What If Disasters Sun Disappears: What Happens and How to Survive

Quick answer

The Sun Disappears round is a slow freeze: the sun dims and stutters, the sky goes black at midday, the power grid collapses and the map ices over while cold exposure drains your health outside. You survive it by getting into an enclosed indoor spot the moment the sun starts to dim and staying there until the round ends.

• The round card is your warning - 'What if the sun disappeared?' means a cold round before anything happens
• Health drains while you are exposed; the game prompts 'Find somewhere warm' and later 'Stay warm'
• The recorded survivors picked one enclosed room and held it through every stage, all the way to an explicit 'Well, we survived'

What happens during the Sun Disappears round

Once the card is up, you already know the hazard family: the players in the recorded run sized it up before the sun moved at all - 'it's going to be a cold one.' From there the round escalates in stages, from a dimming sun to a frozen world. Here is how that run played out:

Mechanic flow

1. 1

   The sun dims

   Sunlight flickers and stutters, then the sky turns dark with stars visible in the middle of the day. Treat this as your starting signal.

2. 2

   Find somewhere warm

   The game tells you to find warmth, and health starts draining from players still outside - the recorded player lost two health with the prompt active.

3. 3

   The grid degrades

   The power grid readout falls to only 43% remaining, frost spreads over the streets and whole cities go dark.

4. 4

   Snow and cracking walls

   Snow falls out of the black sky and frozen walls start to crack.

5. 5

   The ocean freezes

   The ocean freezes solid and the waves stop moving.

6. 6

   The grid fails

   Only backup generators are still humming, the on-screen guidance updates to 'Stay warm down low', and the temperature readout keeps getting worse.

7. 7

   A frozen Earth

   The round closes with 'Earth is a frozen dirt road' and the line 'without sun, the cold is here forever.'

The ending is as much epilogue as warning: after the grid dies and the cold settles in, the round resolves - and the players who had stayed sheltered the whole time were still standing.

Watch the recorded round from its announcement:

How to survive it

The route the recorded survivors used is deliberately unheroic. The moment the sun flickered and stars appeared at midday, they followed the 'Find somewhere warm' prompt into an enclosed indoor spot, and they never left it. That single decision carried them through the blackout, the snow and the deep freeze, all the way to the round's own confirmation: 'Well, we survived.'

Checklist

• Read the round card

  Seeing 'What if the sun disappeared?' means a cold round before the sun has dimmed at all, so pick out your shelter early.

• Move at the first flicker

  When the sunlight stutters and stars appear at midday, head straight for shelter instead of exploring the darkening map.

• Get to an enclosed indoor spot

  Follow the 'Find somewhere warm' prompt fully inside. In a similar freeze round in the same game, any enclosed room did the job - the players just had to stay in it.

• Stay put for the whole round

  Hold that room through the grid collapse, the snow and the freeze. Going outside to look around is exactly what starts health loss.

• Watch the prompts, not the sky

  'Stay warm' and later 'Stay warm down low' are the game restating the same rule: keep sheltering until the round resolves.

What going outside costs you

Cold exposure is the damage source. With the 'Find somewhere warm' prompt active, the recorded player lost two health simply from being out in the open, and the game keeps restating the fix as things worsen - first 'Stay warm', then 'Stay warm down low' when the grid finally fails.

A second, separately recorded freeze round in the same game shows how strictly the game enforces this. Stepping outside there brought up a 'no atmosphere' warning under a black sky, a -30°C readout, and health started draining immediately - 'if you go out here... you start to lose some health.' That round is not named on screen, but it matches the Sun Disappears pattern exactly: outside is where health goes, and the enclosed room is where you stop losing it.

The Sun Disappears round rewards one early decision over any late heroics: get inside fast, stay inside, and let 'Earth is a frozen dirt road' play out around you.
