During Microsoft's E3 2018 briefing, dedicated Gears of War studio The Coalition showed up to debut a trio of new games in the series. Among those was a brief teaser for Gears Tactics, a PC turn-based strategy game.

Tactics takes place 12 years before the first Gears of War. You can customize your own squad to take on threats in what was described as a more aggressive version of the classical tactics formula. And of course, as a Gears game, it will feature larger-than-life boss battles.
