Fire Emblem Heroes has proven to be something of a sleeper success for Nintendo; while it's not in the same league as Clash of Clans or Angry Birds, it's ticking away nicely and earning cash for its creator regardless.

Nintendo is giving the smartphone game a fresh push at the moment with new events, and the company has also  produced this lavish live-action trailer which gets across the epic nature of the strategic gameplay.

Will this new promotional drive convince you to pick up the game again if you've forgotten about it, or have you been a seasoned player since launch?
