I've been working on a final batch of T6s recently in an attempt to atone for being gone so long, and this is what I came up with for the Cybran unit. Each unit can activate one -- but only one -- of these abilities at a time. Having more than one of this unit, however, means that each one can have a different ability activated (although they can also, depending on the ability, double the effectiveness of the said ability if they both have it activated).
What in the world? is this a dooms day weapon?
It's for a T6, so...I think "Doomsday weapon" is a pretty good description, yes.
