It's like a photon, but green, right? And it does slightly more damage to Undine. Is that all there is to it? Is it worth getting at Mk XI and using over other torpedoes?
I assume you're asking about the bio-molecular torpedo? I have the Mk XI on both my romulans, and will use it until I get the rep high enough for the romulan reputation torpedo. Infocard says its a slightly-modified photon torpedo, with inherent +20 accuracy, and a delayed effect for killing target crew (slowing the target's repair rates). It works very well with torp spread III.
