What is it? A melee-action game packed with lots of violence. It's mainly aimed towards PvP so if you're a fan of how the fighting works in Mount & Blade with loads of AI to kill then you're in for a bit of a treat. There will be a campaign mode.
What's in it? As the picture above suggests the three factions will be, 1. The knights, 2. The samurai, 3. The vikings.
