The game follows protagonist Marcus Fenix, a soldier in the Coalition of Ordered Governments tasked to lead a last-ditch effort to destroy the Locust Horde and save humanity.

All six installments in Gears of War featured several multiplayer modes that allowed players to compete against each other or team-up to battle AI opponents on Xbox Live.

A contingent of COG commandos, led by Marcus Fenix, Dominic Santiago, and Victor Hoffman launch a daring raid on a UIR stronghold to steal the schematics for the Hammer of Dawn.

Six weeks after the COG and UIR agreed to an armistice, a race of subterranean creatures known as the Locust Horde emerge from Sera's depths and begin assaulting human cities, wiping out 25% of the world population in the first 26 hours, referred to as 'Emergence Day'.

Marcus is reinstated into the COG army to supplement their depleted ranks and joins Dominic Santiago in Delta Squad on a mission to map the Locust tunnel network in preparation for the bombing.

In the months following the Lightmass Offensive, the human population begins to suffer from a respiratory condition known as Rustlung, caused by the inhalation of Imulsion evaporated by the bombings.

After killing the Riftworm, Delta is ordered to locate the Locust stronghold by accessing intel from New Hope, a decommissioned COG research facility.

Acting on advice from Adam Fenix, Queen Myrrah intends to sink Jacinto and use the surrounding seawater to flood the Hollow, drowning the Lambent and denying the humans their last safe city.

Due to the Hollow being flooded, the Imulsion has begun to pollute the surface - causing a pandemic that aims to turn all life into Lambent organisms.

After the helicopter crash, Adam was rescued and brought to a secret island facility called Azura where he has been working the past seven years on the Imulsion countermeasure, a targeted radiation weapon which will neutralize both the Lambent and Locust.

With military cadet Sofia Hendrick and former UIR soldier Garron Paduk in Kilo Squad, they disobey orders and deploy the Lightmass Missile to the destroy Locust forces occupying Halvo Bay.

A separate campaign, Aftermath, features Baird, Cole, and Paduk in the hours before the activation of the Imulsion countermeasure in Gears of War 3 as they prepare for reinforcements in the upcoming battle of Azura.

Following the end of the Locust War, the humans of Sera reform the COG, led by First Minister Anya Stroud, wife of Marcus Fenix.

After joining the military, both JD and Delmont "Del" Walker are forced to execute civilians during a protest in Settlement 2, prompting them to leave the COG and becoming Outsiders.

Kait learns the Locust were the result of genetic experiments on human children sick with Rustlung and mutated with the DNA of creatures from the Hollow.

Gabriel Diaz, Kait's father and Oscar's brother, and Major Sid Redburn are tasked with assassinating Locust scientist, Ukkon, who is physically immortal by regenerating any damage done to him.

Modes include "Warzone" and "Execution", both similar to a typical deathmatch, and "Annex" and "King of the Hill" where teams have to control a marked zone on the map.

[31] General RAAM was announced as a playable character in Killer Instinct: Season Three during Microsoft's E3 2016 press conference on June 13, 2016, and was released following the presentation's conclusion.

As he was unaware that the Locust council is listening in, RAAM decides to include High Priest Vrol and Karn in his plot to convince Queen Myrrah to invade the surface.

RAAM manages to get Karn to help by playing on his doubts and they purposefully allowed the Lambent to reach the Inner Hollow where they attacked the Locust temple.

RAAM presents his plan to win the war by invading the surface, taking it over and flooding the Hollow with seawater in order to wipe the Lambent out once they are gone.

The comic focuses on Team Scorpio—Corporal Jeremiah Keegan, Lieutenant Lahni Kaliso and Outsider Leslie "Mac" Macallister—as they work with Colonel Victor Hoffman, Doctor Hana Cole and King Raven pilot Tak to destroy Swarm Hives across Sera.

Scorpio is able to plant their new Venom Bombs, but accidentally awaken the Hive in the process and have to fight off thousands of overwhelming Swarm forces as the deadly gas spreads.

Hoffman rewards Lahni with a pardon for the crime that had sent her to prison and an official reinstatement into the COG and sets up a meeting for Keegan with his old commanding officer who survived the Locust War.

Mac eventually manages to kill the Warden by ramming it with a truck and then stabbing it through the eye and Scorpio escapes the bunker as the Hive is destroyed.

Mac decides to dedicate himself to continuing the mission of destroying Swarm Hives as it allows him to see Dillon again while he is podded and Lahni and Keegan agree to join him.

In March 2007, New Line Cinema had purchased the rights to make a Gears of War film, with Stuart Beattie writing the script along with Marty Bowen and Wyck Godfrey, who would be producing it.

[53] Producer Wyck Godfrey said of the film adaptation: "I'm not a gamer, but what blew me away about Gears was how it captures the mythology of a war mission and how high the stakes are.

[58] Wyck Godfrey said in December 2009 that the intention of the Gears of War film was "to tell the epic story of an alien planet that's living in a horrific environment just feels like the wrong mood right now".

[60] In April 2013, Variety reported that "Creative Artists Agency is eager to meet with producers in the coming weeks and set up the project elsewhere" and that Stuart Beattie would write the film.
