All Game Items for StarCraft II: Wings of Liberty



This guide covers all major items, weapons, armor, consumables, materials, currencies, collectibles, and key equipment available in StarCraft II: Wings of Liberty. Items are categorized logically with details on what each does, how to obtain it, when it is useful, and important synergies or upgrades.

Resources (Materials)


Resources are the foundation of any strategy in StarCraft II.
  • Minerals: The primary resource. Used to build nearly all structures and units. Gathered by workers (SCVs, Probes, Drones) from mineral patches. Early game bottlenecks are minerals. Synergy: Always have at least 16 workers per mineral line for optimal saturation.

  • Vespene Gas: The secondary resource. Required for advanced units, upgrades, and structures. Gathered from Vespene Geysers by building refineries (Terran), assimilators (Protoss), or extractors (Zerg). Essential for tech-heavy compositions like Battlecruisers or High Templar.

  • Supply: Not a gather-able resource but a cap on unit count. Terran uses Supply Depots, Protoss uses Pylons, Zerg uses Overlords. Increase supply to field larger armies.


    • Currencies


  • Minerals & Vespene Gas: The two main currencies in multiplayer and campaign. No other currencies exist in standard gameplay.

  • Campaign-only Currencies:

    • - Credits: Earned by completing mission objectives and finding secret caches. Spent at the Armory and Science Lab to purchase unit upgrades and research. Obtain: mission rewards, hidden pickups. Used throughout the campaign.
    - Protoss Artifacts: Special items collected during the campaign. Used to unlock and upgrade the Spear of Adun (in later expansions) but in Wings of Liberty, they are plot devices. Not a spendable currency, but required to progress story.

    Weapons and Armor Upgrades


    Weapons and armor upgrades increase the damage dealt and damage reduction of units. They are race-specific and stack with each tier.

    Terran Upgrades (obtained from Engineering Bay for infantry, Armory for vehicles and ships):
  • Infantry Weapons (Tiers 1-3): +1 attack per level for Marines, Marauders, Ghosts, etc. Synergy: Marines with Stim and +3 weapons shred lightly armored units.

  • Infantry Armor (Tiers 1-3): +1 armor per level. Vital for bio balls to survive splash damage.

  • Vehicle Weapons (Tiers 1-3): +1 damage per level for Siege Tanks, Hellions, etc. Synergy: Siege Tanks with +3 weapons one-shot certain units.

  • Vehicle Armor (Tiers 1-3): +1 armor per level. Useful for tank-heavy compositions.

  • Ship Weapons (Tiers 1-3): +1 attack per level for Vikings, Banshees, Battlecruisers. Crucial for air superiority.

  • Ship Armor (Tiers 1-3): +1 armor per level. Helps Vikings survive longer.


    • Protoss Upgrades (Forge for ground, Cybernetics Core for air):
  • Ground Weapons (Tiers 1-3): +1 attack for Zealots, Stalkers, etc.

  • Ground Armor (Tiers 1-3): +1 armor.

  • Air Weapons (Tiers 1-3): +1 attack for Void Rays, Phoenix, Carriers.

  • Air Armor (Tiers 1-3): +1 armor.


    • Zerg Upgrades (Evolution Chamber):
  • Melee Attacks (Tiers 1-3): +1 damage for Zerglings, Ultralisks, etc.

  • Missile Attacks (Tiers 1-3): +1 damage for Roaches, Hydralisks, Mutalisks.

  • Carapace (Tiers 1-3): +1 armor for all Zerg units.


    • Obtain: Upgrade research requires the appropriate building (e.g., Engineering Bay for Terran infantry), time, and resources (minerals and gas). Higher tiers require previous tier. Useful at all stages of the game. Synergy: Upgrade timings often coincide with tech switches (e.g., +2/+2 bio into +3/+3).

    Consumables (Abilities and Call-downs)


    These are one-time use abilities that can be activated during combat or base management.

    Terran (Orbital Command):
  • M.U.L.E.: Call down a mechanical unit that automatically gathers minerals at high speed. Cooldown 60 seconds. Use early/mid game to boost economy without building more SCVs. Synergy: Use on rich mineral patches only.

  • Scan: Reveals an area of the map for 12 seconds. Detects cloaked/burrowed units. Cooldown 60 seconds. Essential for detecting DTs, Banshees, or burrowed Roaches. Also useful for scouting.

  • Calldown: Extra Supplies: Instantly builds a Supply Depot at target location. Cooldown 60 seconds. Use to avoid supply block or to quickly wall off ramps.


    • Protoss (Nexus):
  • Chrono Boost: Accelerates a selected structure's production or research by 50% for 20 seconds. Cooldown 45 seconds. Use on Cybernetics Core for upgrades, or on Robo/Stargate to pump units.


    • Zerg (Hatchery/Lair/Hive):
  • Larva Inject: Spawns 4 additional larvae at target Hatchery. Cooldown 40 seconds. Crucial for maintaining unit count. Synergy: Use macro hatch (extra Hatchery) for more larvae.

  • Creep Tumor: Spreads creep to expand vision and speed up Zerg units. Cooldown 15 seconds. Place tumors in a chain to cover map.


    • Collectibles (Campaign Only)


  • Secret Documents: Found in some missions (e.g., "The Outlaws"). Rewards credits.

  • Specialist Units: Not collectibles, but unlockable via research.

  • Armory Upgrades: Purchasable with credits. Examples: Marine Shields (+10 HP), Siege Tank Artillery (+range). Each improves specific units.


    • Key Equipment (Unique Units and Structures)


  • Hyperion (Battlecruiser): Campaign hero unit with higher stats and abilities. Available in certain missions.

  • Odin: Giant mech unit used in campaign. Powerful ground siege.

  • Science Vessel: Support unit with abilities like Defense Matrix and Irradiate. Campaign only.

  • Raven: Terran caster with Auto-Turret, Seeker Missile, and PDD. Useful for disabling enemy units.

  • Mothership: Protoss capital ship with cloaking field and black hole. Extremely rare, built from Fleet Beacon.


    • Notes on Synergies and Upgrades


  • Weapon/armor upgrades stack multiplicatively with attack speed and abilities (e.g., Stim increases rate of fire, making weapon upgrades more valuable).

  • Always prioritize upgrades according to your composition: if going bio, get infantry weapons/armor; if mech, get vehicle/ship upgrades.

  • Campaign upgrades are permanent between missions but reset on new playthrough.
