In Utter Darkness

"On a distant, shadowed world, the protoss will make their final stand. Their heroes will gather, their forces will be marshaled, and they will die bravely. But still, they will die. And my zerg... will be slaves... to the hybrid. All will bow before the power... of the Fallen One."

- The Overmind's vision of the battle.

In Utter Darkness is a mission in the protoss mini-campaign in StarCraft II: Wings of Liberty. It is a flashforward of the Overmind's vision as seen by Zeratul, and watched by Jim Raynor on board Hyperion.

Observing the Future
Zeratul witnessed the protoss gathered for a final stand against the Dark Voice, in a future where the Sarah Kerrigan was dead, the terrans had been consumed, and the Zerg Swarm fell under control of the Dark Voice. It was a vision from the Overmind channeled to Zeratul through the spirit of Tassadar.

The Last Stand
"Protoss brethren, heed me! The last twilight has fallen. The galaxy burns around us! The terrans have been consumed. We are all that stands against the shadow. But if we are to meet our end this day, then we will do so AS ONE! En Taro Tassadar!"

- Zeratul rallies the final protoss

The protoss gathered their remaining strength for a last stand against the Dark Voice's combined hybrid and zerg force. The besieged hoped to survive long enough to complete an archive intended to aid those who might arise after and challenge the Dark Voice. Many protoss heroes arrived with reinforcements but for all of their efforts, it was fruitless.

The protoss were ultimately wiped out. They were followed into extinction by the zerg, which were wiped out by hybrids using special abilities.

Gameplay
Players control a protoss army, including a number of heroes, besieged by hybrids and zerg on three sides. The main objective is to kill a certain number of enemy units. The target for casual and normal is 1500, 2000 for hard, and 2500 for brutal. After that, the mission continues until the protoss are wiped out.

Players also receive a benefit for defending the archive.

Gateway Wall
