lol i give u a hint i helped do this a coule of times and its no exploit.....
get a team of 6 prefably all about same lvl so it can work or 3 high lvls and 3 low lvls...
1. goto magog west Hl and start missions
2. first 2 ppl (1high lvl and 1low lvl if applicable) goto first building once phase is compleate than run back to hl
3. next 2 ppl goto next building and so on
4. next 2 ppl goto next building and finish mission
5. repeat ...should send u too exactly same buildings as b4 just different floors....takes about 2-3mins to compleate missions from now on each time giving you about 150k so 20mins is 1.5mill
