The Crust 1.0 Global Events Guide: Solar Flares & Defense

The three Global Events at a glance:

Event	Trigger	What it does	Documented counter
Solar Flare	Random, no published schedule	Damages surface buildings and colonists; boosted solar output is explicitly uncertain	Batteries underground are immune since Hotfix 1.0.9
Epidemics	Unsanitary, chaotic colony	Lowers mood and work efficiency; worst cases bring injury or death	Showers and toilets in rooms, positive medicine balance
Meteorites	Random, one rock or a shower	Debris and resources early, base damage as empty space shrinks	Anti-Meteorite Laser Cannon: one Energy Cell per shot, needs recharge, partial coverage

Solar Flare

The 1.0 announcement describes Solar Flare as a randomly occurring event with two possible outcomes, both stated by the developer:

“This event occurs randomly and can either trigger increased power output from your solar panels (but that’s not certain =)) or damage your buildings and the colonists working at their posts on the surface. But your brave scientists will come up with an elegant defense against this event too.”

Three core characteristics define the base event:

1. Solar Flare fires randomly. There is no scheduling published.
2. The benefit (boosted solar output) is not guaranteed. The parenthetical “(but that’s not certain =))” is the developer’s hedge. Players cannot plan around it.
3. The cost (surface damage) hits buildings and colonists.

Underground Battery Immunity (Hotfix 1.0.9)

In the launch build, solar flares drained batteries indiscriminately across the colony. As of Hotfix 1.0.9 (released September 15, 2026), the developer reworked the event:

“Reworked the Solar Flare event. Batteries located underground are no longer drained by it.”

This provides a reliable architectural solution: constructing your primary battery reserves underground renders them fully immune to Solar Flare drain, protecting against total power grid collapse.

Epidemics

The 1.0 announcement is unusually direct about Epidemics:

“Epidemics break out when the colony is in chaos and unsanitary conditions. They worsen colonist mood and work efficiency, and in the most neglected situations they can lead to colonist injuries and deaths. This event is easy to avoid by equipping rooms with showers and toilets and by keeping a positive balance of medicine on the base.”

Three actionable facts fall out of that paragraph:

1. Cause: unsanitary conditions and chaos, not bad luck.
2. Effect: lower mood, lower work efficiency; in worst cases, injury or death.
3. Prevention: showers + toilets in colonist rooms, and a positive medicine balance.

The 1.0 announcement introduces a Shower/Toilet module in the same release, and the colonist-management page on this site describes the morale and workforce maths in detail. The Anti-Epidemic defense is therefore a build-toolkit answer, not a tech-tree answer.

Meteorites and the Anti-Meteorite Laser Cannon

Meteorites are the headline defensive event in 1.0. The developer describes them in two places: the Global Events section and a separate “New module” subsection. Quoting the announcement directly:

“Meteorites are one of the new events. They fall one at a time or in a whole shower, and you cannot choose when or where they land. The process is, of course, random, but our programmers have kept quiet about the probability they set ;).”

“While your base is small, most rocks land on empty ground and leave behind debris rich in resources, including rare minerals, so for a while you will be happy about every impact.”

“But over time, the base grows and there is less and less empty space. Before you know it, a meteorite will land exactly where you spent three hours in Planning Mode. We did tell you that production on the Moon is no easy business, didn’t you?”

The 1.0 answer is the Anti-Meteorite Laser Cannon:

“For this stage, there is the Anti-Meteorite Laser Cannon. It shoots down rocks as they approach, but not for free: each shot costs one Energy Cell, after which it needs to recharge. One cannon does not cover the whole base, so decide what to protect first: the reactor or the bar.”

That paragraph names three concrete behaviours:

1. Resource cost per shot: 1 Energy Cell per intercepted rock.
2. Cooldown: the cannon must recharge after each shot.
3. Coverage limit: one cannon does not cover the whole base; coverage is positional.

The announcement does not publish a recharge time, a coverage radius, or a damage number.

Base Readiness Priorities for Global Events

• Stockpile Energy Cells near critical sectors: Because each Anti-Meteorite Laser Cannon interception consumes an Energy Cell before recharging, maintain a dedicated conveyor or storage buffer feeding your defense perimeter.
• Keep medical supplies in positive balance: Epidemics check whether your colony’s medical balance remains positive as population grows; expand medical facilities before accepting new colonist waves.
• Buffer battery capacity for Solar Flares: Because a Solar Flare can either spike or drain your grid, keep reserve accumulator banks connected so nighttime life support and refineries never stall.
