A mobile battler Fire Emblem Heroes has a steady stream of new heroes and this trend is not going to end anytime soon. Nintendo have now dropped a new trailer and they've announced that four more characters are joining the roster.

The Princess of Bern update sees the arrival of Melady (Captain of the Guard), Dieck (a muscle-bound mercenary), Merlinus (the traveling merchant), and lastly, the Princess of Bern herself - Guinivere.

Along with the new characters, we are getting a new story prologue titled "Reality", which sees Freyja bearing dreadful news about Prince Alfonse. Can we trust her? There's only one way to find out and you know what that is.

Fire Emblem Heroes is available now on Android and iOS devices.
