The Siege of the Slab was a minor skirmish that preceded the Lightmass Offensive. A small group of Drones and Wretches assaulted the Jacinto Maximum Security Prison as the main Locust force advanced on Ephyra, causing the prison to be evacuated by a Gear platoon after a brief defense by the warders and inmates.

Order of BattleEdit

Defending the SlabEdit

As the Locust began a push against the Coalition of Ordered Governments' remaining territory in Gale 14 A.E., the baby Corpsers began to emerge from the bathroom pipes of the Jacinto Maximum Security Prison. An imprisoned Gear named Marcus Fenix began organizing a defense of the prison, directing the prisoners to smash the Corpsers with torn off pipes. Marcus told Officer Nikolai Jarvi to contact Col.Victor Hoffman and inform him about the situation in case it was the precursor to more attacks and request that the prison should be evacuated. After the CIC was informed, Jarvi armed Marcus and Millton Reeve with weapons since they were better shots than the warders. As the inmates secured the numerous pipes and vents around the prison, Edouain led a group in setting a boiling water tank up to kill the Wretches attempting to enter through an abandoned escape tunnel that the prisoners are working on. However, more Wretches entered the prison from another point. Marcus and Reeve led the effort to defend the main wing from the Locust creatures, but had little ammo to do so.[1] In between the waves of Wretches and Corpsers, Marcus sent all of the warders and inmates to Cell Block A which was the most defensible position while he and Reeve went to locate and plug the hole that the Wretches are coming through.[2]


The inmates and warders made it safely to Cell Block A and were extracted by a Gear platoon under the command of Lt.Schachter, but the two inmates are killed before being rescued. When it was discovered that Marcus was not among those rescued, Schacter demanded that Hoffman should let her go back to the Slab and rescue him, but Hoffman refused due to a battalion of Locust Drones now surrounding the prison. Marcus and Reeve encountered the Drones in the depths of the prison and managed to kill several before being trapped in a room with several cells and an elevator shaft that led to the surface, but also had Locust climbing up from the bottom. The shaft was too small for Marcus to climb up, but Reeve was able to. After he secured Marcus in a locked cell to keep him safe until he got help to rescue him, Reeve began climbing up the shaft, but was never heard from again. Marcus was rescued hours later by Pvt.Dominic Santiago as the Lightmass Offensive got underway.[3]
