What is upgrading How do you upgrade How do you get your hire value up to the billion mark? How do I get more orange gems? These are all answers I can't find. Someone please help....
Upgrading is raising your stats by adding crew, upgrading crew, or replacing your crew with more expensive crew. These "orange gems" you're referring to see probably extra credits or EC's. you have a 2% chance of getting one on every successful job completion. Fails will not give that 2% chance. You can also buy them from the nurse if you go to "store" next to "tutors" and then click on the nurse in the corner.
You can raise your higher value by upgrading. Higher stats will increase your chance of being hired. Being hired raises your higher value.
