Here's my save for TP Industries Arms Race. Load & get into the plane. Do the mission & achievement will pop once complete. A Lot of Cheddar also pops upon loading. All character have a lot of cash & all skills maxed. Make sure to replace your ID's.
This worked like a charm. I missed this achievement with my original play through and this is a missable achievement. Excellent save! +rep!
it still worked though,THANKS,that was my last needed SP achievement now i have 6 online achievements left it still worked though,THANKS,that was my last needed SP achievement now i have 6 online achievements left
