Binding of Isaac Planetarium

Here comes one of the most exciting and mysterious chambers of Binding of Isaac game. It appears in the Antibirth chapter and can be unlocked with your efforts. Let’s be honest – entering Planetarium is not that easy. It is pretty challenging to meet all the criteria that will help you open up the room. You need to have the key to enter, just like you do with any of Treasure Rooms. To unblock the room, you should gather three items that are related to astrology theme. They are a Crystal Ball, Magic 8 Ball, Tiny Planet, and Zodiac. Only if you have three of them, you can get access to Planetarium. A rare player has seen this room, since appearing there has a small chance – only one percent. Still, you will have 21% of probability in case none of Treasure Rooms were visited before. You should skip entering one and opt for Planetarium. Only one of them can become yours. Also, you can enter this room without skipping Treasure Rooms in case you spawn at violet areas at Mausoleum. In general, Planetarium is something like another Treasure Room, but it is packed with special astronomy objects that cannot be seen anywhere else. In addition, they include Signs of Zodiac, rare symbols.
The story of this room started on Reddit, when one of the users requested a mod on this topic. The objects inside of this room reflect cosmic bodies from the Solar System. There are planets out there, including Mercury, Pluto, Mars, Venus, etc. Also, there are Sol and Luna that represent the Sun and the Moon. Two planets are not included into the list. These are Neptune and Jupiter, so you won’t find any items marked as these celestial bodies in Planetarium. On the other hand, there is Pluto here, present as a planet, even though it is no longer considered as a planet by the modern science. The names of all items are written in Latin, but you will easily recognize most of them, since they are used in our modern language, as well. Or, at least, they hint the right meaning, so you will hardly get lost here. Each planet gives you a unique ability. For example, the Sun will recharge the character and provide luck points. The Moon adds another Secret Room on every floor you visit. Mercury allows Isaac to leave the rooms whenever he wants to, even if there are enemies on his way. Venus confuses your enemies and makes them attack one another. Earth, or Terra turns character’s tears into stones and helps him destroy the obstacles and attack the enemies. Enjoy the mod!
