About Call of Duty Modern Warfare 3

The best-selling first person action series of all-time returns with the epic sequel to multiple “Game of the Year” award winner, Call of Duty®: Modern Warfare® 2. In the world’s darkest hour, are you willing to do what is necessary? Prepare yourself for a cinematic thrill-ride only Call of Duty can deliver. The definitive Multiplayer experience returns bigger and better than ever, loaded with new maps, modes and features. Co-Op play has evolved with all-new Spec-Ops missions and leaderboards, as well as Survival Mode, an action-packed combat progression unlike any other.
The player assumes the role of various characters during the single-player campaign, changing perspectives throughout the progression of the story, which, like its predecessors, is divided into three sets of missions called "Acts". Each mission in an act features a series of objectives that are displayed on the heads up display, which marks the direction and distance towards and from such objectives. Damage to the player is shown by the percentage of blood splatter shown on the screen. The player's health regenerates over time. Mission objectives vary in their requirements, ranging from having the player arrive at a particular checkpoint, to eliminating enemies in a specified location, to standing their ground against enemy squadrons, manning mini-guns and other weapons, and planting explosive charges on an enemy installation. Some of these objectives can be failed, and may or may not hinder progression of the story. The player is also accompanied by fellow soldiers who cannot be issued orders.
Get ready to enjoy this great classic again with its new improved edition that recovers its campaign and game modes and adds a lot of new content.

    Other stores may take 30–40 minutes depending on game availability. On release days, delivery times may be slightly longer.

    If you notice an unusually long delay, contact the store or us, and we’ll resolve it as quickly as possible.

The game is exciting and rewarding, but the series' signature thrills have lost some of their luster1. Modern Warfare 3 iterates rather than innovates, so the fun you have is familiar1. By sticking to the series' strengths, Modern Warfare 3 delivers some of the best competitive, cooperative, and single-player shooting in the business2.

The shooting game in question is plagued with numerous issues that significantly hinder the overall gaming experience. From my perspective, the game seems to suffer from a plethora of technical glitches, ranging from frequent crashes and laggy gameplay to unreliable servers that disrupt online matches. Moreover, the game's design appears rushed, with poorly balanced weapons and unimpressive graphics, detracting from the immersive quality one expects in a modern shooter. The lack of innovative features or engaging storyline exacerbates the overall disappointment, rendering the gameplay repetitive and uninspiring. It's disheartening to see a potential-filled shooter fall short due to these pervasive problems, leaving players frustrated and dissatisfied. Hopefully, the developers will address these issues promptly through updates to salvage the game's reputation and provide a more enjoyable gaming experience for its player base.

Call of Duty Modern Warfare 3 has a plenty of similarities in comparison to Modern Warfare 2, as graphics did not improve a lot and most menus look almost alike. But that is not true. After playing the multiplayer you can immediately feel, that the game is much more balanced. Developers brought us some really great innovations such as different types of killstreak packages, which suit different playstyles. Gun customization was also expanded with weapon perks. Although MW3 uses a classic Call of Duty formula, the game is well made and provides players with hours of fun.

A mí me gusta menos que el el Modern Warfare 2, la historia está bien, pero no tanto como la de la segunda entrega, aunque entiendo que haya gente a la que le guste más. Sin embargo, está muy chulo el modo en el que te llegan oleadas y oleadas de enemigos, me ha dado muchas tardes buenas con los amigos.

Still one of my favourite COD games. However I'd recommend getting BO2/BO3 for PC because MW3 has almost no players anymore.
