I m progressing on N7 II
. I went from a fail on W9 to an extraction with no WS to one with 3WS !! I m not so far anymore 
I have a "big" problem with cheesing the hack along the escape road where we all start waves (at the far end of the map near LZ)
This should be very easy to cheese as U can start the hack outside of the hacking zone.
But it s the third time i have to go back inside (first 2 i did nt even see that i had to come back inside for at least 1 min
). bug or have I to stay for an instant inside the hack zone ?
I have also been instakilled right at this hacking start spot on W6 by rockets and ... WTF ! Gates were not working right there 
(I have almost learn to take my time with objectives, and last run was not to bad for obj., no freeking device spot yet)
