Youtuber user DrLilRobot and his team of geniuses, have developed a mod for Team Fortress 2 that plays exactly like Nintendo's Splatoon.
If you do not own a Wii U console this may be the closest you will ever get to playing the modern Nintendo classic.
The mod is not perfect however, while you may be able to dive in your splattered paint shots as a squid, the paint is blocky and square in comparison to the more natural splat you will find in the Wii U version.
Considering this is a fan created mod it's rather impressive! Let's hope Nintendo does not send these guys a C&D letter.
