When it was first released, FusionFall required a paid subscription for the full game, with a limited portion of the content available to free accounts. Free accounts could only play in the "future" portion of the game, which only allows players to collect four nanos and create two characters. The full game had a total of 36 nanos before the new extensions. The game now has a more than 40 nanos. To create up to four characters, players had to earn all 36 nanos during the beta testing. Players with characters that progressed into the past during the sneak peek or during a previous subscription had their characters locked until a current subscription was purchased.
Subscription plans included one-month, three-month, year-long, and family plans. The FusionFall Victory Pack Exclusive was made available for purchase when the game was released. It contained a four-month subscription, as well as a game guide, T-shirt (if bought from GameStop), and exclusive outfits and weapons for the player's character. The Victory Packs were eventually discontinued, having been replaced with one-month and three-month game card available for purchase at Target outlets. The game was made completely free on April 19, 2010, making everything a member could have available for free. In 2011, the game gave the player a Clockwork set (not based on Clockwork from Ben 10). It only counts for subscribers and can only be accessed with a code.
A comic prequel, co-written by Matthew Schwartz and Megas XLR co-creator George Krstic, entitled FusionFall: Worlds Collide!!, was passed out during Comic Con '07. Due to the overwhelming success of the comic, George Krstic is in talks to write a script for a FusionFall feature based on the comic to accompany the game's launch. The manga used to be available on the official website for public viewing and in PDF format for download. It covers the events leading up to the start of the game.
FusionFall was shut down by Cartoon Network on August 23, 2013. However, the game has been revived by a group of fans and has been renamed FusionFall Retro: https://www.fusionfallretro.com/
