Call of Duty 4: Modern Warfare (CoD 4) is a first-person shooter video game. Developed by Infinity Ward , published by Activision . The game was released on Xbox 360 , Playstation 3, Windows and Mac OS X and Nintendo Wii.
It was originally released in November 2007 in North America, Europe, Australia and Japan.
As opposed to earlier games in the Call of Duty series, the game features modern equipment and new features, many exclusive to the multiplayer part of the game, such as "killstreaks"; killing a number of enemies without the player dying in between kills allows access to various assets including airstrikes and helicopter support. A character can be positioned in one of three stances: standing, crouching, or prone; each affecting the character's rate of movement, accuracy, and stealth. Using cover helps the player avoid enemy fire or recover health after taking significant damage. As such, there are no armor or health power ups. When the character has taken damage, the edges of the screen glow red and the character's heartbeat increases. If the character stays out of fire, the character can recover. When the character is within the blast radius of a live grenade, a marker indicates the direction of the grenade, helping the player to either flee or toss it back to the enemy.
Infinity Ward released the Variety Map Pack for the Xbox 360 on April 4, 2008. It includes the multiplayer maps "Killhouse", "Creek", "Chinatown", and "Broadcast". The same map pack was released for the PlayStation 3 on April 24, 2008. The Variety Map Pack was downloaded by over one million people in its first nine days of release, a record for paid Xbox Live downloadable content, valued at US$ 10 million.
