Hey, remember how 343 made a real-life Breakout arena (opens in new tab) from Halo 5: Guardians (opens in new tab)? Well now there's a video of the game's spokespeople playing a round against a bunch of celebrities. No matter what Frank O'Connor says about being able to use a foam-dart firing Magnum best because he likes it in the games, it looks quite a bit different to the action we're used to.
Grenades are replaced by bouncy balls, it's very much a cover shooter, and everyone looks like they're wearing the armour from that episode of The X-Files where they're inside a video game (opens in new tab).
That's not to say there aren't similarities: everyone Hail Maries grenades at the start, there are shoutcasters struggling to keep up with events, and the chaps from Workaholics (you should watch Workaholics (opens in new tab)) quickly realise that teabagging is allowed.
