Quick Background Information from Wikipedia Article to get you In The Mood!

From, Activision, this is to be the tenth main installment in the Call of Duty series, and the sixth developed by Infinity Ward.

Campaign

The player will assume the role of a character dressed in a military Ghost uniform known only as Hesh. However, Infinity Ward's executive producer Mark Rubin has stated that Hesh is not the character's final name and is just a place holder until the studio can come up with a better name.

Multiplayer

As confirmed in the behind-the-scenes video released by Call of Duty, the multiplayer in Call of Duty: Ghosts will not be like the previous Call of Duty games.[how?] New mechanics have been added to the multiplayer. Maps now have areas that can be altered or destroyed. 

On certain maps, there is a Nuke-like kill-streak,the Odin Strike, that can be used by killing the top player on the other team and then completing various challenges after picking up a briefcase that is dropped. The sniper-rifle scopes will also have new "dual render technology" allowing the player to see around the outside of the scope when zoomed in. On October 3, a new multiplayer type was revealed, called Squads. 

This features a squad that you build and you can face other squads around the world. Your squad can be leveled up and will act like a true individual. There have been six confirmed maps so far. "Strikezone", "Octane", "Whiteout", "Stonehaven" and "Chasm" are the five confirmed maps that are in Call of Duty: Ghosts so far. The dynamic map, "Free Fall", is a pre-order bonus. It has also been revealed that the game will feature playable female soldiers.
Multiplayer game modes

Call of Duty: Ghosts brings back a number of fan-favorite modes, while introducing seven new game types, including:

Search and Rescue: A take on Search & Destroy, but rather than having a single life per round, in Search & Rescue a player's team can revive them. It combines that teamwork and communication from Kill Confirmed with the objective-based cooperation of Search & Destroy.
    
Cranked: In this team-based game mode, the player has to kill an enemy which triggers a timer. The player must get another kill before the timer reaches zero, otherwise they die. The player's movement is enhanced in this game mode.[9]
    
Free for all: The classic gamemode from previous installments in the franchise returns in Call of Duty: Ghosts, in which players must rack up a total of 30 kills to win the game against seven other opponents or rack up to most kills in a 10 minute time limit.
   
Team Deathmatch: Team Deathmatch returns in Call of Duty: Ghosts: two teams, 10 minutes, 75 kill limit.
    
Search and Destroy: A gamemode in which one side has five minutes to plant a bomb at a choice of two sites and the other team is tasked with defending the sites, the catch of this mode is there are no respawns and the game ends once one team wins four rounds.    

Domination: A gamemode where three flags are scattered throughout the map for players to take and control. Every two seconds a flag in controlled will gain a player's team a point, if a player's team controls two or three flags they gain two or three points. The first team to 200 points or the team with the highest amount of points after 10 minutes wins.
    
Kill Confirmed: A gamemode in which two teams battle, similar to TDM, with the catch being that when a player kills an enemy they drop a dog tag, which is worth points when collected. If a player collects a fallen teammate's dog tag, no points are award to the enemy team; first team to 100 points wins the game.

Infected: Same as Modern Warfare 3 infected.
    
Grind: No Information    

Blitz: This team-based game mode is similar to Capture the Flag in that the player needs to go to a portal located at the enemy's spawn point while preventing players from the enemy team from reaching theirs. These portals are temporarily closed when they are captured to prevent players from rushing.

Hunted: No Information 

Plot

A playable German Shepherd dog is part of the player's squad.

San Diego is kinetically bombarded by an American space station called the Orbital Defense Initiative (ODIN),[9] after being hacked by a group called the "Federation", resulting in what becomes known as "The Event." As a result, the global balance of power changes: Many countries are decimated, geographical landscapes have changed, and the United States doesn't exist as a superpower. American industries and infrastructures are devastated, casualty ratings are critically high, and the contiguous United States is made vulnerable.[7]

In 2023, the "Federation" (consisting mostly of South American regions) emerges as the world's dominant superpower, invades the crippled United States, and overwhelms their military. With its military crippled, state territories falling, and government structure collapsing, America is losing the war, but remnants of the U.S. military aren't giving up without a fight, so they all created a specialized unit called the "Ghosts", led by a retired U.S. Army captain, Elias Walker (Stephen Lang). He is joined by his sons, Logan and David Walker, American soldiers, along Booth and Neptune, a trained German Shepherd named Riley, and a U.S. Navy SEAL commander, Thomas A. Merrick.[7]

The "Ghosts" are an elite paramilitary force of former U.S. special forces who became more skillful than the Federation's military forces that are capable of waging dangerous guerrilla warfare, clandestine operations, and infiltrations behind enemy lines, even on their mainland, to eradicate all threats in order protect what remains of the United States. These soldiers are determined to keep the existences of the United States and to destroy the Federation by hunting down their leading members, Almagro and Rorke, and to hack the Federation's newly developed space station, "Loki" to completely annihilate them to re-establish American superiority over the world once again.
