7th Dragon 2020 (2011)

7th Dragon 2020 is a Japanese role-playing game and a spin-off sequel to the original 7th Dragon. It changes the setting from 7th Dragon's generic fantasy world to post-apocalyptic Tokyo, and ditches the 2D sprites for an entirely 3D graphics. Despite the change in setting, the basic story is largely identical - the world has been invaded by dragons, bringing with them a brand of poisonous flowers. As a group of survivors known as Murakamo 13, you must search through the wreckage of the various districts of Tokyo to find other refugees, kill lots of dragons, and contend with a rival group of humans known as SKY.
