And technically speaking, in the time line of GRFS, 3E Elite wouldb't be Sci-Fi at all, SC agents may very well be using it as a default suit.
If I recall correctly End War & GRFS take place around the same time right ?!
Da**, I think I would welcome a SC Title Spin-Off in the not so distant future
Edit: After reading the pic Jazz posted, it strikes me how close this to be in the game (if ever one is made)
Weapon: seeking bullets already there in GRFS.
Exo-Skeleton: already there in reality, and was there in GRFS 2010 Version.
Camouflage: Predator Effect ?!, someone call Max, he is going to love it, even though it has been done before in MGS4.
Helmet: AR+Tri-Focal Goggles+whatever = totally awesome in concept
Smart Cloth: well we got GRFS Cameo, and Human who can take out tanks with Grenades, I don't think it is impossible LOL
Edit 2: After reading all these, anyone went to play some D-Ops ?!, I know I want to.
