Some interesting feature from scrapped version of the game

[Salt The Fries]

I remember reading somewhere, either on IGN or Gamespot in their preview, that marines from your squad can be grabbed and cocooned, in order to impregnate. You could go to rescue them before the facehugger would impregnate your team-mate. How'd you think, will it be included in this version of the game? It's pretty much interesting feature, to be honest.

Are all the marines chipped with tracking devices?  In Aliens only Newt has one and that's the only reason she can be found.

There would be to many hosts, and thus, too hard to find a single marine.
