How AstroLurch works. Numbers below are the rules in the game. A universe can multiply economy, research, or fleet speed on top of them.

Getting started

  1. Create an account and choose a universe. Each universe is its own galaxy.
  2. Raise the Metal Mine and the Solar Plant so the mines have power.
  3. Follow the Tutorial. Each step pays its reward once when you collect it.

New accounts have beginner protection. The default length is 7 days. While it lasts, other players cannot attack you. Sending an Attack or a Missile Attack ends your own protection for good. You also cannot attack a player who is still protected.

Resources

Planets store Metal, Silicates, and Helium-3. The Power Grid is energy: it is produced and consumed on the planet and is not a cargo resource.

Buildings

Most buildings occupy one field per level. Construction time starts from the building’s base time: base time × level × (time factor^(level / 2)), then the global building-time multiplier. The Robotics Factory and the Atomic Assembler shorten that duration by dividing it by (1 + robotics level) × 2^(Atomic Assembler level). Each Atomic Assembler level halves the remaining construction time.

The Robotics Factory also opens extra build-queue slots at higher levels.

Research

Research needs a Research Lab. Duration is base time × level × (time factor^(level / 2)) × global multiplier, then reduced by the lab. Each lab level multiplies the time by (1 − lab reduction). The default reduction is 5% per lab level. Computer Technology networks your highest labs in that universe: the number of labs that count is the Computer Technology level, and level 0 uses only the current planet’s lab.

Fleet

Distance between two coordinates:

Travel time is at least 60 seconds: distance × 3,000 / effective speed + 10. Effective speed is the slowest ship in the fleet, including drive research, times the throttle. Throttle runs from 10% to 100%. Fuel is Helium-3. A universe fleet speed above 1 divides the time and still keeps the 60-second floor. Ships with speed 0, including Solar Satellites, stay on the planet.

Espionage

An Espionage mission needs Espionage Probes. Probes can scan planets. They cannot scan moons. The report arrives in Messages. Probes can be destroyed.

Intel level = Espionage Technology + 2 × Advanced Espionage − Espionage Deflection + floor(√probes).

Detection chance, clamped from 0 to 100, is 2 × probes + 8 × Espionage Deflection − 5 × Advanced Espionage. A successful detection destroys the probes.

Attacks and combat

Send the Attack mission. A planet with no ships and no defences is looted at once and the fleet returns. A defended planet opens a combat that continues one round per combat tick until one side is gone. After 50 rounds the side with more remaining firepower wins.

Alliances

Alliances belong to one universe. Found one or apply to join. An application stays pending until the alliance accepts it. Pending applicants are not members. Fleets heading to your planets are listed on the Fleet page with their mission and ship counts. Alliance members and buddies are marked friendly there.

Lurchium

Lurchium is one balance on the account. The same amount is available in every universe you play. Planets, buildings, research, ships, fleets, alliances, and rankings stay separate per universe.

You can earn Lurchium from expeditions, missions, the tutorial (including a one-time 100 Lurchium graduation), email verification, and referrals. Spend it on officers under Premium and on the cosmetic shop. When card payments are configured, packages are listed in the shop.

Universes

Each universe has its own planets, buildings, research, ships, fleets, alliances, and rankings, and it can have its own economy, research, shipyard, and fleet speeds. Switch universes from the Universes page. Lurchium is the shared account balance.

Achievements

Achievements record what you have built, researched, and done. Each tier pays Lurchium once, onto the same account balance you use in every universe. The badge for that tier is yours on the account as well.

Most achievements count inside the universe you are playing. Account achievements add up across universes. Secret achievements stay hidden until you unlock them. Until then the page only tells you how many secret achievements remain.

You can show up to six unlocked badges on your public profile. Shop badges stay separate. If a universe turns achievements off, badges you already chose still appear on profiles.

Tutorial

Phases open in order. Inside a phase, collect the current step before the next one counts. A locked phase still lists its steps in grey, with a Locked label and no action buttons. Collect each reward once. Resources go to the current planet. Lurchium goes to the account.
