Five things we fixed

If you loved classic browser space strategy but no longer have the nights for it, this is for you. We kept the heart of the genre and removed the reasons people quit.

Money buys looks, not power

How it usually goes

Premium currencies, speed-ups and resources for sale. The biggest wallet wins.

In Sunsfall

Only cosmetics and convenience are for sale. No premium currency, no speed-ups, no resources.

Sleep is not a weakness

How it usually goes

Night raids, alarm clocks, and a lost fleet because you went to bed.

In Sunsfall

Quiet Hours: a daily 7-hour window when no one can attack or spy on you, plus a push alert for every incoming attack.

Everyone starts together

How it usually goes

Veterans with years of head start farm newcomers for days.

In Sunsfall

Every season starts from zero. Newcomer protection and a catch-up bonus keep late arrivals in the race.

Worlds that stay alive

How it usually goes

Universes shrink to a handful of players, then get merged.

In Sunsfall

Eight-week seasons instead of mergers. Clearly labelled NPC factions keep quiet sectors busy, and a new universe only opens when the last one is full.

Depth without clutter

How it usually goes

Layer upon layer: a dozen planets to babysit, extra tech trees, endless expedition grinding.

In Sunsfall

At most 8 planets, 3 resources plus energy, and a daily expedition limit. Real decisions, no spreadsheets or browser scripts.

Still here: raiding, espionage, debris fields, real-time fleets on a coordinate map, alliances and leaderboards.

Eight weeks. One dying star.

Every season is played around Vesper, a red giant on the edge of collapse. When it falls, the season ends, the winners enter the Hall of Fame, and a new system begins.

  1. Weeks 1–2

    Dawn

    Expand, mine and found your first colonies. Newcomer protection covers everyone.

  2. Weeks 3–5

    Noon

    The main war. Alliances form, fleets clash, and joint attacks hit hard.

  3. Weeks 6–7

    Dusk

    The Relic Beacons awaken and Vesper grows unstable. Inner orbits produce less every week, so empires have to move.

  4. Week 8

    Sunsfall

    The final 72 hours: beacon points count double and Quiet Hours shrink to 3 hours. The season closes at a fixed time.

What carries over

Titles, cosmetics and your season stats. Never resources, ships or research: next season, everyone starts from zero again.

All numbers are current design values and may be tuned before launch.

A day in Sunsfall takes 15 to 30 minutes

Fleets fly in real time while you get on with your day. Two or three short check-ins keep you competitive.

Quiet Hours 23:00–06:00Your check-ins
  1. Morning5 min

    Read your reports, fill the build and research queues, send out a raid.

  2. During the day5 min

    A push alert says your fleet is back. Send the next mission from your phone.

  3. Evening10–20 min

    Coordinate with your alliance, launch the big attack, then let Quiet Hours take over.

Quiet Hours

Pick a 7-hour window, say 23:00 to 06:00. During it, your planets can't be attacked or spied on. The price is fair: you can't attack or spy either. You can change the window once a week, with a 24-hour delay, so nobody can use it as a tactical shield.

  • Patrol

    Your fleet circles your home system for 1 to 12 hours, can't be attacked and comes home on its own.

  • Bunker

    Keeps 10–40% of your stock out of raiders' reach.

  • Alerts

    Attacks on players take at least 20 minutes to arrive. You get a push alert, email or Discord message as soon as one is spotted.

Money buys looks. Never power.

Be there when the first season starts

Sunsfall launches only when it's finished, and there are no pre-orders. Until then, we share development news on our Facebook page, and that is where we'll announce pre-registration for season 1 and launch day.

Sunsfall is still in development. We'll announce on our Facebook page when pre-registration for season 1 opens and when the game launches.
