How to backtrack to ID A.Fielding?

[bulletshowerr]

I have missed that ID, and since reload any mission will overwrite my progression, i am looking for best way to collect all missing ID. I am now at the end of Mission 12 where is no Alien. I have looked walkthrough how to get the ID from A.Fielding but i cant find that place back. https://www.youtube.com/watch?v=hT9UppquX_U#t=01m01s

Will i ever come back to that place where the ID is in the next few missions?

Any help or suggestion to get there from Mission 12?

Where you're at in the game you will have no choice but to continue with the path it takes you on, but come mission 15 you will get a chance for backtracking (pick up the access tuner upgrade first if you want to access all areas).

From the 10 missing ID i was able to recover 7 of them at the end of Mission 12. C.McCormack (somewhere in san cristobol med facility) and A.Sawers (same area) wasnt possible for me since the main door need special ion torch.

It is pretty weird to come back at places where i was very scared because the Xeno was there or nuts people, now most of them is really empty, sometimes there are some androids (simply outrun them) and once i walk into 3 humans (1 was sitting at the floor) which looks friendly until one of them get mad and start shooting at me.

Well, guess it will be Mission 15 then.

Update: I can confirm i get the A.Fielding ID tag by loading Mission 2 and then using previous savegame i was back at where i am actually in the game (mission 16) and the ID stay in inventory. Just dont use any savepoints and go directly to your missing ID and after that immediality quit the mission and use previous savegame. (current savegame will bring you to the start from the mission you selected). Just to be sure i use savepoint again in mission 16 so i have double same savepoints at once.

After that i also have grabbed the C.McCormick ID in mission 6 and repeat as above. Now i have all missing ID.
