PvP content has been added to Spiral Knights with the the launch of King Krogmo's Coliseum, a battle sport arena that allows Knights to duke it out for prizes. The object of the first game, Blast Network, is to eliminate your opponents with your bombs. Simple enough, right?

To commemorate the new addition, SEGA and Three Rings will be awarding the Spiral Bombhead Mask to all players who complete their first PvP battle, regardless of the match’s outcome. There are a variety of Bombhead Masks to collect, so head over to the Coliseum and start blowing up other players! More games, rewards and features will be added to the arena in the future.
