At the Xbox E3 Conference The Coalition revealed three new Gears of War titles and obviously one of the being Gears of War 5, but the others are two side titles that many did not expect.
Gears Tactics (Windows 10):
Gears Tactics is the first true Gears of War PC experience that fans have been asking for. Developed and partnership with Splash Damage, “Gears Tactics evolves turn-based tactics games combining signature fast-paced brutal action and character-driven storytelling with customizable squads, upgradable weapons, and of course, massive boss battles”.
Gears Pop!
Now, Gears Pop! was something that no one expected and at first it looked like this would be the only thing shown if you were watching the conference live as it was the first one to be revealed over the other two. This title will be coming exclusively to iOS and Android devices in 2019 and its developed in partnership with Mediatonic.
