If you wanna do it legit heres an old vid from my 360 run with my skill-lacking butt. Some parts are sped up for brevity but it shows more or less my path through the game. I'm working on a new vid with the better graphics and a slightly better/easier route for the average player after I get back from vacation.
OR if you wanna take the easy route, see my LASO solution. Save/quit at the end of each mission then load up the non-modded PC version or XB1 version to complete the mission for credit.
