Things are about to get weird—in the best possible way. Teenage Mutant Ninja Turtles Transdimensional Adventures Redux Edition is a massive, 256-page hardcover sourcebook collection that sends your TMNT campaigns hurtling through time, space, and dimensions you probably shouldn’t touch (but absolutely will).

This Redux Edition gathers Transdimensional TMNT, Teenage Mutant Ninja Turtles Adventures, and TMNT Guide to the Universe into one beautiful volume. Inside you’ll find rules for time travel, spaceship creation, dimensional magic, and a stack of adventures that can take your turtles just about anywhere. On top of that, there’s a treasure trove of bonus content including tribute artwork, written memories from TMNT creators, and a few surprises waiting between the pages.

The book is fully loaded with artwork by Kevin Eastman and Peter Laird—including two 10-page comic strips originally created for these sourcebooks—along with art by Kevin Long and a whole crew of incredible creators. New artwork from Jim Lawson, Ben Bishop, Freddie E. Williams, Sophie Campbell, and many others brings everything together in full, glorious color.

If you’ve ever wanted your TMNT game to include time paradoxes, cosmic weirdness, and dimension-hopping chaos, this book delivers. Big ideas, bigger adventures, and turtles everywhere.
