I've been trying for hours, and I still can't do it. Part of the problem is the wrong map links in DeZpe's list (v3.2). All M6H map are linked to M3M instead. But it looks like his older version (v2.1) Uses the correct link.
I absolutely hate the G5 upgrade structure. Not fun in the slightest. But it's a necessary evil that I must inflict on myself if I am to make progress in various upgrades.
Looks like I'll just have to settle for medium security settlements for now.
EDIT: CIF, by itself, isn't very useful without Exquisite Focus Crystal (EFC). I've flown 1000+ missions, but I have yet to see a mission that offers EFC as a reward. Is there a trick to finding them?
This is the correct map for the four known M6H's ...
... and my tried and tested, trusted, Truesilver's Top Tip, method is as follows ...
A. 4 pips to Eng, 2 to Sys. Start with the data point at the bottom right (like, south east) position. Scan without trespass.
B. Now drive quickly to the data point by the huge 'radar observatory thing' at the bottom left position (DJA's starting point). There is time pressure here but no trespass. If you trespass just edge back out. Keep trying until you have both - you'll get faster and this puts all the time pressure at the start of the run.
C. Now drive as fast as possible straight north as per DJA's map. Don't get airborne, just get through to the other side, cancelling the trespass.
D. Scan the next two points without trespass as per DJA's map. There is some time pressure again now but not as bad as between A and B.
E. Don't go in for the central point as per DJA's map. Instead go and do the one on the far right (east) position, because it's far less 'fiddly'. You'll trespass a lot but you won't get wanted because ...
F. After scanning this point race directly south, (close to where you started), cancelling the trespass.
G. Now turn around and, with all the time in the world, put 4 pips to Sys, go in and find the final central point, get destroyed if necessary / if you wish.
My route as above is not as quick or elegant as DJA's but
it just works.
I hope this helps!
