Zero-K v1.7.11.4 Tweaks and AI Fix

The AI turned out to be a bit too keen to use the new Conjurer area cloak ability. Here is a quick fix for that, along with some other tweaks.
  • Fixed AI opponents always using Conjurer area cloak and excessively draining their own energy.
  • Fixed a bug where Conjurers would use their area cloak decloak range when using personal cloak under a certain set of conditions.
  • Increased Conjurer area cloak decloak range 128 -> 192 (same as their area cloaker radius).
  • Ravens dive slightly lower.
  • Increased the effect of impulse weapons on planes (not gunships) by 10%.
  • Improved the rearm pad code and added it to the priority system.
  • Hacksaw turns 25% faster and its missiles are better at homing.
  • Fixed Knight attack-move behaviour.
  • Fixed some issues caused by Phantom trying to shoot and kite at the same time.
  • Skirmishing units stay slightly further away from retreating targets with significantly less speed than them.
  • Updated Constable description.

Zero-K v1.7.11.0 - Balance and Quick Modding

This is a balance update, primarily regarding Emissary and Cloakbots, and also includes some vital fixes. There is now a quick modding system that can be used to test out balance, or perhaps just to create wacky game modes. The current position of Cloakbots in the meta made them primes target for some !Fun! buffs.

Quick Modding

Many balance suggestions are expressed on the forum with no easy means of testing. To address this, there is a new setting during game setup, under Advanced Options, that can be used to change almost any aspect of the game, no rebuilding or rehosting required. Check out the wiki page to see how to make faster Glaives and long-ranged Bandits.


  • Jam radius: 256 -> 192
  • Can area cloak with 192 radius and 8 energy drain.

  • Range: 280 -> 350 (to see if the game breaks).

  • Cost 110 -> 100
  • Range 840 -> 860
  • Projectile speed increased 3.8%.

  • Damage: 100 -> 95 (Glaive is the only small unit affected by this change).

  • Speed: 2.5 -> 2.6
  • Sight: 350 -> 280
  • Damage: 36 -> 45

  • Cost 300 -> 285

  • Speed: 2.7 -> 2.4 (Impaler 2.25, Lance 2.2, Tremor 2.25)
  • Range 1180: -> 1120
  • AoE: 96 -> 84
  • Projectile velocity reduced by 4.5%
  • Added overkill prevention vs. static targets.

  • Buildpower: 4 -> 5

  • Sight range: 660 -> 900 (very few units have more than 600 LoS).
  • Laser range: 820 -> 850

  • Disarm missile tracks.

  • Health: 2200 -> 1700

  • Range: 480 -> 490


  • Made the build height display (Alt+Scrollwheel) show the water level.
  • Fixed units sometimes skirmishing cloaked units.
  • Fixed Dgun commander aiming.
  • Fixed an exploit that allowed a player to crash the game (exploited around the 11th).
  • Fixed Scorpion aimpos, allowing many units to hit it reliably again.
  • Fixed the commander window closing itself randomly.
  • Fixed slowbeam target selection.
  • Fixed wade effects.
  • Fixed extended Raven usage spamming the minimap with dots.
  • Minor performance improvements.

Zero-K v1.7.10.0 - Story and Fixes

We return from a bit of a break in development with a campaign update and an experimental performance improvement.

The old campaign mission text, while serviceable, lacked much in the way or narrative or lore. ThornEel has replaced all the text with something much more evocative.

The performance improvement comes from tweaking the frequency of weapon aiming, a parameter that initially set early 2018. Visually, the change should be barely noticeable, however it is likely to impact balance. Benchmarks indicate that this tweak will result in the best performance seen since at least 2017, if not earlier.

Behaviour Fixes

  • Fixed the broken Starlight on planet Cipher.
  • Configured weapon aiming for a significant boost to game performance.
  • Fixed Kodachi being too eager to become a wreck.
  • Fixed firing at buried or otherwise obscured Berthas by raising its aimpoint.
  • Fix a bug related to Gunships climbing steep cliffs.

Other Fixes

  • Fixed the most common cause of lag when selecting units as a spectator.
  • Fixed Area Mex causing duplicate commands in some cases.
  • Fixed a bug with queuing construction orders for incomplete Strider Hubs.
  • Updated Russian translations.
  • Fixes for depth-of-field.
  • Fixed shadows and shaders for some old graphics cards.
  • Fixed wading unit wakes.
  • Fixed economy module description.
  • Swapped some ally teamcolours for better distinguishability in small games.
  • Puppy Goo now updates wreck tooltips correctly.
