@insane_shadowblade85: Yeah, they don't really explain anything. It is /s to talk to the squad and /os to talk to the outfit. Ctrl+tab cycles between chat windows and if you are in the outfit or squad tab, hitting enter will fill in the proper slash command.
@Funkydupe: I kept looking at the armor upgrades and wondering if that was the case. That's unfortunate though.
I spend too much time trying to figure out what is actually worth spending CP on. I was saving up for the last rank of repair but decided to get my shotty fully accessorized instead. Figure the more enemies I kill the more CP I earn, that kill streak bonus is pretty crazy.
