some of the mini games don't have rules. the lockpick and hacking are just like in the fallout. i am currently stuck on the scrap metal. no clue why they are not working. I went back and left the batteries in. stupid stupid minigame. with dossimeter you can see which scrap had radiation. you can't otherwise. so game of pure luck. which you will fail cuz irradiated scrap wipes out 4 points towards 15 points to succeed. so far game is not worth buying.
