CO-OP MISSIONS

Abathur

• Brutalisks can now use Nydus Wurms.

Alarak

• Army shield color is now red.
• Dev Comment: Alarak and Fenix's shield color is now themed red for Tal'Darim and yellow for Purifier.
• Vanguard
  • Now uses turret tracking.

Dev Comment: Many units that can turn to face their enemies now do. These units should now feel more responsive.

Artanis

• High Templar and Archons
  • Plasma Surge research now increases Psionic Storm’s radius by 50%, range by 2, and restores 50 shields to friendly units.

Dev Comment: This research now matches the bonuses to that of the Legacy of the Void campaign's improved High Templar.

• Immortal
  • Now uses turret tracking.
• Mastery: Speed Increases for Warped-In Units
  • Bug Fix: No longer causes buffs and debuffs to time out early.
• Tempest
  • Bug Fix: Weapon upgrades now grant +5 damage (up from +3).

Dehaka

• Tyrannozors
  • Unit collision size has been reduced to match a standard ultralisk.

Dev Comment: They should now be much more effective in combat (and in going up small ramps!).

• Greater Primal Wurm and Primal Wurm
  • Bug Fix: Knockback effect on unburrow no longer affects air units.
• Glevig:
  • Incendiary Acid ability is no longer on autocast by default. Changing the state will carry over to subsequent summons.

Fenix

• Army shield color is now yellow
• Fenix Armor Suits
  • Base offline energy regeneration for all suits increased by +25%.
  • All suits gained an addition +1 Armor and +1 Shield Armor.
  • All suits gained an additional 5 damage.
  • Purifier Armaments research now increases all Fenix Armor Suits weapon damage by +15.
  • Arbiter:
    • Made the stasis ability instant cast and castable while moving.
  • Praetor:
    • Whirlwind damage increased to 70 per second.
    • Now ignores enemy armor.

Dev Comment: Increased offline energy regeneration allows Fenix to use more of his abilities while keeping his suits-swapping mechanic intact: swapping frequently to be the most effective. We wanted to increase a few stats to hit a few critical break points in basic combat. His basic attacks will now one shot Zerglings and Whirlwind will one shot them with each damage tick (0.5 seconds). Fenix fears no Zerg! These two changes also effectively buff the masteries in the first category.

• Research Costs
  • 50% reduction to most research costs. Does not affect common shared standard protoss research (Colossus Range, Observer speed, warpgate, etc).
  • Remove gas cost on Kaldalis AI research. Total is now 100 minerals.

Dev Comment: As mentioned in a previous update, this is a major change to Fenix's economy and ramp up time. It should have a dramatic effect on his ability to ramp up as well as his overall power.

• Champions
  • Champion AI transfer time reduced from 5 seconds to 1 second when killed.

Dev Comment: Along with some bug fixes in a previous update, this should dramatically improve the responsiveness and effectiveness of champion transfers.

• Tactical Data Web
  • Change all bonuses to scale based on supply instead of unit count.
  • All buffs now stack up to 20 supply to reach max power.

Dev Comment: This mechanic as also been buffed. Higher tier units now require less additional shells (ex: 4 Colossi instead of 10) to maximize the bonus effect.

• Avenging Protocol
  • The upgrade has been reworked.
  • Champions gains attack and move speed (5% per supply) each time a host shell of their type is destroyed or a 25% speed increase when they transfer into new host shell. Speed increases can stack up to 100% and last for 10 seconds if not refreshed.

Dev Comment: Avenging Protocol now also grants bonuses to the champion when host shells of their type are destroyed. The duration of the bonuses also can be refreshed each time a shell is destroyed. As discussed in a previous post, this is intended to alleviate the pressure to have champions dying first and often to benefit from this upgrade.

• Masteries
  • New Mastery: Staring Supply: Increases the starting supply by 1 per point.
  • Removed research cost reduction mastery.

Dev Comment: Now that Fenix's unique research upgrade costs have been dramatically reduced, he no longer needs a cost reduction mastery. Instead he gains a subtle but powerful new macro mastery which gives him a big boost in econ ramp up speed.

• Carrier
  • Interceptors now cost 15 minerals.

Dev Comment: Long ago we defaulted interceptors to autocast for campaign and coop. We were worried that an ability on autocast that spent money would be detrimental and confusing to some players, so we made interceptors free. Multiplayer interceptors have been autocast for a while and it seems to be working out, so we're matching the multiplayer interceptor cost and leaving build interceptors on autocast.

• Conservator
  • Increase radius of Protective Field By 1.
  • Increase duration of the field to 15 seconds (30 with upgrade).
  • Cooldown reduced to 20 seconds.
  • Phasing Mode
    • Channels a larger protective field centered on itself that lasts indefinitely.
    • Removed the ability to cast the field while in this mode.

Dev Comment: We added a new mechanic to phase mode which channels a field indefinitely. The conservator should be more interesting to use as well as gaining an overall buff in protective field up time.

• Immortal
  • Now uses turret tracking.
• Mojo
  • Tactical Data Web
    • Redesigned: Increase stun duration by up to 2 seconds (100%) at max.
• Taldarin
  • Increase the radius of the graviton disruptor by 0.5 (to 2.5).
• Talis
  • Shield Armor
    • Increased to 1.
  • Tactical Data Web:
    • Redesigned: Ricochet Glaive cooldown reduced by up to 5 seconds (100%) at max.

• Warbringer
  • Basic Attack
    • Area of Effect length increased by 100%.
  • Tactical Data Web:
    • Redesigned: Purification Blast cooldown reduced by up to 5 seconds (100%) at max.

Karax

• Immortal
  • Now uses turret tracking.
• Carrier
  • Interceptors now cost 15 minerals.

Nova

• Siege Tank
  • Now uses turret tracking.

Raynor

• Battlecruiser
  • Tactical Jump now requires vision.

Dev Comment: We are standardizing Tactical Jump across all commanders to require vision. Raynor can still use Orbital Scan to jump anywhere, but other commanders will have to gain vision in other ways before jumping. The Hyperion is special and can still jump without vision.

• Siege Tank
  • Now uses turret tracking.
• Mastery: Speed Increases for Drop Pod Units
  • Bug Fix: No longer causes buffs and debuffs to time out early.
• Factory
  • Drop Pods are now more lenient on valid rallied drop locations similar to the barracks.

Stukov

• Infested Diamondback
  • Caustic Mucus
    • Damage increased from 5 to 20 damage per second.
    • Tooltip now states the damage done.
  • Fungal Snare
    • Increase cast range to 8.
    • Now shows a range indicator.
• Infested Siege Tank
  • Range while rooted increased from 13 to 18.

Dev Comment: We're buffing Stukov's mech a bit to strengthen their roles.

Swann

• Siege Tank
  • Now uses turret tracking.
• Hercules
  • Tactical Jump now requires vision.

Vorazun

• Mastery: Speed Increases during Time Stop
  • Bug Fix: No longer causes buffs and debuffs to time out early.

Enemies

• Bug Fix: Banelings should now properly trigger the following on death effects:
  • Drop Assimilation Aura resources (Kerrigan)
  • Drop Bio Mass (Abathur)
  • Spawn Locust (Abathur)
  • Drop Essence (Dehaka)

STARCRAFT II API

• New features have been added to the StarCraft II API
  • A new rendered interface is now available on all platforms, including Linux.
  • A new option has been added to create and load save points in the game simulation.
  • A new function has been added to the Game Data API for downloading anonymized ladder replays.
  • For more information, see the release notes on our GitHub page.

STARCRAFT II EDITOR

• 4.0 Galaxy Changes and Optimizations
  • The virtual machine has been heavily optimized and refactored.
  • Trigger specific loop optimization behavior has been modified in the following triggers:
    • ForEachInteger
    • ForEachInteger2
    • PickEachInteger
    • IntLoopCurrent
    • ForEachPlayerInGroup
    • PickEachPlayerInGroup
    • PlayerGroupLoopCurrent
    • ForEachUnitInGroup
    • PickEachUnitInGroup
    • UnitGroupLoopCurrent
    • switch/switchcase

Dev Comment: These changes now require that IntLoopCurrent, PlayerGroupLoopCurrent, and UnitGroupLoopCurrent be “lexically” rather than “dynamically” scoped within their loops. For example, before, you may have had a trigger that had an outer ForEachInteger, ForEachPlayerInGroup, or ForEachUnitInGroup, and an inner function that would call a trigger that would access IntLoopCurrent, PlayerGroupLoopCurrent, or UnitGroupLoopCurrent. Moving forward, you will need to either make sure to call these triggers consecutively with each other or pass in IntLoopCurrent, PlayerGroupLoopCurrent, or UnitGroupLoopCurrent as a parameter to your trigger that uses the loop iteration.

• These modifications include a modified code generation upon sc2maps being saved or resaved within the editor.
• Maps that were made using the older Galaxy system are backwards compatible with the new Galaxy if they aren't resaved, but they won’t have loop optimizations.
• The TriggerDebugInterface has been revamped to adhere to the new modifications.

• UI Editor Changes
  • Removed the FrameView from the UI Editor.
  • Changed to always save your layout xml in whatever form it is in.
  • Added xml error message output during saving layout files when an error occurs.
• Mod Changes
  • Moved Buildings, Effects, Portraits, Doodads, Units, and TerrainObjects from Liberty campaign mod to Liberty mod.
• Interface Changes
  • Added Enable Dark Editor Theme general preference option checkbox.
  • This will currently toggle on and off a dark mode when editing xml.
