So should I start over again since as I said subtracting points from an upgrade ends up with less after for instance I had enough to get the solar ATV module but I took the points back and had only 300 or so can't give the exact number. Point is it seems when it comes to the upgrades you need to be sure what you want apparently other wise this happens. Are you sure you get no points for 0 levle signals? That's what you have to start off wiht since it takes 50 points to go to level 1.
It's something the game teaches you in the tutorial. You don't get anything for level 0, and you need to process at least to the first level. It's difficult to recommend what to start with, because everyone prefers starting in their own way, but I definitely recommend the stuff that'll help conserve money first, then use the money on upgrades when you can.
