- Story***
You play the adventures in the series as a captain of your choice. The captain was on his home planet on a camping trip with his friend. He strayed away from the site and returned only to see his friend had been knocked out and the entire camp site was destroyed. Seconds later, a ship came down and brought the player on board. Now, your goal is to find 100 keys on 100 planets and talk to the killers to bring back your friend.
- Characters***
-Captain- The player plays as the captain. The captain goes out in every mission to find the key on each planet. After each mission, the player gives the key to the Leader -Leader- The man that took the player in. Keeps hold of all of the keys the player collects. -Steve- A character that appears on the ship every mission. Since the 5th Planet, he has told the player the planet's atmosphere, temperate, name, number, and the mission's difficulty.
- Easter Eggs***
Since Planet 2, there has been a teleporter (usually near the home base you start on) that leads to a part of the planet that is much off course. At this location, there is always a creature named "Easter-Egg" that tells you a hidden fact, usually relating to the 100 Planets series. After talking to Easter-Egg (not required), there will be a teleporter that takes you back to exactly where you started the mission.
- Comets***
Little is known about Comets. However, since I created the series I know everything about them. Comets were an idea I had around the start of the 100 Planets series. I planned on making a comet for every planet. The comets work a lot like the ones in Super Mario Galaxy, in which they use the same planet and throw in a slight new type of difficulty. Sometimes, every creature would turn into an epic. Other times, they might force the player to play as a flightless creature. I posted 4 comet adventures. One explaining comets, another being a comet version of the Intro Adventure, and the other 2 being the first 2 planets. So far I've made a comet of the first 5 planets (3 of which were never published). I decided, however, to cancel the comet project all together. The adventures were removed, the Sporecast taken down, and almost no evidence whatsoever remained about comets (However, Planet 4 still ends with the Leader telling the player all about comets). I still plan on releasing the '100 Comets' series. But it will wait until after the '100 Planets' series is over. The reason: I don't have the time to make a Comet right after I make a new adventure.
