But you won't yet fight for honor
It's not hard to figure out your motivation in For Honor. It's eponymous, it's right there in the name. You fight for honor, a prize of the spirit that transcends anything material. Honor isn't easy to attain, though. It's one of those coveted qualities like glory or heroism that take a lot to achieve; but, once you have it, it takes a monumental fuck-up to lose.
For Honor has a taste for the valiant, but it's not enough to call yourself honorable. There's a beta running from January 26 through January 29 on PC, PS4, and Xbox One. Sign up here if you're interested.
The premise of the beta is a War of the Factions event where vikings, samurais, and knights battle each other for supremacy -- but not yet for honor. That's a more arduous road, one that can't be traveled in a single weekend.
