Hard at first, but easy if u have a little money
there are some bugs or something that ruins the game yet. SPOILER ALERT!!!! if you want to play the game that it is meant to be played, read this. This can hints and guide for you.
Here is a "bug i found"
Unlimited Energy: Get metal heart. Every attack refills the energy bar. So I never have to go sleep.
Crafting: it is too expensive because you success rate is too low. i spent so much money on it and it keeps failing even though it is suppose to have a 30% success rate. Much rather spend it on Buffout, Psycho, or Jet. The price cant even begin to compare. I can just take the 10k and buy Buffout and Jet, and Antitox. One hit kill everything. No need to mutate to higher levels
The beginning is brutal. The grinding doesnt give exp but if you go and get energy, your hungry meter goes up and i spent most of the time buying food. And the employees keep dying. Really hard to get money early on.
And what does metabolism do. As far as i am concerned it does nothing.
I dont want to spam too much. Ppl are welcome to PM me for more tips.
