For Honor gets an impressive-looking training mode later today.
As someone who put a lot of time into Ubisoft's unique multiplayer-focused melee combat game at launch but drifted away a few months later, this new training mode is welcome. I can also see it being pretty useful for newcomers because For Honor has quite a lot of hero characters to contend with and plenty of mechanics that govern the combat to wrap your head around.
The new tutorial includes basic apprentice training and more advanced warrior training, which come complete with their own set of rewards. Usefully, the training includes timing feedback for opponent moves, which should help you master execution. There's also a media section, where you can watch tutorial videos.
