I was looking at some of the upgrades, and many of them are intuitive such as for the core classes. But others aren't as intuitive, such as the APCR round for the tank and the Wingman upgrade for the planes. It would be less of an issue if you can unlock all of the upgrades, but you select the path that works best with you and the other routes are permanently locked (which is good otherwise you'd be too OP).
Some other upgrades you wonder if it'll completely replace certain weapons. For instance, the bomber plane has an 8x bomb upgrade followed by the 2x bigger bomb upgrade. That made me wonder if the bigger bombs would replace the 8x bombs, or the #1 gun weapon - or else where would it go, a new #5 key?
IMHO, some but not most upgrades should have some info.
This is a quality of life improvement request to prevent any sort of regret of upgrade selections.
Nice idea 🙂.
