Cozy Radiation Cleaner Overhaul Adds Open World, Vehicles, and Tornadoes

Cozy Radiation Cleaner has received what developer SilverSet Studios describes as its biggest update to date, fundamentally changing how the game is experienced. The shift from objective-to-objective progression toward open-world exploration is the central change — players can now move through contaminated environments at their own pace, investigating abandoned locations and hidden points of interest without a prescribed path.

What changed

• Open world: The game's structure has been rebuilt around free exploration of a significantly larger environment.
• Vehicles: Transportation has been added, intended to help players cross the expanded map more efficiently.
• Tornadoes: A new environmental hazard that can threaten players while they navigate contaminated regions.
• Collection system: Items are now scattered throughout the world, some in plain sight, others requiring careful off-path exploration to find.
• Reworked and expanded maps: Environments have been redesigned and broadened in scope.

The update also emphasizes discovery as a reward in itself — the world, per the announcement, contains more environmental details for players who stray from main routes.

Note: the source text ends mid-sentence on the map rework description, so the full scope of environmental changes is not entirely documented here.

For returning players especially, this amounts to a meaningfully different game than what was originally released.
