Zero-K v126.96.36.199 - Shield, Spider, Hover and Tank
Lobster Roll series two will start on the 17th of April and is open to everyone. There is a round robin warm-up tournament this coming weekend, on the 10th of April. Sign up to the round robin here. Join the Discord server for announcements about the upcoming series.
The following changes have been applied to the matchmaking pool. The full pool can be viewed here.

- Removed - Sparkles Reef, Prestige, Otago, Iced Coffee, Ravaged, Mechadansonia.
- Updated - Cobalt Dream, Dune Patrol Redux, Fallendell.
Shieldbots are the main issue among the bot factories, and it was not just an issue of overall power. Players in the middle of the ladder were having trouble against the Shield midgame, while those at the top found Shield to be at too much of an early disadvantage. To solve this we buffed their early game while nerfing the standard shieldball. We have also tweaked Spiders to make them less reliant on Venom.
Bandit is a bit better to help Shieldbots through the early game.
- Health 330 -> 340
- DPS increased by 2.5%
Convict is faster to assist early expansion.
- Speed 60 -> 61.5
Rogue has a nerf to save some matchups from mass Rogue supported by the buffed Bandit.
- Health 580 -> 540
- Turn rate reduced by 10%.
- Projectile velocity 192 -> 185
- Damage 350 -> 340
Thug regenerates slower to make shield charge more valuable.
- Speed 57.75 -> 57 (what a weird number, now same as Outlaw)
- Shield capacity 1250 -> 1200
- Shield regen 16/s -> 14/s
Felon has 18.8% less DPS and charges slower.
- Shield regen 18/s -> 16/s
- Aim time 0.3s -> 0.166s
- Reload 0.13s -> 0.16s
- Charge per shot 75 -> 80
- Damage 108.4 -> 110
Outlaw takes on more responsibility for riot power from Felon.
- Cost 260 -> 250
- Health 1050 -> 1100
- DPS increased by 13%
Vandal takes on more responsibility for anti-air power from Felon.
- Range 880 -> 900
Racketeer is slightly easier to field.
- Cost 350 -> 340
- Speed 51 -> 52.5
Snitch is slightly harder to position.
- Speed 120 -> 117
Dirtbag is better at spotting and harassing.
- Speed 78 -> 84
- Sight range 560 -> 600
- Reload 2s -> 1.9s
- Damage 45 -> 55
Reaver has a buff to help Glaive deal with Bandit.
- Cost 220 -> 210
- Speed 1.71 -> 1.75
- Reload 0.5s -> 0.466s
Flea is harder to spot when burrowed.
- Decloak Radius 200 -> 160
Venom has less stun uptime, as well as slightly less DPS.
- Reload time 1.1s -> 1.133s.
Hermit is one of the more maligned assaults, so gains some assault power.
- Cost 160 -> 150
- Health 1400 -> 1500
Widow drains more energy to make it harder to field early on.
- Cloak cost 12/4 -> 15/5 (Moving/Static)
Rover is dominating the vehicle matchups, yet there were few complaints about Rover itself. We took this to mean that Rovers feel fun and well balanced, even when losing to them, so opted mostly leave the factory alone. Instead, we took a look at Hover and Tank. Hover has a decent earlygame but a lack of transitions, so we buffed some of their more niche units, while Tank has the opposite problem, so we buffed Tank earlygame.
Fencer is more vulnerable.
- Health 560 -> 530
- Setup time is 6.6% longer
Quill is now only slightly more expensive than a standard constructor.
- Cost 130 -> 125
Halberd can be unleashed now that Anti-Bait makes it less annoying to fight.
- Cost 240 -> 210
Mace is a better riot at the expense of a little range.
- Health 1300 -> 1400
- Range 345 -> 340
- Aims 20% faster
- DPS increased by 10%
Kodachi feels fairer to fight so can afford a buff.
- Cost 180 -> 175
- Health 670 -> 680
Welder is cheaper but also more vulnerable to raiders.
- Cost 200 -> 185
- Health 1800 -> 1700
- DPS reduced by 4%
Ogre needs a buff to fight Mace 1v1 and win.
- Health 1850 -> 1950
There are now some optional resource panels to enable under 'Settings/HUD Panels/Economy Panel' with Simple Settings disabled. They need to be positioned with Ctrl+F11. There are two panels to track constructor activity, a panel for overdrive, and a panel for wind speed.
- Added Shield Charge/Maximum to aggregate selection stats and switched some rows to improve order stability.
- Added Avoid Bad Targets toggle for Claw, Ultimatum, Scorpion and Nimbus.
- Nimbus flies a little closer to make it reliably fire at tall turrets.

- Landbound Urchins are better at firing into the deep ocean.
- Fixed transports having trouble unloading tall units.
- Fixed some edge cases with antinukes.
- Fixed Ravager suspension.
- Tacnuke sounds now play at higher priority.
Zero-K v1.9.30 - Anti-Bait Update
There are few actual balance changes to better observe the ramification of the latest advances in unit command. Apart from that there are a few features and fixes, such as the ability to click on names in the endgame stats to highlight a line, and improved map filtering.
Advanced Radar moves towards justifying its cost, as an experiment.
- Cost 500 -> 400
- Sight 800 -> 1120
- Range 4000 -> 5600
Claymore has a smaller collision volume.
Duck missiles have less fuel, but still enough to hit land targets.
Jugglenaut and Newton now have aim lookahead (aiming towards targets that are about to enter range).
Units and turrets reload time or costly projectiles can now be told to avoid low value targets. This can be configured under Settings/Unit Behaviour or controlled with the Avoid Bad Targets state, which is shown by default. The states are:
- Free - Avoid light drones, Wind, Solar, Claw (Badger mines), Dirtbag, nanoframes up to 50 metal and armoured targets (except Crab).
- Light - As above, as well as units costing less than 90, Razor, Sparrow and unidentified radar dots.
- Medium - As above, as well as units costing less than 240, except Stardust, with the addition of Raptor.
- Heavy - As above, as well as units costing less than 420.
Some units default to Free and a few default to Light. The behaviour is overridden by Attack Move as well as manual targeting.
Units are also more opportunistic when it comes to fighting shields, now firing at nearby small shields if nothing else is in range. Most non-artillery do this and it is essentially a range buff against shieldballs. This behaviour, called Ward Fire, can be configured in Settings/Unit Behaviour or enabled as a state toggle under Settings/Interface/Commands.
There are also a few improvements to Attack Move.
- Siren brings its main gun into range on Attack Move.
- Most skirmishers and assaults no longer engage drones on Attack Move, however they will still fire at them if nothing else is in range.
- Individual players can now be highlighted in the endgame graphs by clicking on their name.
- Improved the filter box of the map list.
- Renamed 'Map Selection' to 'Set Map Bans' in the Matchmaker Tab.
- Selecting Puppy, Athena, Caretaker and Strider Hub enables the reclaim highlight overlay.
- Unit info screens now show movement type.
- Clarified Reaver and Hercules helptext.
- Greased Tremor rotary drive.
- Fixed Crab curling?
- Fixed Adamantine Mountain team names.
- Fixed newly constructed units sometimes not following factory waypoints.
- Fixed overkill prevention sometimes knowing too much about unidentified radar dots.
- Fixed trouble toggling Puppy Goo.
- Fixed some parts of long terraform queues being cancelled prematurely.
- Removed Leaper Chickens from planets Sapphire and Vis Ragstrom.
Zero-K v188.8.131.52 - Hot Stardust and Curtailed Cloaking
Other changes include an excellent new walk animation for Outlaw and some behaviour fixes for Attack-Move.
Duck reliably hits units as small as Glaive, but lost a little range. It is a little sad to see a physics trick go, but Amphbots should not be balanced around around swingy raider interactions.
- Land range 240 -> 235
- Projectile velocity increased by 10%
- Projectile turn rate increased by 39%
Venom lost some range and health.
- Range 245 -> 240
- Health 750 -> 740
Dagger lost the most range because it is the fastest.
- Range 212 -> 205
Blitz didn't lose any range because it is not as popular as other burst damage raiders.
Claymore is more reliably useful, but we are taking care to not make it too powerful too quickly.
- Health 1260 -> 1300
- Projectile speed increased by about 50% (both on land and sea)
- Range 300 -> 280 (both on land and sea)
Sling loses some damage in sympathy with Stinger.
- Damage 150 -> 140
Badger loses most of the 25% damage buff caused by fixing its 5th Claw bomblet.
- Mine damage 200 -> 170.
Tremor finally loses the ability to fire while moving, and must pack up to move.
Stardust now 'heats up' as it fires, reducing fire rate as it does so. This allows it to retain most of its power against raiders while dealing less sustained damage to tankier assaults.
- Gains 3.8% heat per shot.
- Loses 14.3% per second.
- Slow scales up to 50% at max heat.
- Starts with 100% heat.
Faraday is more of a weighty choice.
- Cost 250 -> 260
Gauss deals less damage to lean into its anti-artillery role.
- Reload 2s -> 2.1s
Stinger is less efficient and easier to assault.
- Cost 420 -> 450
- Health 2475 -> 2250
Starting metal is lower to give small units a bit more space to breathe.
- Income +6 metal, +8 energy -> +5 metal, +8 energy (-1 metal income for commanders).
- Initial resources 300 metal and energy -> 250 metal and energy.
Cloaking an army for general combat is now harder and less effective.
- Iris radius 440 -> 400.
- Increased recloak time for area cloaking 5s -> 6s.
- Default decloak radius for area cloaking is now 12*footprint + 56, instead of 75. This means most units have a decloak radius of 80, 92 or 104.
- Imp and Snitch, which have their decloak radius increased 75 -> 80. Other units with personal cloak are unaffected by the decloak radius change.
Companion Drones are cheaper and easier to catch with raiders.
- Cost 300 -> 200
- Range 180 -> 150
- Cruise Alt 100 -> 85
- Guardian progression 1/1/2/2/3/3 -> 1/1/2/2/2/3
Battle Drones are also cheaper, but Guardian Chassis only receives one for free.
- Cost 500 -> 350
- Range 240 -> 200
- Cruise Alt 100 -> 95
- Guardian progression 0/0/0/1/1/2 -> 0/0/0/0/1/1
Fractional reload times resulting from status effects are now rounded to the nearest frame, rather than round down. This buffs units with slow damage, particularly against units with a high rate of fire.
- Moving now consistently grants immunity to being kidnapped by enemy transports.
- Units on Attack-Move now periodically reset their target. This ensures that they don't end up chasing retreating enemies through enemy lines.
- Improved Emissary movement packing.
- The Alt+N default terraform hotkey makes slightly higher walls.
- Added a Caretaker deathclone, it blocks movement like most deathclones.
- Made it a little easier to shoot Lotus and Stinger from the bottom of cliffs.
- Tactical AI is off by default for Emissary.
- Improved Outlaw walk animation.
- Increased Bulkhead icon size slightly.
- Added checkbox options for unit halos, platters, selection halos, and selection shapes.
- Teamplatter widgets use the same base scaling as selection shapes.
- Map dimension and type are now shown below the map in the lobby.
- Fixed EMP breaking factories.
- Fixed Archer unit AI sometimes closing range inappropriately.
- Fixed Puppy Gather settings under Unit Behaviour not being applied.
- Damaging or killing drones no longer counts towards endgame stats.
- Reduced the permeability of the side walls of Shielbot Factory, Cloakbot Factory and Hovercraft Platform.
- Fixed camera state recall and ctrl/alt+MMB rotation jitters for COFC (the advanced camera).
- Fixed build spacing widget crash on rapid camera rotation.
- Disabling a selection widget no longer enables the basic selection squares if any other selection widget is enabled.
- Fixed Area Mex with Space, and no other modifiers, held.
- Fixed map terraform masking not applying to smoothing.
