Microsoft has release over 20 minutes of raw gameplay of Gears of War 4’s first mission, acting as Prologue to the rest of the game.

It catches player up on the current events taking place in the story, as well as some of the game’s history and setting. It also helps get players familiarized with movement, combat, and other mechanics in the game.

You can catch the gameplay above, but, be warned, you might find it a tad spoiler-ish.

Gears of War 4 is set to release on October 11 for PC and Xbox One.
