Call of Duty World at War
World at War received ports featuring different storyline versions, while remaining in the World War II setting, for the Nintendo DS and PlayStation 2. It was the first game in the series to feature the zombies mode featured in later sequels. A Windows Mobile version was also made available by Glu Mobile.
Information
The narrative for the campaign mode focuses on the Pacific and Eastern Front theaters of World War II, involving the United States, Empire of Japan, Soviet Union, and Nazi Germany. It is told from the perspectives of Marine Raider Private C. Miller, US Navy Petty Officer Locke and Red Army soldier Private Dimitri Petrenko, and is based on several historical battles. The multiplayer component of the game contains various game modes and a leveling system that allows the player to unlock additional weapons and rewards as they progress, similar to Call of Duty 4 and repeated in many following Call of Duty entries. Vehicles, in the form of tanks, that players can control appear on certain multiplayer maps. The game also contains downloadable content called “map packs”, which can be purchased online. A new feature to the series was the addition of a cooperative mode, which supports up to two players locally and four players online, as well as the introduction of the Zombies mode.
Development for World at War took two years and began after the release of Treyarch’s previous title, Call of Duty 3, which was also set in World War II and was their first title they developed for the series. The game is based on an enhanced version of the IW engine developed by Infinity Ward with increased development on audio and visual effects. Treyarch utilized the engine to make more parts of certain environments destructible and introduce limb dismemberment and realistic burns to character models. The game was announced by Activision on June 23, 2008.
World at War received positive reviews from critics, with praise directed at its intensity and violent nature, though it received criticism for its lack of innovation. It was also a commercial success, selling 3 million copies in the United States within the first two months of its release, becoming one of the best-selling titles of 2008. It also marked the beginning of the Black Ops subseries, as characters from the game were carried over into its sequel, Call of Duty: Black Ops (2010). The Xbox 360 version of World at War became backwards compatible on the Xbox One in September 2016.
Multiplayer
Call of Duty World at War
World at War’s multiplayer experience resembles the one established in Call of Duty 4: Modern Warfare. All versions of the game use a similar perk and ranking systemand feature six multiplayer modes, including team deathmatch and capture the flag.There are three “killstreak rewards” that can be used to turn the tide of battle: a recon plane, showing opposing players on the mini-map; an artillery strike upon an area; and attack dogs, which spawn and attack opposing players. These are gained with 3, 5, and 7 kills, respectively. They are available in all game modes, apart from team survival, and cannot be edited.
Gameplay in the multiplayer’s “War” mode
The game also features a cooperative gameplay mode with up to two players via split-screen on consoles, or four players online, for the first time in the franchise. The Wii version of the game does not include online co-op, but two players can play through a “squadmate co-op” mode which allows both players to experience the game through the same screen and point of view.
Call of Duty
The Call of Duty series has existed since 2003 and in addition to various spin-offs, including for the handheld systems Nintendo DS and Sony PSP, 14 major titles of the series have now been released. Ever since the first part of the series, great emphasis has been placed on the online multiplayer mode in addition to the single-player campaign, which is also reflected in the development of the shooter series. Since the first Call of Duty, World at War, which was developed exclusively by Treyarch, each part also included cooperative challenges that you could play together with friends. The latest installment, Call of Duty: World War II, also features an extended multiplayer mode that puts you and your friends in the combat zones and famous battles of World War II. Using the divisions, you’ll be able to choose between the deadly sniper and the brute armored division and support your comrades in battle. In addition, World War II also has a zombie mode “Nazi Zombies”, as in its predecessor Call of Duty: Black Ops. Face the monsters of the Third Reich and win glory and honor.
