You may want to file off some serial-numbers on the titan nomenclature, there.
How feasible would it be to make an Ogre/Bolo/Continental Siege Machine version of this? (It's pretty much there I think, but for fluff, unless the mechanics allow for deployable PDCs.)
Do the mechanics allow for deployable PDCs?
*quick check with current game*
Not really, no. You can put one in a mothership of sufficient bay size but task forces with PDCs can't be given orders.
*unless*
Still no, even with making an Order Template as a work-around.
