Castle of Chaos is an action shooter game where you and your companion must shoot and hold your direction through more than 60 floods of enemies. The palace is under attack by beasts and ghosts! It's really up to you to get your weapons and start hitting them as a whole. You have to be careful though, the apparitions have to be shot with plasma firearms and the beasts have to be shot with slugs. You will need to change your weapons accordingly. Watch out for your ammo too! Assuming you run out of ammo, you'll be in danger of being overwhelmed. Each competitor also has their own finishing moves such as a rocket blast or Goliath's laser shaft. Try each person to see which one suits you best! Can you withstand every single one of Castle of Chaos' 60 hits at some point?

Remember how in times gone by, you and your companion could sit down at one of your #1 games for two to go on a perilous excursion, fighting for your planet with hordes of outsiders shooting at everything and everyone left and right. The new shooter is a continuation of this excursion, where again two of the most fearless shooters save the world from the invasion of beasts with new weapons and new beasts.
