User blog comment:Attackforce/CA: EU Halloween Update/@comment-4122395-20111027215312

Gray and Black Cases are Cauldrons, Halloween event cases. I don't think that will be the revamp they said in the Stage 3 update. From yellow cauldrons (grey cases) I got 6 times 10x100% exp passes :) and 1 Hockey Mask, that is currently bugged. Most textures are bugged now in CA EU. I don't think they intended to apply the patch, but to add only some things for the event. Lobby background without textures, hockey mask without textures (you seem to wear nothing, but it gives stats), the new shotgun in the forging list but unforgeable (error when you try, I tried myself).
