Hi, I'm WhiteDragon25! While I don't have the technical expertise to actually create a mod, I do have a wealth of ideas and concepts for one. You can see my mod ideas here on my profile blog, where I talk about them in detail.
Tiberian Essence's Devil's Tongue is another favorite of mine from that mod - Carnius managed to give the Subterranean Flame Tank a makeover that is both functional and stylish. The Subterranean Flame Tank is a really difficult concept to get to work, since there is so little room to manuever with its basic design; but, somehow, Carnius managed to get it to work.
It's design so appeals to me that, were I to actually get around to starting that mod project I've been wanting to do, this unit feels like a perfect choice for a Black Hand vehicle.
(In this theoretical mod conception of mine, one of the Black Hand's subfaction themes, along with its excessive pyromania, would be reviving subterranean tech... perhaps I should start a blog series talking about it...)
