People who hate on the energy system just don't understand that the game would be fricking boring because you would be able to get everything in one day, the have would't have a purpuse if it didn't have the energy system
the creators just keep making things more expensive. the creators of TDP are obligating us tu buy stuff with real money
for example the M16 back in the day it was woth only 10000 coins no cash now 10 dude... really? this game will not last very longer if they don't lower the prices.
Increased zombie speed was a bug and it has been fixed now.
