What was the circle on the right [in the early thumbnails]? That was some kind of broadcast or sensor thing that would raise up?

Yeah, it's a long-range scanner for picking up data, maybe some data that you shouldn't actually acquire, but data nonetheless.

So originally we were thinking it would be something that was recessed and then when you needed it, it would raise up from there.

Deploys, yeah, exactly. Just so it doesn't get in the way too much.
