But as you pointed out, a more realistic rule would be pretty boring. Thus, if a referee wants to use their somewhat stylized overpenetration rule, they can do so.
I don't see the harm in including it. And really, that's probably the most minor bit of the whole product. In terms of rules, the aiming option is my favorite, but the core of the book is a set of previously unseen variations on gauss weapons. Those variations are interesting and well done. Thus, I eagerly await the laser issue. And I hope they do a TL 8-11 slugthrower book too (earlier TL slugthrowers are handled fine in CSC and any number of real world gun sources).
And for the record, I'm not, nor have I ever been, affiliated with Terra/Sol Games. :wink:
