關於此遊戲

• No Story, No Worry - You don't fight because you were called to war, there's no nation to save or kittens to rescue. You fight because you want to.
  
• Adventure Alone or in Groups - Adventure together, with up to eight players at once. Warman can be Warmen (or Warwomen).
  
• Freeform Class System - Archer, Warrior, Bandit, Fire Mage, Wind Mage. Each class has unique skills and passive ability tree. Want to switch? Go from burning monsters to cutting them up just by swapping weapons.
  
• Endless Loot - Every item can drop with modifiers, letting you grow your character. There's always room for further growth. Don't like an item? Go visit the Blacksmith and reforge it!
  
• Mayhem for Fun and Relaxation - Want to be overpowered? You can be overpowered, if you're clever enough. Sky's the limit when it comes to stacking modifiers and reaching ludicrous power levels.
  
• Travel the World, See the Dungeons - 17 interconnected maps across 3 biomes await, each offering unique challenges, monsters, and a mix of handcrafted and procedurally-generated dungeons for the ambitious adventurer!
  
• Death is a Slap on the Wrist - Death happens. Pick yourself up, brush off the blood, then go back into the fight, because you don't lose your gear if someone manages to smear you on the dungeon walls.
