At the end of its Gamescom 2015 keynote, Microsoft had a big surprise: Halo Wars 2, the sequel to the strategy spin-off, is launching next fall. The game will be exclusive to the Xbox One and Windows 10, and it's being developed by renowned strategy game studio The Creative Assembly (it's also the same studio behind the excellent horror game Alien Isolation). Like the original Halo Wars, which launched on the Xbox 360 in 2009, the sequel is a real-time strategy game, offering significantly different gameplay from the main series.
We don't have much else in the way of details, but you can check out the debut trailer above to get an idea of the story and setting. Halo Wars 2 is part of a big push from Microsoft to turn Halo into an even bigger blockbuster; earlier this year saw the release of a live action series from Ridley Scott, while the much anticipated Halo 5: Guardians will be launching in October, alongside a slick new Xbox One and a new e-sports tournament.
