In one of the more surprising crossovers to come down the pike, Nintendo and Atlus have announced a new role-playing game for the Wii U based around the Shin Megami Tensei series and Fire Emblem series. Not much is known about the project, dubbed Shin Megami Tensei X Fire Emblem, except for what was shown in the brief trailer above, which Nintendo recently debuted during Wii U Direct.
