Warriors Orochi, is a PlayStation 2 and XBOX360 action video game developed by Koei and Omega Force. It is a crossover of two popular video game series, Dynasty Warriors and Samurai Warriors (Specifically Dynasty Warriors 5 and Samurai Warriors 2). The game was released on March 21, 2007 in Japan, September 18 in the United States, September 21 in Europe, September 27 in Australia and September 28 in New Zealand. The game came out for the Xbox 360 in Japan on September 13, and the UK version came out on the same date as the Playstation 2 version in the United States.
Unlike the Dynasty Warriors games, the English language version of Warriors Orochi utilizes the correct pronunciations of the Three Kingdoms officers. For example, Cao Cao is now pronounced as "ts'au ts'au" instead of "cow cow" in the Dynasty Warriors series.
