Zero-K v1.8.4.4 - Engine Update

Recent engine development focused on a single number - the CPU usage of terrain rendering - and a new version is ready for release. The old renderer was quite expensive when zooming around, even lategame, whereas the new one is barely noticeable. For the best results consider tweaking your map detail settings.

Along with the engine update we have fixed a few issues from v1.8.4.0. The elo options in !proposebattle now work and there is a larger teams matchmaker. Lingering Lobster bugs are gone and Crab has some additional fixes.


  • Map rendering is much faster. This should be especially noticeable on lower-spec computers.
  • Nanoframes no longer decloak. As a side effect terraform construction points are no longer placed far underground.


  • Fixed the minelo and maxelo options in !proposebattle.
  • Split the 2v2 - 4v4 matchmaker queue into 2v2 - 3v3 and 4v4 - 6v6.


  • Fixed Lobster throw bugs and unreliability. The improvements of v1.8.4.0 are now properly live.
  • Hacked around Crab uncurling issues to make the bug less common.
  • Units no longer run away from economic structure AoE if the structure is in a hole.
  • Fixed some map trees having unintentionally low energy values.
  • Added compatibility for some maps that set the energy values and reclaim time of trees too high.

Zero-K v1.8.4.0 - Terraform and Battle Proposals

This is a patch of tweaks and systems. The main balance tweaks are nerfs for Shieldbots and Hovers, while Crab and Lobster have been buffed in the form of fixes. Sea battles are easier to track with much more visible torpedo effects. Bolas is in the campaign and can be found on planet Falloway.

The patch boasts two new systems. The first is a battle proposal system which aims to solve many of the coordination issues involved with hosting a game. The second is a terraform keybinding system to make terraforming easier than ever. To counterbalance it there are some tweaks that make it easier for units to shoot into holes.

Battle Proposals

Sometimes you may want to organise a battle but find the public hosts a bit chaotic and the matchmaker a bit impersonal. To address this there is a new battle proposal system that combines the coordination of a matchmaker and customisation of a room. If there is enough interest we might even write a proper UI.
  • Type '!proposebattle' anywhere in the lobby to propose a battle.
  • Other players can click the text to accept the proposal.
  • When enough players accept the proposal a game is hosted and the other players automatically join.
  • '!proposebattle' can be followed by the parameters minelo, maxelo, minsize and maxsize. For example '!proposebattle maxelo=1600 minsize=6 maxsize=6' would propose a six player game for players with rating (maximum of teams and MM) below 1600.
  • The host of the battle can use commands as usual. '!password' can be used to make the game public and !type' can be used to select different game modes.


  • DPS increased by 2%.

  • Cost 170 -> 175

  • Damage 30 -> 25
  • Slow damage 90 -> 75
  • No longer fires underwater.

  • Speed 48 -> 45
  • Turn rate reduced by 12.5% (still 5% more than pre-Superfluid)

We are leaning into the low-manoeuvrability aspect of Hovercraft now that there is more room at the low end of the scale.
  • Dagger turn rate reduced by 20% (still 28% more than pre-Superfluid)
  • Scalpel turn rate reduced by 20% (still 28% more than pre-Superfluid)
  • Mace turn rate reduced by 6% (still 7% more than pre-Superfluid)

  • Range reduced by 1.4%
  • Reload increased by 1.2%

  • Health 240 -> 260
  • Build Power 4 -> 5

Normalised constructor vision ranges.
  • Crane 380 -> 375
  • Wasp 350 -> 375
  • Mariner 325 -> 375
  • Weaver 380 -> 375
  • Quill 325 -> 300
  • Mason 273 -> 300

Other changes:
  • Lobster now lobs units directly upwards and adds the horizontal velocity over half a second. This prevents Lobster lobbing lobs into itself.
  • Crab no longer stops shooting under heavy fire. It can now fire while curling and uncurling (this was always the case yet nobody seemed to notice).
  • Drones now heal at 10 hp/second after 10 seconds of inactivity.
  • Metal Extractors and Caretakers are a bit taller and units aim at them higher up.
  • Metal Extractors can no longer be built on steep cliffs.


Terraform tends to be more common after interface improvements. Some issues with the current system have been fixed:
  • Most units, including vehicle raiders, can shoot into terraformed holes.
  • Walls that block particular unit types (bots or vehicles depending on height) are more expensive and look more substantial.
  • The area to be terraformed is now marked while constructors spend the base cost of terraform.
  • Unburrying enemy units is feasible with overwhelming buildpower.

The details of the fixes are as follows:
  • Terraform near an enemy is now 20x slower instead of 50x slower. A bug that caused enemies to fully block terraform has been fixed.
  • The angle of terraform supports is now 74 degrees (from 75 degrees).
  • The angle of the outer edge of the terraform supports is limited to 22.5 degrees. This raises the height required to block vehicles.
  • The angle of the inner edge of a subractive terrafom support is limited to 45 degrees. This rounds the base of terraformed holes, giving units the space to peer into the hole and shoot whatever is at the bottom.
  • A small amount of terrain deformation occurs while the base cost of the terraform is being spent.


There is now a keybind system for issuing Level and Raise terraform commands with preset heights.
  • Navigate to Hotkeys/Construction/Level or Hotkeys/Construction/Raise in the ingame menu.
  • Set the parameters (height and culling) for one of the ten terraform presets.
  • Click 'None' and press a key combination.
  • Press the key combination to issue a terraform command that is executed after the drawing step - no height selection required.

Ctrl-Click can now be used on the selected unit panel to filter selections in a new way. To use it:
  • Select some units.
  • Hold Ctrl.
  • Left click on some unit potraits (Shift+Click to select all units of a type).
  • Release Ctrl.
  • The units clicked on while Ctrl was held become the new selection.


  • Underwater wreckages bubble instead of smoke.
  • Torpdoes and depth charge projectiles are now much easier to see. Hunter was feeling particularly lackluster due to the difficulty in discerning its targets.


  • Fixed some technology descriptions in the campaign.
  • Fixed Placeholder overkill prevention.
  • Djinn no longer teleports units to terrain with an impassible movement modifiers.
  • Removed Seawolf impulse. This prevents it from pushing ships out of the water and carrying them on its back.
  • Tweak collision volume for Minotaur wreckage and Tidal Generators.
  • Envoy and Emissary avoid shooting into terrain (this was intended, the theory being that their cratering was sufficient to break down walls).
  • Optimised some parts of healthbar drawing. Fiddled with the settings and made the text fade out at lower zoom levels.
  • Fixed Scylla firing more than one tacnuke when the intention was to only fire one.
  • Fixed cloak ranges widget crashing when an unseen enemy unit is selected.
  • Fixed a crash in the construction height widget related to clicking outside the map.
  • Fixed areamex construction ghost positions in the sea.
  • Fixed Crane nanospray.

Zero-K v1.8.3.2 - Tank Raiders and Commander Diversity

In this version the Tank Foundry is bestowed with two reliable raiders, there are some tweaks for Hover and Rover, and we make an attempt at diversifying the commander chassis. Amphibious units have some minor tweaks and major fixes as part of the continual attempt to make them more generally useful.

In non-unit changes, terraform can no longer be used near enemy units. This removes a source of APM frenzy and allows terraform to be buffed for other purposes. There is a new variant of Brutal AI and we have added a few hooks in the game definitions that make it easier to mod.


Added a Brutal AI personally with a focus on economy and escalation.


Kodachi is now a more standard raider. Instead of a single large, high-reload, large fireball it fires a stream of small fireballs. The fireballs travel quite slowly, giving fast units a chance to get away, and only burn the ground for 1.5 seconds. It has received some health and speed nerfs to bring it more in line with other raiders.

Blitz is a little heavier and slower, since Kodachi should be able to take up more raiding responsibility.
  • Cost 280 -> 300 (where it was before all the tweaking)
  • Health 1100 -> 1250
  • Speed 102 -> 97.5
  • Reload 2.6333 -> 2.6

Ogre is better against small units and those that try to run away.
  • Can shoot at retreating targets at max range.
  • Fires two missiles, Picket-style, with a gap of 0.3s
  • Reload 2.133s -> 2.3s
  • Damage 420 -> 2x240

Scorcher regains some of the DPS it lost in the superfluid update.
  • DPS increased by 5% (84% of previous, up from 80%).

Fencer became a little too manoeuverable and needs less damage if Hover is to be more viable.
  • Reduced manoeuverability (still greater than pre-superfuild).
  • Reload time 0.733s -> 0.766s

Ripper is still finding its place after becoming a more buildable unit.
  • Health 1100 -> 1020
  • Speed 66 -> 63
  • Turn Rate 707 -> 624 (was 442)
  • Reload 1.7s -> 1.766s
  • Damage 270 -> 260
  • Range 285 -> 280
  • Sight Distance 347 -> 350

Dagger is one of those knife-edge units and needs small tweaks.
  • Range 220 -> 215 (was 210).

Bolas is better at escorting.
  • Health 720 -> 780
  • Range 220 -> 230

Claymore might see use on land.
  • Cost 330 -> 320
  • Land Range 160 -> 220

Reaver has a tweak to make it better against Glaive.
  • Range 270 -> 275
  • Damage 40 -> 45
  • Reload 0.466 -> 0.5
  • Sight Distance 345 -> 350

Conch needs to be faster for Amph to be more generally useful, and now has a unique ability.
  • Speed 51 -> 54
  • Armours while idle.

Duck has room to be a decent sea raider thanks to the other changes to sea.
  • Torp range 150 -> 210

Scallop deals more AoE damage to non-primary targets to make it a bit better against Ducks.
  • Depthcharge Edge Effectiveness 0 -> 0.6

Lobster is finicky enough without a high fire delay.
  • Multiplied aim rate by 3.

Seawolf is better at bursting down enemy ships.
  • Damage 250 -> 260

Funnelweb can no longer block two Shockleys.
  • Max Shield 23000 -> 19400

Terraform can no longer be worked on when enemies are nearby.
  • Buildrate slows by 50x while visible enemy units are nearby.
  • Made all terraform segments cheaper by 12.


It is time to address the dominance of the Recon chassis. Instead of nerfing jumpjets, and potentially ruining the fun, we're differentiating commanders by buildpower and buffing the other chassis.

Recon uses jump to expand rapidly and a BP nerf tones down this advantage.
  • Buildpower 10 -> 8

Strike is made distinctive with more speed than Guardian.
  • Speed 40.5 -> 43.5
  • Regen 5/5/12.5/20/27.5/35 -> 5/5/10/16/25/35

Guardian is fairly plain so it has gained drones as an experiment.
  • Added Light Drones: 1/1/2/2/3/3
  • Added Heavy Drones: 0/0/0/1/1/2
  • Companion Drone build delay 15s -> 12s (all chassis)
  • Battle Drone build delay 25s -> 18s (all chassis)

Support needs to be faster to compete with other chassis.
  • Speed 36 -> 39
  • Buildpower 10/12/14/16/18/20 -> 12/14/16/18/21/24

Speed modifiers are now absolute rather than relative, and cloaking comes with a speed penalty.
  • High Power Servos: Speed +8% -> +3
  • High Density Plating: Speed -10% -> -3
  • Damage Booster: Speed -2.5% -> -1
  • Adv. Targeting System: Speed -2.5% -> -1
  • Added a speed penalty of -8 to Personal Cloak.


  • Maps that include gamedata/unitdefs_post.lua have it loaded in addition to the game version, instead of replacing it.
  • Multiple morphs for a single unit can now be set in customParams.


  • Fixed Scallop depth charges failing to reach their target in shallows.
  • Duck and Scallop torpedo projectiles hit more consistently.
  • Fixed the little jump that sometimes happens to floater units when they reach the sea floor.
  • Floating units thrown by Lobster now float correctly when they hit the water.
  • Crab now fires while changing state and is no longer 'stunlocked' by swarms of units shooting at it.
  • Fixed a target retention issue caused by quickly issuing Force Fire then Move orders.
  • Added startboxes for Barracuda Bay, Blindsidem Oktagon v3 and TL Dropzone.
  • Removed swarm AI for units fighting Knight.
  • Space+Click unit information shows commander drones.
  • Made some selection circles better match unit size.
  • Fixed Bandit and Scorcher sometimes shooting sideways.
  • Potentially fix a morph bug that allowed facplop to be duplicated.

Zero-K v1.8.3.1 - Bolas, Puppy and Scallop Followup

Three units, Bolas, Puppy and Scallop, were a bit overtuned and so they are the focus of this patch. As a new unit, it is better for Bolas to be a bit on the side of OP, Puppy will be revisited later, and Scallop was too good against units intended to force it to the surface. Big seismic effects now ignore structures and there are some small raider tweaks.


  • Health 760 -> 720
  • Range 225 -> 220
  • Reload Time 0.3s -> 0.33s

  • Reverted changes from v1.8.3.0.
  • Cost 50 -> 45
  • No longer cloaks while reclaiming.
  • Added a goo gather state with options Off, On except cloaked (default), and On always.

  • Health 240 -> 230

  • Health 340 -> 330

  • Increased DPS by 5%

  • Range (both weapons) 300 -> 285

  • Range 340 -> 355
  • Fixed tactical AI
  • Decreased hitvolume size to match the model
  • Increased brake rate by 19%
  • Decreased turn rate by 11%

Quake, Detriment and Disco Rave Party smoothing now affects structures.
  • Quake radius 256 -> 320
  • Improved the smoothing effect so vehicles are more able to use Quaked hills.


  • Removed the Cancel Retreat hotkey from deep in the Settings menu. Fixed the Cancel Retreat hotkey in the Hotkeys menu.
