In addition, Microsoft also announced that they have acquired a number of other studios. These studios are Undead Labs (State of Decay), Playground Games (Forza), Ninja Theory (Hellblade), and Compulsion Games (We Happy Few).
If you already thought that Undead Labs and Playground Games were already owned by Microsoft, you wouldn't be alone. The real surprises here are the acquisitions of Ninja Theory, the studio behind Hellblade: Senua's Sacrifice, and Compulsion Games, the studio behind the upcoming We Happy Few.
