So I thought it would be cool if there was an upgrade where traitorous/detective could spawn with an extra credit. So instead of T's starting at 2 they would start with 3, and instead of D's starting with 1, they would start with 2.
Its not hard to get credits as it is. You can practically get 3/4 of necessary items by rounds end. If you do search other T bodies and Detectives you can even find up to 5 credits. -1
-1 traitors can get plenty of credits from killing detectives and innocents. Detectives also get plenty of credits from killing traitors. I usually end up with more credits than I know what to do with towards the end of a round.
