Update 1.5

Relics, uranium and fission, the Dyson Sphere endgame, multiple launch pads and 10 new achievements.

Relics

Rare relic blocks now spawn deep underground (1,500m+), in asteroids and on comets. Break them to collect relic fragments.

  • 8 collections to complete, 5 pieces each: Fossils, Gems, Anomalies, Mining Tools, Void Crystals, Tech Cores, Energy Cells and Extinct Species.

  • Every piece grants a permanent bonus: faster smelting, better ore drops, cheaper launches, longer events and more.

  • Complete a full set to bank a stacking permanent bonus that survives prestige, then the set resets so you can hunt it again.

Uranium & Fission

  • Uranium asteroids appear on the orbit map. Mine them for Uranium-235 and Uranium-238.

  • New machine: the Zentrifuge, the only drill able to mine uranium asteroids.

  • New research: Uranium Mining unlocks the Uranium Rod recipe at the Plasma Forge.

  • New research: the Fission Furnace, the most powerful smelter in the game, burning 1 Uranium Rod every 5 minutes as fuel.

Dyson Sphere

The new endgame goal. Many players asked for a clear objective, and this is it.

  • New research branch, then manufacture four components: Solar Panels and Energy Relays at the Nanofabricator, Structural Frames and Thermal Shielding at the Fission Furnace.

  • Load components into your rocket and launch them toward the sun. The sphere is built ring by ring across 1,080 segments, tracked live on the orbit map.

  • Dyson Sphere progress survives prestige. A victory screen appears once the sphere is complete.

Multiple Launch Pads

New research: Launch Nexus. Buy up to 10 launch pads and run that many rockets in parallel, each with its own cargo and target.

New Achievements

10 new Steam achievements covering the new content, from your first relic fragment to a full fleet of 10 rockets in flight at once.

Balance

  • Mastery: one more upgrade per prestige cycle for every prestige you have done.

  • Machine Blast now applies to every non-fullwidth machine instead of only the Jackhammer.

Bug Fixes

  • Fixed the game secretly running behind the main menu after quitting a save.

  • Rockets no longer travel while the game is closed.

  • Fixed lag spikes on saves with many mines.

  • Many automation, tooltip and localization fixes.

Feedback welcome!
