Will there be new vehicles, like gunships for instance?
Personally I think it's enough with Mantas and Walruses, but if there will be more vehicles then it's fine too.
Besides gunships, what more could there be do you think? And what will these vehicles be called?
If I am not mistaken, the Mantas' and Walruses' names are in reality abbreviations, but I don't remember what right now.
If I were to venture a guess, the gunship would be called Crab. The abbreviation could be as follows; Close Reconnaissance Armored Battlecraft
The Crab would be better armored than the Manta, but comparatively slower, being a gunship and all. Its weapons might still be on par with the Manta though. Maneuverability would be of course different than the Manta since it will be able to hover and fly sideways and backwards.
