One thing that bugs me about being the Alien Commander is that there isn't a scan ability.
I'd like to propose a new ability for the Gorge because of this. An "Echo" effect. The gorge would enter a room that the commander wants to see, then they would "yell", producing a sort of echo-like effect that shows the commander what is in the room.
I figured this would be similar to that of the Alien vision, in which when the Echo is used, any structures that are in the room would be highlighted and outlined, instead of showing up normally.
This would give the Gorge another ability that would be useful for the Commander, which could encourage team work.
