At the start of the game, you can't do mutch more then replace old parts with new one you buy at the market. It can be tempting to sell them but keep them to fix them on stations as broken part have a very low resale value.

As you gain reputation, you gain acces to buy stations. Buy them as soon as you can to fix part collect on meck you fix.

The time you spend on a job have no effect. Only exception are the job with a time limit but it have a small effect on reputation. So, if you have the station to fix a damage part, go fix it and put it back.

When you take a job, you have the main request and some optional request. Doing optional request give you more money.

99% of the time, when you have a request to change a part for a new one, you can easily find one on the same meck. It don't have to be at 100% but only have the green arow tag on it identifying it as new. You can also trade your old parts for more fresh part at the same time.

At your main console, you can buy actions of the 3 company. When you have some sleaping money, buy some actions. You can have as many action in a company as your reputation. Like the parts, the cost of the actions will move over time. Try to look them ofthen and buy when they are low. Doing a job when you have some action of the company will give an extra of 10% of the avtual value of the company. It may look small but after a few jobs, they will pay themselves. But always keep in your pocket around the same amount of money as a job offer to be safe.

Buy part only if you absolutely have to. Building a stock of part is not essential as you don't have a delivery time to whait for them.

If you need money to finish a job, you can sale some of your actions. Once again, look the market price and try to sell actinos at a hier price then what you paid.

If you still need more, you can take a loan. You can set the amount and the rate you want to pay. It will take a part of your income on all your jobs untill they are paid so try to not count to mutch on them.

As I was playing, I try a silly thing. I accepted a job and I completely dismantled the Meck then I returned it without anything on it. At that time, I had about 20,000 and 20 to 25 reputation in all 3 legit companie before returning the Meck and I got a penalty in the seven figures and lost 1 reputatuon on the crime organisation as it was them I try this. I was Game-Over but I received the possibility that the companies contribute to give me a second chance. It is a one time chance and normally, the amount the player receives at that time is 5,000 but I ended up with almost 3,000,000! If you want, you can try but I don't know if it will work for you! So don't complain if you try and it don't work.

I still have to do a bit of research and progres in the game as I'm only at the point where I can buy my first scram meck. If you want to help, I will greately appreciate il.
