About the Game

Warmaster Seerus is the evil master of munitions within the gremlin's all-powerful Crimson Order. Thought to be the true mastermind behind the Roarmulus Twins and countless other gremlin weapons, he is the Crimson Order’s creator and supplier for their diabolical engines of war.

Recon Knights under the command of Lieutenant Feron recently discovered Seerus’s ‘Grand Arsenal,’ his development center and storage facility for all his weaponry. Now, Feron himself is leading several squads of knights directly into the Grand Arsenal, with the intention of weeding out Seerus and destroying his war machines.

Met with heavy resistance, Feron’s squads require reinforcements and Spiral HQ is sending you in to assist.

This is pretty much the pinnacle of what any MMO expansion should be, especially in a game like Spiral Knights. It is optional, the content is only as functional as you earn it to be-- There are no free boosts just for paying. It's got new music, new art assets, new enemies, new mechanics, and a very tight flavor and theme. It does not hurt that it's fun as hell and the rewards are top-notch.
