The shape of the Zeus is the only one that's really... fit for the role, I think.
Even that is a bit iffy.
Perhaps a better explanation is needed.
It's a joint project between the BMM and Ageira, so it's probably safe to say it would have major Bretonian influences in it's design.
However, with Ageira being the main designers, it wouldn't be as uhh... 'fishy' as other Bret designs.
Definitely looking for something sleek like the current model.
I like the look of the Zeus design, and I think it could make a great ship if modelled well, I'm just not sure it's right for the Havoc.
