Engine update to Spring 104.0.1-1239

It is time for another engine update. We have recently experienced trouble updating, but, after running some multiplayer tests, this update has a decent chance at success. Due to the time between updates there are more notable changes than usual.
  • Saved games now compress the entire game state, instead of saving only a few key attributes. This vastly improves the accuracy of saved games. Old saves should still work.
  • The bug which caused commands to sometimes disappear in long FFA games has been resolved.
  • A pathfinding bug relating to skipping waypoints was fixed. This improves the pathing of groups of units around corners.
  • A desync related to the game mysteriously misplacing files may be resolved.
  • Various graphics related crashes have been resolved.

Zero-K v1.7.5.0 - New unit: Sparrow

This version contains a few oblique plane nerfs and a simple Raven nerf. The biggest such 'nerf' is a new scout plane, the Sparrow, that can be morphed from a Radar Tower. This new scouting option loosens the Plane Factory's monopoly on effective scouting.

In other news, Scalpel can now kill Mace in two shots and a few campaign missions have been improved.


Added Sparrow, a light scout plane that is morphable from a Radar Tower.
  • Cost 120. Note that it costs 65 when morphed from a Radar Tower.
  • Speed 225
  • Health 400
  • LOS 950

Raven is slightly more expensive
  • Cost 300 -> 320

Scalpel now kills Mace in two shots.
  • Damage 622 -> 660

Blastwing can see further
  • LOS 380 -> 450


  • Added an option to control when wreckages and rocks are highlighted. The options are always, when reclaiming, or when constructors are selected, which is the new default.
  • Improved some depth of field details.


  • Replaced planet Aspiris, the Tank Foundry mission, with a more interesting Tank Foundry mission.
  • Added Sparrow unlock to planet Cygnet, the Sling mission.
  • The patrolling units on Kirdipan, the terraform mission, no longer chase the players units.


  • Fixed some bugs with heathbar LODing.
  • Clamp instead of block off-map commands. These commands should not normally be issuable, but when they are issued it is good to give players feedback.
  • Fixed units set to guard shields or cloakers ignoring custom formation orders.
  • Fixed a performance issue with lobby UI scaling and fullscreen switching.

Zero-K v1.7.4.0 - Fixes and Outlaw Tweak

This version contains a few important fixes, compatibility for an upcoming engine update, and a reduction of the previous Outlaw buff.


  • Outlaw damage 35 -> 30 (was 20 previously) with the same scaling for slow damage (105 -> 90).
  • Paladin manual fire now fires 12 missiles (increased from 10) to match its model.
  • Raven thinks units are thinner than they are, causing it to dive lower and hit more consistently.
  • Welder defaults to hold position.


  • Fixed units failing to reveal themselves if they fire from behind terrain while inside an enemy units LOS range. This primarily makes buried defenses targetable.
  • Fixed units with attack orders not having their attack order overridden by some commands. This mostly affected issuing reclaim orders to fighting Welders.
  • Fixed a case of tactical AI not working for units on hold position.
  • Blocked the ability to give gunships orders off the edge of the map.
  • Zenith now gains XP and can shoot through allied shields.

Depth of Field Fixes

  • Fixed issue where the autofocus would incorrectly weaken when zooming in after a certain point.
  • Fixed colours blending to a mush (unfortunately this means some banding in dark regions, not sure how to fix without ruining the more pronounced circles).
  • Normalized depth calculations to Spring unit distances, so blur power is no longer map-dependent.
  • Fixed projectile lights rendering on top of DoF (this involved changing priority, and this seems like a blunter fix than necessary).
  • Expanded blur radius limits so near-to-camera objects blend more nicely.
  • Made the transition from in-focus to out-of-focus a bit smoother.
