<u>Playing Tips ('''WARNING - SPOILERS''')</u>:
When the Dark Realm Statue has been defeated, all of the Altar Assassins on the stage will lose their dark skin flair and they can then finally be damaged and killed. Each wave is over once all Altar Assassins on the map have been defeated. Defeated Dark Realm Statue pillars will be shown as broken in half afterwards. Once Wave 1 is over, repeat the whole process over again on each remaining wave.</div>
