The Final Stand at Jacinto Plateau
The last wall falls so that humanity may finally breathe again.
The Final Stand at Jacinto Plateau marks the climactic conclusion of the Locust War and the ultimate sacrifice required to save the planet Sera. Occurring during the events of Gears of War 3, this desperate defense represents humanity's last line against a merged threat of Locust remnants and the uncontrollable Lambent contagion. As the COG capital crumbles under a tidal wave of corruption, the surviving soldiers must secure the launch of a planetary weapon known as the Pendulum Bomb. This event signifies not just a military defeat, but a necessary evolution for the human race, forcing them to abandon their last sanctuary to ensure survival.

Lore & Background
By this stage in history, the Locust had been largely decimated, but their underground tunnels had become breeding grounds for the Lambent, a violent mutation caused by Imulsion exposure. The COG knew they could not hold Jacinto forever against such an apocalyptic force. The decision to deploy the Pendulum Bomb was controversial; it would destroy all Imulsion in Sera's core, killing the Lambent instantly but rendering the surface temporarily toxic and uninhabitable. The defense of the plateau became a race against time. While Delta Squad engaged Queen Myrrah within the Citadel to prevent her from stopping the launch, Baird prepared the weapon at the launch site outside the city walls. The fall of Jacinto was not merely a loss of territory but a symbolic end to an era of siege warfare, forcing humanity to scatter across the globe or seek new worlds.
In Their Own Story
The sky above the plateau burned with the violet hue of corrupted Imulsion. Marcus wiped grime from his visor, watching the Lambent swarm surge over the breach in the wall like a living tide. Behind him, the city lights flickered and died one by one as the ground shook under the weight of the coming wave. There was no retreat left, only the distant hum of Baird's machine powering up on the horizon. They had fought to keep this place alive for fourteen years, but now they had to let it die to save what remained.
Reader's Guide
The conflict begins as Delta Squad infiltrates the Locust Citadel beneath Jacinto to confront Queen Myrrah directly. While Marcus and Dom engage the Queen in her throne room, Baird races against time to activate the Pendulum Bomb at the launch site. Simultaneously, Anya Stroud coordinates the evacuation of civilians from the city walls as the Lambent breach expands rapidly. The defense becomes untenable when the Lambent Queen manifests, threatening to consume everything before the bomb can fire. Marcus defeats Myrrah, securing the path for Baird's launch sequence. As the Pendulum Bomb detonates deep within the planet's core, a shockwave of energy purges all Imulsion from Sera. Jacinto City collapses into ruin as the Lambent disintegrates instantly. The surviving members of Delta Squad escape aboard a transport vessel just as the city is consumed by the cleansing wave. This event marks the end of the Locust War and forces humanity to rebuild from the ashes without their last stronghold.
