The new threat, dubbed the Swarm, has taken the place of the underground monsters from the previous games. It turns out that wiping out the Lambent and the Locust wasn’t enough in Gears of War 3.
In a nine-hour single-player campaign, we find out what the younger Fenix is made of, and why he has a hard time getting along with his father, who grudgingly and grumpily comes out of retirement to help to deal with a new threat. After the last battle with the Lambent in Gears of War 3, only hundreds of thousands of people still live on the entire planet of Sera. The story takes place 25 years after Gears of War 3. The main character of Gears of War 4 is JD Fenix (played by Liam McIntyre), the son of Marcus Fenix, the hero of the first three Gears games. Every once in a while, between the firefights, Gears of War 4 pauses long enough to give you some emotion and meaning.
Microsoft says the theme of the game is “father’s legacy, a son’s fate.” That’s not a bad description.
