Here's a quick description of what's featured in the new trailer:
In this short gameplay demo of Gears of War 4, our heroes JD, Del, Kait and Marcus Fenix are in pursuit of creatures called the Swarm. With their village destroyed and Kait's mom abducted, the squad gives chase through the wilds of Sera and must battle through an incredible storm.
In addition, there's another new video that offers a flyover of Forge, one of the game's upcoming multiplayer maps.
Microsoft will be giving attendees of this week's San Diego Comic-Con a chance to play part of the campaign for Gears of War 4 and the company will also be holding panels on the game at both Comic-Con itself as well as the nearby Nerd HQ event. Gears of War 4 is due for release on October 11.
