let me be the first to say this then: canonical source, reference, or implication within the main canon or soft canon (ie, a quote or even a passing mention). otherwise, GIVE US VENATOR STAR DESTROYERZ AND VADER SUITS!!!!!!!
That doesn't count. I'm talking about alien ships. Preferably enemies.
I know . It had to be said tho! Imagine if the Iconians had flying ships (they don't in game) would be a nice tie in to old fashioned human beliefs aliens had flying saucers as if to imply Iconians used to visit earth!
Walkers are pinched from WOTW and the Elachi seem to be from XCOM.
Bit like the Tholian Carriers seem to be a pinched design from the original Blakes7 Liberator.
They do seem to pinch alot of stuff lol.
