Funnel Runners Acid Storm — Weather Event Guide
Acid Storm and acid rain in Funnel Runners. Patch 0.34.23 reduced frequency on Training and Normal; patch 0.34.28 removed Acid Rain from Training Mode entirely.
Corrosive Mid-Run Weather
Acid Storm is part of the fifteen weather variations Supernova Studios ships in the approximately 1 year Early Access launch biome. Unlike a pure tornado touchdown, acid rain punishes players who stay exposed in the open — shrinking safe loot corridors and forcing squads back toward cover while the twenty-minute clock keeps ticking.
Launch-Week Balance Changes
Launch-week feedback flagged corrosive weather as too punishing for onboarding. Patch 0.34.19 shortened Acid Storm duration. Patch 0.34.23 reduced acid rain frequency on Training and Normal difficulties and buffed the Umbrella gadget with a smaller inventory footprint and extended grace period when leaving cover. Patch 0.34.28 removed Acid Rain from Training Mode entirely — use Training to learn route planning without corrosive pressure. Track all updates on our patch notes page.
Survival Tactics
- Pause outdoor loot chains when acid rain begins — finish indoor searches first
- Equip the Umbrella gadget for brief open-street crossings after patch 0.34.23 unlock timing
- Van anchor broadcasts exposure warnings on CB Radio or walkie-talkie
- Do not cross parking lots or parks while carrying fuel cans or tire irons
- Pair with hazard awareness — downed power lines block alternate routes
Where Acid Storm Fits in Weather Rotation
Acid Storm appears in the mid phase alongside hail and fire spread on our tornado intensity ladder. It is one reason launch reviews praise dynamic weather — and why Supernova Studios tuned it across three launch-week patches. Future biomes on the roadmap may introduce region-specific corrosive events.

How do you survive Acid Storm?
Take cover inside intact buildings, use the Umbrella gadget (smaller inventory after patch 0.34.23), communicate exposure timers on voice chat, and avoid crossing open blocks while carrying critical van repair parts.
Is Acid Storm tied to tornado intensity?
Acid Storm appears during mid-run weather escalation alongside hail, fire, and lightning. It stacks with the broader difficulty curve documented on our tornadoes page.
