Background--In Brood War, the saga of galactic warfare between the Zerg, Protoss and Terrans continues
			where the original left off at its conclusion.
			
          With the shattered Zerg hive torn apart by fierce in-fighting, the 
            Protoss seek to reunite with their Dark Templar brethren and begin 
            the rebuilding of their homeworld, Alur. It is inevitable that trouble 
            will follow them, and thus the Protoss must battle the Zergish horde 
            on the Dark Templar homeworld of Shakuras. Terran Emperor Mengsk I, 
            having achieved his goal of total power over the human colonies, must 
            now turn his attention to both the rising power of the woman he betrayed--Kerrigan, 
            the infamous Zerg Queen of Blades--and a conspiracy deep within his 
            own ranks. T he 
            United Earth Directorate, a force from the original Terran planet 
            is intent on bringing Arcturus Mengsk's empire back into their dominion. 
            The United Earth Directorate (UED), getting anxious about hostile 
            alien life in the galaxy, decides to do more than oversee the epic 
            battle between the three races. With the leadership of Admiral Gerard 
            Dugalle, they plan to to dispose of the Terrans, and use the Zerg 
            to their advantage to destroy the Protoss. With the reigning Overmind 
            destroyed, Kerrigan wants to take control of the Zerg broods. The 
            newly spawned Overmind won't be easily overcome, this Kerrigan must 
            scheme to overthrow it and take her place as ruler of the Zerg. The 
            game progress through the three campaigns with the Terran side being 
            played with the UED, and the order is altered: Protoss first, then 
            Terran, then Zerg.

			New Units and Upgrades--Each race has two new units and the Terrans and Zergs have upgraded units. Some
			of these new units and upgrades add balance, others create new strategic possibilities.
			
				- Terrans: There are two new units and an upgraded unit. New Terran units
				from the United Earth Directorate have more technology than the original Terrans. The two units are the Medic and
				a heavy missile frigate called the Valkyrie. The Medic are women who are highly skilled with three special abilities:
				Heal, Restoration (heals and removes special effects or spells on a unit), and Optic Flare (ultra-bright flash
				grenade). These Medics are great for restoring the health and vitality of wounded soldiers and for curing various
				Zerg infestations such as Parasite or Ensnare. For defense, the Medic use the A-13 Flash Grenade Launcher to discharge
				a maximum burst in the visible white light as well as ultra-violet spectrums. This has the effect of severely damaging
				the retinas or photo-optic receptors of any targeted unit. The Valkyrie Frigates are a powerful addition to the
				UED Fleet. The Valkyrie missiles are capable of reducing most conventional star fighters and airborne structures
				to rubble. Valkyries are heavily armored and can take substantial punishment from enemy fire before they suffer
				any failure. The Goliaths have been upgraded. They are much more useful and cost efficient now, with the necessary
				range to defend against Guardians.
 
 
- Zerg: There are two new units 
              and one upgrade. New Zerg units are the Lurker and the Devourer. 
              The Devourer is an acid-spewing assault flyer that can quickly overcome 
              enemy air units and are excellent for stopping Wraith or Scout rushes. 
              The venom of the Devourer consists of toxins that can eat through 
              any known substance, including the reinforced armor plating of the 
               Terran and 
              Protoss capital ships. The Lurker, a new Hydralish mutation, is 
              useless above ground but watch out when it burrows. Lurkers emit 
              waves of supra-dense spines against their enemies. Any warriors 
              on the surface who are caught by these spines are instantly impaled. 
              These spines are capable of tearing into flesh, steel, and even 
              reinforced armor plating. And the only way to see them is to fly 
              in a detector. They can easily take down Marines or Zealots. The 
              Ultralisk have been upgraded and given thicker armor and faster 
              movement. Terran and

- Protoss: There are two new units. New Protoss units are the Dark Templar
				and the Corsair. The Dark Templars were in the original game but could not be mass-produced. The Dark Templar warriors
				are able to bend light around themselves which renders them virtually invisible. Dark Templars can also merge to
				create Dark Archons, who wield impressive psychic powers. The Dark Archons don't have attack capabilities comparable
				to the Dark Templars but their three abilities: Feedback (used to drain enemy energy points), Mind Control (used
				to possess and manipulate opposing forces), and Maelstrom (nulls attack ability of organic units) are important
				weapons. Blizzard had done a good job of balancing the strength of the three races. Even though the Dark Templars
				have highly developed attack powers, they have not been made overpowering in comparison to the other two races.
				The Corsairs, air-to-air fighters, have the ability to block any form of attack on the air or on the ground. They
				can employ a disruption web to temporarily incapacitate ground forces and are good for dropping troops down from
				transports into an opponent's base.
			
Missions--The three new missions in Brood War contain complex 
            plots, with early missions being as difficult as the midgame missions 
            in the original. Scripted sequences and conditions provide interesting 
            twists. Some missions require deep gameplay and decisions made in 
            one battle will affect the number and type of units faced in the next. 
            There are multiple objectives for most of the conflicts and players 
            have the choice of targe ts. 
            The addition of new units for the missions does not have a negative 
            effect on the play balance achieved by Blizzard in the original StarCraft. 
            The equilibrium between the races is even better, and the story is 
            more complex. There is a large cast of characters that are believable 
            and interact in a convincing manner. Blizzard has improved Artificial 
            Intelligence on the opponents part. Improved AI and enhancements in 
            the game design create more interaction between the characters in 
            the game. For instance there are levels where allies will appear, 
            perform a vital

            of your base. This adds to the realism and the feeling that there 
            are many parties with their own agendas, which are decidedly different

			Maps--Maps vary dramatically from mission to mission, requiring careful offensive and defensive strategies.
			
          Graphics--The graphics in this Expansion Set are as good as 
            in the original. The three new tilesets: Twilight, Desert and Ice 
            World are excellent. Special effects such as the spectacular explosions 
            look extremely realistic. The tilesets enhance an d change the balance of power and add to the strategic 
            experience of the game. The twilight world of the Dark Protoss is 
            very atmospheric; the desert is similar to a nuclear wasteland; and 
            the ice world is like something from Star Wars. The 3D modeled buildings 
            are also great. There are not as many cinematics as in the original 
            game, but the new intro movie and ending cinematics for each of the 
            three campaigns are longer and more stylish. The animations are crisp 
            and smooth for a 2D game.

			Sound--The sound in Brood War is even better than in the original. There is new music, new sound effects,
			and new speech. Each of the three races gets a new music track, and surviving characters get many more speaking
			lines. All the new units in Brood War sound great and many of them have very amusing things to say if you keep
			on clicking. The dialogue used in mission briefings and during the in-game scripted events is convincing. The sounds
			help make the characters believable and they seem to have personalities.
			
			Documentation--There is a chart of the three races and the units, as well as a CD cover/booklet that has
			information on the new units.
