Campaign mode cheat. You have to edit the "00000x.cpg" file in the "aos" directory, where "x" represents the specific campaign number. Find the "main.oob" file with a list of ships and select a ship, then place that number in the first column of the 00000x.cpg file. The second to last series of numbers in the column is crew rating, from 0 (best) to 4 (worst).
