I used my money(kreds) to buy 'elite' and some cards... In conclusion, it is useless. Energy system is annoying. I won't use my money to fill enegy anymore. I give up!!!
Very good game....
I finally finished hardcore mode yesterday... many times I died and restarted...
Continuous weapon upgrade(in smithy) is important.
For friends, sheriff with auto shotgun is best... Knock back skill is very useful.
