While many Pokémon fans are still buzzing about Pokémon Go, over 1.5 millions fans downloaded the fan-made PC game Pokémon Uranium in the past week. Unfortunately for the developers, who spent nine years working on the game leading up to its free release on August 6, the game fell under Nintendo’s radar. The company requested that the developers remove the download links to the not for profit game, and they complied.

Pokémon Uranium is only one of many fan-made Pokémon games floating around the internet, but it boasts some never before seen features. The most notable are new Nuclear type Pokémon; super-effective against all types but also weak to all move types (yes, that includes Normal). Nuclear types are aggressive and wild, and it is the trainer’s mission to save the world from destruction at the hands of Nuclear type Pokémon. All this, of course, while earning gym badges and becoming a Pokémon Master.

With the new type comes over 150 new fan-created Pokémon in the brand new region of Tandor. Trainers can be male, female, or neutral. Other features include online battles and trading and a Pokémon speech translator.

After receiving the takedown requests from Nintendo, the game development team posted a download statement on their website. The statement says “After receiving more than 1,500,000 downloads of our game, we have been notified of multiple takedown notices from lawyers representing Nintendo of America. While we have not personally been contacted, it’s clear what their wishes are, 

and we respect those wishes deeply. Therefore, we will no longer provide official download links for the game through our website.” They caution about the risk of attempting to download the game from unofficial sources, and then go on to say “We are blown away by the response this game has received, and we thank you all so much for your outstanding support. We will continue to provide Pokémon Uranium-related news and updates through our official channels.”
