McDonald's Turns Xbox Game Food Real in 'Side Missions'
McDonald's has turned fictional in-game foods into real menu items in 'Side Missions', a UK campaign with Xbox created by Leo UK that spans six gaming franchises, TV, social, OOH and the MyMcDonald's app.
When a McNugget Becomes a Side Quest
McDonald's has relaunched its 'Side Missions' platform for 2026 with a headline tie-up with Xbox, created by Leo UK with media handled by OMD. The idea is deceptively simple: take foods that only exist inside games and put them on a real menu.
The line-up draws on six franchises — including Halo, Fallout, Forza Horizon, Overwatch, World of Warcraft and Candy Crush — turning invented items like Halo-inspired nuggets and Fallout's Blamco Cheese Bites into things you can actually order. It runs across TV, social, out-of-home, in-restaurant and the MyMcDonald's app, with exclusive in-game rewards built in.
Why Gaming Culture Is the New Prime-Time
For a mass brand, gaming is no longer a niche channel; it is where a huge slice of the under-35 audience now spends its leisure time. By treating a McDonald's visit as a 'side mission' within that culture, the brand borrows the language and rituals of players rather than shouting at them from the outside.
The clever part is the value exchange. Exclusive in-game rewards give fans a concrete reason to move from the sofa to the app, tying a cultural moment to first-party data and repeat visits. That is the difference between a stunt and a system.
What Smaller Brands Can Take From It
You do not need six gaming licences to apply the thinking. The transferable move is to enter an existing fandom on its own terms — a game, a sport, a subculture — and add something genuinely useful or playful, rather than slapping a logo on it.
Start with one community your customers already belong to, co-create a small reward or experience that only makes sense inside it, and give people a reason to act now. Relevance plus a real incentive beats reach bought cold.
Quick FAQ
What is McDonald's Side Missions campaign?
Side Missions is a McDonald's UK marketing platform, relaunched in 2026 with Xbox, that turns fictional foods from popular video games into real, limited-edition menu items, supported by TV, social, OOH and app rewards.

Why are brands advertising inside gaming?
Gaming reaches large, engaged younger audiences who are hard to find on traditional media. Brands use it to build cultural relevance and drive app engagement through rewards rather than interruptive ads.
Side Missions works because it doesn't treat gamers as a demographic to interrupt — it treats them as an audience to join. When a brand adds real value inside a fandom people already love, it stops being an advertiser and starts being part of the fun. That's the whole game now. — Daniel Nikolla, Founder of Merx Marketing
