No Treyarch made the game
Depends on which CoD, But the first one was made by Infinity ward. Other CoDs are made by Treyarch and others by Infinity ward Example: CoD 4: Infinity Ward CoD Black Ops: Treyarch
Treyarch and Infinity Ward both make games for Activision who does the series
infinity ward created only a few other games, but i don't remember them all
In a sense since they own Treyarch the developer of Black Ops. Activision insures that the games are released and are the Publishers of Call of Duty series. They also own Infinity Ward who develops Modern Warfare series of Call of Duty
Treyarch made Black Ops and Infinity Ward makes the Modern Warfare series. They do not work together although Treyarch did make the Modern Warfare Reflex Edition for Nintendo Wii to be released when they released MW2. Both companies are owned by Activision who publishes the Call of Duty Series.
Treyarch - Call of Duty Infinity Ward - Call of Duty 2 Treyarch - Call of Duty 3 Infinity Ward - Call of Duty 4: Modern Warfare Treyarch - Call of Duty: World at War Infinity Ward - Call of Duty: Modern Warfare 2 They take turns every year so no, Treyarch made CoD 3
Technically speaking, infinity is not a definable number, and therefore, it cannot be altered by multiplication.
Infinity Ward will make a new game for release in November 2013. On November 13 2012 Black Ops II will be released as the next Call of Duty series game. Black Ops II was developed by Treyarch. All Call of Duty Series games come from Activision, who owns Treyarch and Infinity Ward and is itself majority owned by a french conglomerate, Vivendi
Infinity Ward has been working on it, but the game will have many different versions just Like Call of Duty Black Ops did and Treyarch did not make all of the Call of Duty Black Ops game versions. Activision was responsible for releasing all the games worldwide on the same date and they will also release Call of Duty Modern Warfare 3 in all of it's different Game versions see related link Sledgehammer games and Raven Software are working with Infinity Ward toward the November 2011 release
Infinity ward makes better because they've won awards for every of their call of duty video games. Treyarchs only great games were black ops and nazi zombies before that they games weren't as good. Treyarch does make more violence which will amuse some people but infinityward started with the call of duty series and they took it seriously.
They did they just didn't make Black Ops which is not Modern Warfare title
Modern Warfare 3 will be released on November 8 2011 Call of Duty Black Ops was released in November 2010 Treyarch and Infinity Ward have both been making and releasing games in the Call of Duty series for Activision. Call of Duty Black Ops is the current record holder for most video game sales so of course Treyarch will release a new game in November 2012 Well Infinity Ward Have says there will be another call of duty but they didn't says if theirs will be the next one or if there will be one in between Modern warfare 2 & the unnamed project .But there are rumors that infinity ward & treyarch will come together and make a call of duty but that is only rumors .
