into the real world, off the back of six major gaming franchises.
It's a genuinely clever piece of craft, not just a mash-up of familiar gaming references thrown on screen for the sake of it, but an actual mini-story: everyone, no matter what world they're from, agrees that a Maccies run is worth leaving the main mission for.
And the menu backs it all up. Black Pepper & Garlic McNuggets inspired by Halo's Moa Nuggets, Blamco Cheese Bites lifted straight from Fallout 76. It's the kind of detail that only lands if you actually know your audience, because a casual observer would have no idea what any of that means, but a gamer absolutely does. That's the point.
What this ad teaches us
It taps into how a whole generation already talks about their day
Here's the bit I find genuinely clever. Side Missions isn't just borrowing gaming language, it's borrowing a way of thinking that's already massive online. Scroll TikTok or Reels for five minutes and you'll see it everywhere: people treating their own life like a story, a campaign, a game they're playing. "Main character energy." Daily quests. Side quests. It's become completely normal for someone to caption a video "went on a side mission" when they've wandered off from their mates on a night out, or nipped somewhere they weren't supposed to on the way home.
That's exactly the joke at the centre of this ad, just told through Marines and orcs instead of a group of mates on a night out. Whatever "main mission" you're supposed to be on, a trip to Maccies is the universally accepted, fully sanctioned detour. McDonald's has simply given that feeling a name their audience already uses, and packaged it back to them with a film that's confident enough to be genuinely funny.
Gamifying the mundane makes people show up
The other genius part is the app. Side Missions relaunched in the MyMcDonald's app with a fresh run of daily missions, giving people a reason to open it every single day rather than just when they're hungry. Complete a mission, unlock a deal, or use your points to unlock in-game rewards like skins, emotes and boosters, including a McDonald's-inspired Master Chief armour set for Halo. Small wins, daily habits, the promise of something better if you keep playing. It's the exact reward loop that keeps people glued to actual video games, just wearing a McDonald's uniform.
What we can learn from McDonald's
The biggest lesson here isn't really about gaming at all, it's about listening to how your audience already describes their own lives, and building a campaign around that language rather than trying to invent something new.
McDonald's didn't need to teach anyone what a side mission is. Gen Z already live by the concept, on TikTok, in group chats, in captions under night-out videos. All McDonald's had to do was notice it, then build a menu, an app experience and a genuinely well-crafted piece of film around a phrase people were already using for free.
If you're planning a campaign, ask yourself: what language is your audience already using to describe the thing you're selling? You don't always need a new idea, sometimes you just need to be the brand smart enough to spot the one already sat in front of you, and the craft to do it properly once you have.
