The expansion to the greatest RTS has the best story ever developed in a video-game!
The voice of the dropships pilot is in fact the same with the one from Aliens...& other examples like the Hidralisk which looks very similar with an Alien.
The Zerg & Protoss,both have been created by the ancient Xel'Naga race.
The action takes place immediatelly after the events in the original Starcraft somewhere in the 25th or 27 th century in the vast distances of our Galaxy where the Zerg supreme leader,the Overmind has been defeated.Now the control over the rampant Zerg has been taken by the Cerebrates but the Overmind will be reborn,somehow ressurected.The story is fabulous,the best ever in any video game.In short summary,the Protoss escape through a warp gate from their invaded & destroyed world Aiur to the planet Shakuras(2Pac Shakur,lol!)home of the dark templar where they meet the matriarch Raszagal.They are also in conflict with the fellow Protoss-the executor of the Protoss is hunting Tassadar fro he has colaborated with the "fallen" dark templars...The Terrans fight themselves not only the Zerg-DuGalle's UED forces(United Earth Directorate-the name is similar with the UAC of Doom) are after Emperor Mengsk & the rebel Jim Raynor saves Mengsk or...something like that i don't remember it's complicated.& the Zerg also battle themselves-Kerrigans Zerg are in conflict with the rampant Zerg wich belonged to the Overmind.
Kerrigan,the Queen of Blades also colaborates first with the Terran,with Jim Raynor(her old Terran partner in battle) & Emperror Mengsk-the one who is responsible for Kerrigans crossover to the Zerg.She promises Mengsk that she will liberate his home world Korhal from the hands of DuGalles UED & then she colaberates with he Protoss & both races have fallen into her traps.She will later kidnap Raszagal in order to reach Zeratul(a dark templar)& promisses to free her only if he destoys the Overmind of Char,the planet of the Zerg(only the dark templars of Zeratul are capable of killing the Overmind).& so on,it's much more complicated than this.So:Terrans battling Terrans,Protoss battling Protoss,Zerg battling Zerg,Protoss colaborating with Terran,Protoss colaborating with Zerg,Terran colaborating with Zerg...it's unbeliveable.A soap opera at a cosmic scale!
Also,Samir Duran,a Terran fellow will prove to be a foe to them as he is on Kerrigans side.The end of the game is of astronomical EPIC proportions as everybody unites against Kerrigan to defeat her-the surviving Protoss of Artanis(a young Protoss commander) & Fenix(who has been killed by the Zerg & ressurected),DuGalles UED & emperror Mengsk's forces.& it's not enough to stop Kerrigan as she will defeat them all.That mission is extremely hard,dificult.The whole game is very hard,it's the only thing that prevents this excelent expansion from achieving a 10 rating.The music is flawless,the same soundtrack from the original game.The graphics are outstanding even nowadays.The sound effects are brilliant.The voice acting is perfect-hands down-best voice acting from any,every game in this world.The balance of the races is not anymore perfect like in the previous game-now the Protoss have a new unit called Dark Archon which is obtained by fusioning 2 Dark Templars.It has the abillity to control the minds from all 3 races so the Protoss are the best here as you can have all 3 races in 1.Control a drones & SCV's mind & voilla-you can build Protoss,Zerg & Terran buildings & units.Not fair.
In BroodWar we have new lands,territorys like the Twilight on planet Shakuras & the Desert on Korhal,along with the classic Badlands,Space Platforms,Ash world of Char & Jungles.At the campaign,the laboratory missions where the game becomes an RPG(my favourites) are not missing,as you have 1 at each race.
There are 6 new units,2 at each race:
The Terran Medic & Valkyrie(an air unit that damages only enemy air units),the Protoss Corsair(the equivalent of the Terran Valkyrie) & the Dark Archon & the Zerg Lurker(the upgraded Hidralisk) & the Guardian(the upgraded Mutalisk which damages only terain units.
Now you also have the Campaign Editor where you can create your own maps.
A hell of a game,a masterpiece-unsurpassed by any other RTS title,it's the best along with the original Starcraft.
I'm eagerly waiting for Starcraft 2 but it's obvious that the king shall not fall!
