I've been wanting this since Assassins Creed 2 ended. There's an artist online, Jason Kang, that did some beautiful fan concept art for this idea. Really wish Ubisoft would reach out towards Asia. Lots of locations that would work beautifully with AC's game mechanic.
The setting is set in Korea during the Japanese Occupation through the course of the early 1900’s.
"To give a little summary of the idea for my game, the setting takes place mainly in Korea during The Japanese occupation which occurs during the time period of 1910-1945. There's a lot of things happening during this time period and in this corner of the world, the biggest being World War II, which is why I thought it would be a great era to base a game off of.
My story starts by showing how the main character, Arang, and her sister are forced into becoming comfort women by the Japanese and are sent to the battle camps stationed in China with hundreds of other kidnapped women during the Second Sino-Japanese War. Arang and her sister try to escape and although she does her best to protect her, her sister is killed by the pursuing soldiers. Arang is then rescued by the brotherhood of Assassin's in Manchuria and through difficult training, she gains all the skills she needs to help liberate Korea from Japanese rule."
