If you haven’t downloaded the StarCraft II Gameplay Preview Video (the smaller 720 x 404 version is a whopping 268MB by the way), never fear! We at Space Invaded got it covered. Literally. Read on to see a blow-by-blow description of what happens.

The whole preview is very Protoss-centric, with the narrator starting with a disclaimer that “nothing here is final.” We’re introduced once again to the Zealots, the Protoss basic unit. They now feature the Charge ability, which lets them close the distance quickly with enemies so that they can unleash their powerful melee attacks.

After annihilating a group of marines, the Zealots are in turn wiped out by Siege Tanks, the classic Terran unit known for long range and extreme hurt. Here’s where a new unit, the Immortal, comes in. These ranged attackers have a special shield that activates when it receives a powerful attack, minimizing its damage. The Immortals use this ability to survive the siege tanks’ barrage and destroy them all.

Then, we’re introduced to a new Terran unit, the Reaper. Reapers have jet packs to go up and down cliffs, and carry two pistols. Since they do weak damage, they’re able to punch through the Immortals shields and win the battle. The Reapers then jump their way to the Protoss base, and destroy a pylon to disable the photon cannons. The Protoss then bring in a Phase Prism, a new unit that can turn into a mobile pylon, returning power back to the photon cannons. The Reapers retreat.

Now a new “Dark Dragoon,” called the Stalker makes it debut. It’s special ability, Blink, lets it instantly teleport to anywhere it sees. This is used to pursue the faster Reapers (by teleporting beside them when they’re out of weapons range) to kill them all.

Then, we see the new version of the Nydus Canal, which is literally a worm exploding out of the ground to provide easy access for Zerglings to ambush the Stalkers. The Stalkers use their Blink to try and escape, but there are just too many Zerg, who rush to attack a line of Zealots.

From behind the Protoss lines come the Colossus. These gigantic robots have long legs that let them go up and down cliffs (just like the Reapers), and feature a powerful and sweeping ground laser perfect against the numerous Zerglings. The Protoss win the battle.

Then, pushing forward, the group of Zealots of Colossi encounter a group of Zerglings, who immediately mutate into Banelings. Once the mutation is complete, the Zerglings are now a relentlessly rolling suicidal swarm. They wipe out the entire Protoss group, except for a single Colossus who manages to walk up a cliff and escape certain death.

That is, until a group of Mutalisks show up and destroy it. The Protoss send their Phoenix, light spacecraft that feature the Overload ability. When activated, Overload causes the Phoenix to shoot all of its weapons at nearby enemies, causing lots of damage in a short amount of time. Problem is, after such an attack, the Phoenix is temporarily deactivated, becoming vulnerable.

But through Overload, the group of Phoenix destroy the Mutalisks, and push forward. Eventually, it’s shown how they don’t have enough firepower against larger ships like the Terran Battlecruiser. A group of Warp Rays come to the rescue, using their ability to do more damage the longer they fire to cut through the Battlecrusier’s thick armor. When pushing forward however, they encounter a group of marines who use their numbers to negate the Warp Rays’ slowly but surely approach. The Terrans then fortify their position with missile turrets.

Here’s where Blizzard shows off the ultimate Protoss weapon: The Mothership. Essentially a flying space station with powerful shields and weapons, it’s good that the Protoss can only have one of these at a time, and build it at great cost.

Yet the Mothership is well worth its cost, as demonstrated when it activates its Time Bomb ability. It creates a field that keeps incoming projectiles from hitting the ship. This lets the mothership destroy all the anti-air defenses in the area.

But that’s not all. When the Mothership moves towards a Terran base, it unleashes its Planet Cracker ability, which deals instant death to anything on the ground underneath the ship. When the Terrans try using Battlecruisers to dispatch the Mothership, it activates its Black Hole ability. Which of course sucks all enemy ships into non-existence.

The Mothership, having annihilated everything in its path, pushes forward and encounters a large group of Terrans. Protoss support units appear from nowhere and the battle that makes up the last part of the video is joined. After a few seconds of virtual mayhem, three nukes destroy everything. Three ghosts reveal themselves, and are instantly ambushed by Zerglings. After the ghosts are killed, the Zerglings maneuver themselves into formation, spelling out “GG” (good game) as they mutate into Banelings.

That’s all folks! Remember, nothing in the demo is final!
