Call of Duty: Modern Warfare 3
Call of Duty: Modern Warfare 3 is a first-person shooter video game. It is the eighth installment of the Call of Duty series and the third installment of the Modern Warfare arc. Due to a legal dispute between the game's publisher Activision and the former co-executives of Infinity Ward – which caused several lay-offs and departures within the company – Sledgehammer Games assisted in the development of the game, while Raven Software was brought in to make cosmetic changes to the menus of the game. The game was said to have been in development since only two weeks after the release of Call of Duty: Modern Warfare 2. Sledgehammer was aiming for a "bug free" first outing in the Call of Duty franchise, and had also set a goal for Metacritic review scores above 95 percent.
The game continues the story from the point at which it ended in the Call of Duty: Modern Warfare 2 and continues the fictional battle story between the United States and Russia, which evolves into the Third World War between NATO allied nations and Ultra-nationalist Russia (a revolutionary political party idolizing the late days of the Soviet Union).

By then, it had been in development for two years. Call of Duty Online is free-to-play for mainland China and is hosted by Tencent. Since Activision had lost the publishing rights to Call of Duty and several other franchises in China due to a legal dispute on most of the Western gaming consoles (Xbox 360, PlayStation 3, and Wii), it had been rumored that it would be Microsoft Windows-exclusive, since PCs hold the dominant share of gamers in mainland China.
Call of Duty: Combined Forces
Call of Duty: Combined Forces was a proposed concept draft originally intended to be a sequel to Call of Duty: Finest Hour.

The game was projected to cost $10.5 million to produce after Finest Hour was complete. Eventually Activision deemed the pitch as more of an expansion than something entirely new, causing the company to reject the proposal and end their contract with Spark Unlimited shortly after.

Call of Duty: Roman Wars

The game was set in ancient Rome, and allowed players to take control of famous historical figure Julius Caesar, along with "low grunts", and officers of the Tenth Legion.

The Call of Duty games were used in Esports, starting in 2006, alongside the game released at the time, Call of Duty 4: Modern Warfare. Over the years, the series has extended with releases such as Call of Duty: World at War, Call of Duty: Modern Warfare 2, Call of Duty: Black Ops, Call of Duty: Modern Warfare 3, Call of Duty: Black Ops II, and Call of Duty: Ghosts.

Players can compete in ladders or tournaments. The ladders are divided into several sub ladders such as: the singles ladder, doubles ladder, team ladder (3v3 – 6v6) and hardcore team ladder (3v3 – 6v6). The difference between the regular team ladder and the hardcore team ladder is the in game settings and thus a rule differentiation. Winning ladder matches on a competitive website rewards the user with experience points which add up to give them an overall rank.
The tournaments offered on these websites provide players with the opportunity to win cash prizes and trophies. The trophies are registered and saved on the player's profile if/when they win a tournament and the prize money is deposited into his or her bank account. Call of Duty: Ghosts was the most competitively played game in 2014, with an average of 15,000 teams participating every season.
For the past 6 seasons in competitive Call of Duty, Full Sail University has hosted a prize giveaway, giving $2,500 to the top team each season. The other ladders give out credits and medals registered on players' profiles. Tournaments hosted on the Call of Duty: Ghosts's Arena give cost from 15 to 30 credits, thus averaging at a cost of about $18.75 per tournament. If the player competes with a team, the prize money is divided and an equal cut is given to each player. Other tournaments with substantial prizes are hosted in specific cities and countries for LAN teams.
Playing Call of Duty competitively is most popular in Europe and North America, with users who participate in tournaments and ladder matches daily. Competitive players have an average of 500,000 followers on social media.
Call of Duty Endowment
The Call of Duty Endowment (CODE) is a non-profit foundation created by Activision Blizzard to help find employment for U.S. military veterans. The first donation, consisting of $125,000, was presented to the Paralyzed Veterans of America.
Co-chairman General James Jones is a former U.S. National Security Advisor. Founder Robert Kotick is the CEO of Activision Blizzard. Upon its founding in 2009, the organization announced a commitment to create thousands of career opportunities for veterans, including those returning from the Middle East. Annual awards given by the endowment include the “Seal of Distinction,” a $30,000 initial grant given to selected veteran’s service organizations. In November 2014, the endowment launched the “Race to 1,000 Jobs” campaign to encourage gamers to donate money to and get involved in organizations that provide veterans with services. As of 2015, the Call of Duty Endowment had provided around $12 million in grants to veterans’ organizations in the United States, which has helped find jobs for 14,700 veterans.
On March 30, 2010, CODE presented 3,000 copies of Call of Duty: Modern Warfare 2, approximately $180,000 in value, to the U.S. Navy. The copies were delivered to over 300 ships and submarines as well as Navy Morale, Welfare, and Recreation facilities worldwide.
