S+ Tier

Button PresserAutomationThe Button Presser is the most important NPC in Ice Tycoon 2. Without it you are limited to one drop every 15-20 seconds, so this single hire roughly doubles your effective drop rate.

A Tier

FarmerAutomationThe Farmer keeps the raw material pipeline topped up. Hire this NPC after the Button Presser so your freezer is never idle waiting on inputs.ShopkeeperAutomationThe Shopkeeper stands at the output desk and sells processed ice for you, so you do not have to camp the collection terminal. He is removed by the Circle trophy event, so plan around it.
