Rapper and pop megastar Post Malone was joined by Treyarch design director and YouTubers LEGIQN and CouRage for same Call of Duty: Black Ops 4 multiplayer and Blackout action, and the musician was in a trolling mood.
With Black Ops 4 launching globally on October 12, Activision has been acutely aware of the importance of streaming and YouTube as promotion, drafting in big name streamers like Shroud and Ninja.
But, Post Malone is also an avid gamer, and even has his own Twitch channel where he has previously streamed CoD: WWII and PlayerUnknown Battlegrounds. He previously featured in Black Ops 4's CODNATION campaign too.
So, it was no surprise when Call of Duty drafted him in for a sponsored stream, playing alongside with Vonderhaar, but Malone isn't exactly a 'safe' personality, who doesn't hold back from saying how he really feels.
He also isn't the typical celebrity gamer who struggles to keep up with the more dedicated players, showing he clearly does play his fair share of games.
But, when he received the message prompt following a multiplayer match asking him if he enjoyed the previous game, Malone made sure that Vonderhaar saw him press "no".
When playing some Blackout, Post Malone also pointed how ridiculously fast his character would run out breath when swimming underwater - "I can hold my breath in real life longer than that."
To which David Vonderhaar jokingly replied "God damn video game designers!"
And the 'Rockstar' singer and rapper also had some highlight plays, and wasn't holding back in telling the opponents exactly how I felt. We're sure the live stream was marked for mature audiences only though.
With the new Blackout mode directly competing with PUBG (Malone's game of choice), fans may be in for some Blackout streams on his own personal channel, with his album release in 2018 well behind him.
