StarCraft II's Cool, Sometimes Crazy Single Player Liberties

Blizzard is creating a wildly different experience for those who choose to play StarCraft II: Wings of Liberty's single-player campaign, adding units, vehicles and upgrades that you just won't see in multiplayer, from the familiar Firebat to the bizarre Predator.

The last time we played StarCraft II's single-player game, we laid out the unit, base and ship upgrades that will trick out units with special abilities you won't see in multiplayer games. At the time, that included the return of units from the original StarCraft, like the Goliath and Firebat. It also included units that Blizzard opted to cut from the multiplayer side.

Our most recent hands-on time with StarCraft II illustrates how Blizzard is splitting the upgrade path. Previously, all unit upgrades were purchased with in-game credits acquired by completing successful missions. Now, in the research Laboratory, players will need to spend the Protoss relics and Zerg genetic material they find scattered throughout maps on a set of race-specific upgrades.

The new research upgrades follow a skill tree-like path. There are a total of 20 upgrades, 10 for the Zerg and 10 for the Protoss. As shown in the screen shot above, each race research path is split into two columns. As you acquire the necessary research materials, you'll have to make a choice as to which upgrade you'll commit to.

Some of these research upgrades are very rewarding, like the automated Vespene gas Refinery for the Terrans and the Orbital Depots, which drop in pre-fab Supply Depots wherever an SCV worker points. Some are classic units, like the Science Vessel, unavailable otherwise. Some, like the Predator, a mechanised battle cat that attacks infantry, are just weird.

Here's the list of Research upgrades from the latest build of StarCraft II.

Protoss Research

  • Ultra-capacitors (5) - Weapon upgrades in armory and engineering boost attack speed by +5% in addition to damage.
  • Vanadium Plating (5) - Upgrades in armory and engineering boost health by +5% in addition to armour.
  • Microfiltering (10) - Harvest Vespene gas 25% faster.
  • Orbital Depots (10) - Supply depots build instantaneously.
  • Command centre Reactor (15) - Build two SCVs simultaneously.
  • Automated Refinery (15) - No longer requires SCVs to harvest Vespene gas.
  • Science Vessel (20) - Unit that detects cloaked and buried units, irradiates enemies and repairs mechanical units nearby.
  • Raven (20) - Unit that detects cloaked and buried units, drops auto turrets, fires seeker missiles and deploys point defence drones.
  • Tech Reactor (25) - Combination tech lab and reactor add-on.
  • Orbital Strike (25) - Units built at Barracks now arrive by drop pod and land at rally point.

  • Psi Disruptor (25) - Slows Zerg movement.


    The worstest thing in the game is by far, the locked game speed on hard and brutal in campaign and the forced default high game speeds. Despite all the good things in game (and are many, some described in this article), this make the game annoying and boring, ruined it. At casual and normal difficulties, the player can control the game speed, but the AI is not strong enough to be a challenge. On hard or brutal, the AI is a challenge even for skilled players, but the micromanagement is impossible at such speeds, so, the game become one arcade game, not a RTS. Idem on multiplayer, players just rush, so, we cannot see here great tactical and strategic abilities, only fast button push (the player who have a better computer, a more responsive keyboard and mouse is in great advantage from start) The designed by default hotkeys-based gameplay make the game experience more sluggish, and frustrating, not more smoothly. The mass cast abiltities lack entirely, also many players regrets the units from Starcraft I and Broodwar. For that causes, Starcraft II, despite the 3D graphic and other improvements, many mentioned above, is not such a great hit like SC I and Broodwar at that time. Somebody from the game-stuff imposed with obstinacy a wrong personal vision about to way to play the game, and from that point are resulted all game failures and lack of game joy for many players.
