Getting started

Listing those that are in print.
After the Bomb (ATB)

Or

Heros Unlimited 2 (HU2) the mutant animal section.

For the Martial Art portion of the genera ether Ninja & Superspys or Mystic China for the Martial Art Forms.
Or if you want simpler, the h2h's in Rifts Japan or the h2h section in the RGMG or RUE
Or if you want weird, Rifts China 2.

Also, it helps to give PCs a 60 Bio-E bonuse over what's alotted in the book. I find that allows players to make characters that are closer to what you will see in fiction like TMNT.

Here's the base book...

It's the latest revision, informally known as After the Bomb 2 around here (I tend to abbreviate it as AtB2).

It condenses most of the animal psionics into one book, so you don't have to collect all the old books for those. It greatly expands on the animal abilities from the old version, even adding "vestigial disadvantages", such as diet restriction and things like a long tail with a mind of it's own, which give you more Bio-e. So for your power gamers there's a lot of potential.

If you want some extra flavor, I have a bunch of home-brew AtB2 weapons for mutants of various sizes as well as the Empire of Humanity. Just send me a message with your e-mail and I'll send them to you.

I believe there are some more animals written up for ATB in the Rfters somewhere.

We're trying for more of a TMNT feel than a post-apocalyptic scene.

But thanks!

then i'd suggest buying Heroes unlimited. if superheroes in the setting aren't your thing, you could buy After the bomb 2 and a copy of Ninja's and superspies, and use the setting and OCC's of Ninja's&SuperSpies with the after the bomb mutant animal rules. (just roll up a mutant animal, and instead of picking a background and class in AtB, pick one from Ninja's and super spies.)

Far as I can see all the suggestions were based in "these are the books you need for the game mechanics and base animal listings" along with H2H & MAF resource books.

Since the TMNT books are out of print, the closest book to them is the HU2 main book as far as setting and having the Bio-E rules goes.

ATB: base animal listings and Bio E mechanics and animal Psi, animal abilities, vestigial disadvantages
N&S: MAF
MC: MAF
RJ: MA h2h's
RC: weird MA h2h's
ATB sourcebooks: Base animal listings.
Rifters: Dino base animal listing (I think)
