Gears of War 2 is a 2008 third-person shooter video game developed by Epic Games and published by Microsoft Game Studios for the Xbox 360. It is the second installment of the Gears of War series, with lead design by Cliff Bleszinski. The game was released in North America, Europe and Australia on November 7, 2008, and was released in Japan on July 30, 2009. The game expands technically on the previous game by using a modified Unreal Engine 3. The development team brought in comic book writer Joshua Ortega to help write the plot for the game.

In Gears of War 2, the COG continues its fight against the Locust, who are attempting to sink all of the cities on the planet Sera. Sergeant Marcus Fenix leads Delta Squad into the depths of the planet to try to stop the Locust during the assault upon Locust territory. The player controls Fenix in the main mission campaign, with the ability to play cooperatively with a second player controlling Fenix's best friend and fellow Squad member Dominic "Dom" Santiago. The game includes several existing and new multiplayer modes including five-on-five battles between human and Locust forces, and a "Horde" mode that challenges up to five players against waves of Locust forces with ever-increasing strength. New weapons and gameplay mechanics such as "chainsaw duels" and the ability to use downed foes as "meatshields" were added to the game.

On its release weekend, Gears of War 2 sold over two million copies, and within two months of release, had sold four million copies. It was the seventh best selling video game of 2009 and received several accolades. The game received similar praise as its predecessor, with the new gameplay and multiplayer modes seen as outstanding additions. Gears of War 2, along with its predecessor, are considered to be amongst the best games ever made. It was followed by Gears of War 3 in 2011.

Gameplay

Gears of War 2 is a third-person shooter with an emphasis on the tactical use of cover, and retains much of the same gameplay from the first game. The player, playing as either Marcus or Dominic in the campaign mode, or as any of the human or Locust characters in multiplayer mode, can only carry a pistol, one type of grenade, and two other weapons at any time, though they may swap these for weapons found in strategic locations or left by downed foes or fallen allies. Each weapon can be used for normal fire as well as for melee attacks; the game's signature Lancer Assault Rifle can be used to instantly kill foes in melee with its mounted chainsaw bayonet. The game introduces the ability to engage in chainsaw duels should the player attempt to chainsaw an opponent also using the Lancer; the player is presented with a controller button to press rapidly to try to win the duel and avoid death. Gears of War 2 rebalances the power of the existing weapons while introducing five new ones: a flamethrower, a chain gun, a mortar cannon, a "Gorgon" Pistol, and the Ink Grenade. The chain gun and the mortar are heavy weapons, forcing the player to move at walking speed while carrying it in both hands. The Gorgon Pistol is an SMG-like machine pistol that fires four four-shot bursts per magazine. The Ink Grenade doesn't damage with its detonation, but instead temporarily poisons the area it was thrown, making it very useful for driving enemies out of cover. Grenades can be planted on walls or floors as proximity traps that go off when an enemy nears, but only fragmentation grenades have the ability to kill foes when they go off.

The player's health is represented by a red "Crimson Omen" that fades onto the screen the more damage the player takes; staying out of the line of fire allows the player to recover their health. Depending on the game mode or difficulty, if the player takes too much damage, they enter a downed state where they can crawl around the map to get out of battle and seek help. During this time, a teammate can revive him, an enemy may brutally execute the downed player, or the player may bleed out if too much time has passed. The player can also grab a downed character and use them as a meatshield, allowing the body to absorb damage but forcing the player to use a one-handed pistol. Explosive weapons will simply destroy the character they strike. Like its predecessor, Gears of War 2 features an optional mature content filter, which, when active, makes blood appear as sparks and removes harsh language from the dialogue. Furthermore, progress towards most of the Xbox achievements for the game can be earned in either campaign or multiplayer modes.

Campaign mode The campaign mode in Gears of War 2 allows for a single player or two players playing cooperatively as Marcus or Dom. A new "Normal" difficulty was added between the game's "Casual" and "Hardcore" difficulties. There is also an 'Insane' difficulty that is unlocked after the player completes the game at least once. Players in co-op mode can select different difficulties, and a "communal combat system" will adjust the game's artificial intelligence to give both players a fair challenge. The co-op campaign can be played in a drop in/drop out manner, with the second player able to join the first player's game in progress. As well as collecting some COG tags as in the first game, players can search other story-based items such as personal letters and medical records, with discovered items being added to a war journal.

The campaign features a deeper story with new characters, new weapons, and new enemies according to John DiMaggio, the voice actor for Marcus Fenix. New vehicles have been added to the game, such as the Centaur Tank, which lead designer Cliff Bleszinski describes as a "tank with monster truck wheels." Players will also ride a Brumak and Reavers in the game. Cut-scenes use the better facial rendering technology of Epic's Unreal engine, and engage in more dramatic angles for the conversation, as well as using a video screen on Jack (the all-purpose robot used by Delta squad) to talk with their commanders face-to-face.

Multiplayer Gears of War 2 features an upgraded multiplayer mode that allows up to ten users to simultaneously play in teams of five-on-five. Gears of War 2 includes most of the multiplayer modes, including Execution, Warzone, Annex and King of the Hill, and adds in three new modes. Guardian is a modified version of Assassination from the original Gears of War, but allows players to continue fighting after the leader has been killed, but losing the ability to respawn. Wingman splits all ten players into five teams of two, where both members of a team play as the same character. Submission, formerly known as Meat Flag, is a version of capture the flag in which players attempt to "down" an enemy controlled by the game's AI and move its body to their team's base or objective to earn points. The 10 maps shipped with the game originally are Avalanche, Blood Drive, Day One, Hail, Jacinto, Pavilion, River, Ruins, Security and Stasis. A Halo-like matchmaking system has been utilized for the online multiplayer. Players can now engage in multiplayer scenarios with any combination of human players and artificial intelligence controlled by the game, with the ability to set the AI's intelligence level. Horde is a new co-op mode for five players, fighting off waves of attacking Locust together, with each wave becoming more difficult. Horde Mode does not feature bot support as in competitive multiplayer, and can be played alone.

Players can pan around a map as the camera focuses on areas of intense fighting, and the Ghost Cam allows a player to roam freely around a map. The ability to take photographs is also featured, which enables the player to take a photo, which can be uploaded to the Gears of War website and is rated on the quality of action in the shot.

Synopsis

Setting Gears of War 2 takes place six months after the detonation of the Lightmass Bomb at the end of the first game. Though most of the underground army of the Locust Horde was destroyed, the explosion also caused much of the liquid Imulsion underground to vaporize, causing a fatal disease called Rustlung to spread among the diminished human population. After months of peace, the cities of Tollen and Montevado suddenly and mysteriously disappear underground, leading the Coalition of Ordered Governments (COG) to suspect the resurgence of the Locust. Soon after, the once impenetrable Jacinto, one of the last remaining safe havens for humans, begins to show signs that the same fate awaits it. To stop the fall of Jacinto, the COG responds with a large-scale counter-offensive against the Locust. Senior Producer Rod Fergusson says "In order to save Jacinto, [the COG] have no choice but to take the war to the Locust."

Characters Returning characters includes the main protagonists of the series Marcus Fenix and Dominic Santiago and others from the first game, including Marcus and Dom's fellow Delta Squad COG soldiers, Augustus 'Cole Train' Cole and Damon Baird. Also returning in supporting roles are radio dispatcher Anya Stroud and senior officer Colonel Hoffman. Lead designer Cliff Bleszinski confirmed that the character Carmine would be returning, but did not reveal how or in what capacity as Carmine was killed in the original Gears of War. It was later revealed that the original Anthony Carmine would not be present in the Gears of War 2 campaign, but rather his brother, Benjamin, would make an appearance. The game also introduces several new characters. They include Chairman Prescott, the noble, yet near-dictatorial military leader of COG; Tai Kaliso, "a spiritual and meditative warrior from a tradition of honor bound fighters;" and Dizzy Wallin, a former Stranded who joined the COG to keep his family safe. Dom's wife Maria also makes an appearance, and Dom's search for her plays an important part in the story.

Plot

As Gears of War 2 begins, the COG army mobilizes forces to deploy into the depths of Sera, known as the Hollow, to assault the Locust directly. Delta Squad, consisting of Marcus Fenix, Dom Santiago, Benjamin Carmine, Tai Kaliso, Augustus Cole and Damon Baird; fight the Locust alongside thousands of Gears. During the battle, Tai is taken prisoner by Locust general Skorge and is tortured to the point of insanity, resulting in him committing suicide after being rescued by Delta. They discover that the Locust are using a giant Riftworm to sink human cities. The Locust plan to destroy the rock structures in the outskirts of Jacinto, the last major human city, in hopes of sinking it underground. Delta kills the Riftworm from within before it can sink Jacinto, but they lose Carmine in the process.

After returning to the surface, Colonel Hoffman informs Delta that they failed in locating the Locust stronghold, but reveals Chairman Prescott declassified an intel file on an abandoned COG outpost that should have a lead on the location of the Locust capital and their queen. Delta is ordered to investigate and learns that the outpost is the New Hope Research Facility, a genetics lab dedicated to studying human children of Imulsion miners suffering from Rustlung. The experiments there resulted in the children becoming human-animal chimeras called Sires. Delta finds that the New Hope scientists relocated to the nearby caves of Mount Kadar to continue their research after being shut down by the COG. As Delta enters Mount Kadar to infiltrate the Locust stronghold, Dom gets a lead on his missing wife, Maria, located at a nearby prison camp. Dom finds Maria in a vegetative state due to the aggressive and invasive torture techniques of the Locust. Dom euthanizes Maria and continues on the mission.
