I have recently gotten the rules for first edition ( I am a second edition owner and have just recently rekindled my enthusiasm for SH) and have been unable to locate any of the original hybrib models. I have replaced the hybrids for our gaming sessions with spinegants (newer models that come in the box set with Hormagants) and based some of the weapons fire off the new new tyranid codex. Has anyone else adapted rules for some of the new tyranids? I have some of my own and was reluctant to post them in case there was some other version floating around. I have only taken my expanded rules up to Tyranid warriors as the others would seem to be to large to be stuck in a hulk. I remember seeing a variant rules on these but can't seem to find it again.
