Norma, just don't buy upgrades. they have to be manually purchased now. you have to have enough production to reach 75 gambling dens without upgrading any buildings. Purchasing infrastructure is fine though
Or more specifically: 1-999 exp focus on factory/industrial zone/roads. 1000-9999 exp focus on bank/commercial zone/electricity grid. 10000+ exp focus on gambling den/residential zone/public transport.
all you need is kick speed, damage, HP, HP regen, acceleration, top speed. kicking is more effective since it doesn't have to reload and gets really fast. even if you choose the shooting path you will end up face-to-face kicking most of the time anyway.
I died on wave 53 on my run after killing the boss. All of my stats were reduced to one, all of the spirit upgrades all say they cost 1000 and the armor icon under the merchant is rapidly changing armor pictures
