Rusty is a small robot with a big dream: a quiet retirement spent farming. Players guide him through a cozy agricultural loop—planting, watering, and harvesting crops, then converting the yield into clean biofuel to sell to neighboring machine inhabitants and reinvest in the farm's expansion. A team of helper bots can be deployed and upgraded to automate every task, letting the farm run itself. Rusty's Retirement is designed to sit at the bottom of the screen as an idle companion to other activities, with zoom controls and a Focus Mode that slows crop production for a less demanding experience. A vertical farm layout is also available for side-screen placement. Streamers can invite their community through Twitch integration, letting viewers direct the helper bots via chat commands.
