GAME DEV STORY

has to be on a single character. would recommend doing on a special character, like Mister X (as an example).

level up the character using research points up until lvl 5 (each role will cost different amounts of research points per lvl). use career change manual to switch roles (purchased off salesman).

the roles are;
coder, writer, designer, sound engineer, director (requires lvl 5 coder & writer), producer (requires lvl 5 designer & sound engineer), hardware engineer (requires lvl 5 director & producer), and hacker (requires lvl 5 hardware engineer)

once you have reached lvl 5 on all careers on a single character the achievement will unlock.

recommendation: do the 4 basic roles first, and then follow with the director and producer roles as this will affect your stat's the least (when switching, depending on totals, stat's can be taken away, so switching from a second tier career back to a basic may result in more stats being removed).
