"I have two hundred armed security personnel... Every entrance is covered! Even if you do get in, you won't get far."
Hans Tiedemann to Isaac Clarke.

The Titan Station Security Enforcement Guard was the primary law and security enforcement agency on the Sprawl, effectively serving as a localized gendarmerie. The Sprawl security officers took their orders directly from Director Tiedemann and it could be assumed that the entirety of the Security Enforcement Guard was under federal control.

The Sprawl security officers were equipped with a wide assortment of military-grade weaponry including the standard-issue SWS Motorized Pulse Rifle, Divet pistol, Seeker Rifle and Detonator. The security personnel also made use of more makeshift weaponry such as Flamethrowers and Line Guns as the situation dictated.

In the way of personal protection, the security officers were normally equipped with ballistic "hard armor", colored blue in accordance with their role as Law Enforcement, worn over tan fatigues and bloused black combat boots. Protective equipment included a head-enclosing, visored combat helmet, a collared ballistic vest, brassards, cuisses, poleyns, greaves and spaulders. As demonstrated at the entrance to the Government Sector, the Security Enforcement Guard also had access to armored Riot Shields and despite not being seen worn, specific Riot Gear existed for Riot Control officers. Other and specialized kits included the Security Suit, a more heavily armored alternative to the standard security officer's gear, the Elite Security Suit, an armored outfit designed for use by SWAT personnel and the Patrol Suit which was presumably meant for wear by officers on patrol in hazardous or (judging by the bright coloring) dimly-lit areas.

Additionally, the Security Enforcement Guard had ready access to aerial support vehicles such as the Gunship, used for targeted strikes against high-priority targets or for close air support of ground personnel.

Similarly to Marines of the Earth Defense Force, security officers also had access to Stasis and Kinesis modules, allowing versatility in the field.

Encounters with Isaac[]

Interaction between Isaac Clarke and officers of the Security Enforcement Guard was extremely limited with most of the security personnel encountered dead or near death. Although there was a standing order to kill Isaac on sight, the severity of the Necromorph outbreak took its toll. The security force was ultimately unable to carry out this order directly due to a lack of resources and/or manpower, instead resorting to impeding Isaac's progress or attempting to kill him with limited targeted strikes via gunships or other means.

The only direct encounters that Isaac had with live security personnel ultimately resulted in Security Enforcement Guard casualties. Throughout the course of the game, it was hinted that the security force was attempting to control the Necromorph outbreak with extremely limited success. As there were only 200 armed personnel left with Director Tiedemann in the Government Sector by the end of the game, it could be assumed that a vast majority of the Security Enforcement Guard was killed prior to the governmental evacuation. With the Sector's destruction, it was assumed that most of the security personnel were killed; however, as evacuations saw success in the early stages of the outbreak, small numbers of security personnel may have escaped along with civilians. Among the survivors was Sergeant Gabe Weller, who deserted and disobeyed Tiedemann's orders in order to save his wife's life.

The player encountered live Sprawl security officers in Chapter 1 and Chapter 13.

Known Officers[]


The Sprawl security officers differed from those in the single-player in that they functioned simply as less unique/powerful versions of Isaac Clarke, down to having exactly the same Security Suit over the single-visor equivalent worn by the single-player versions. Constantly equipped with a Pulse Rifle and a spare makeshift weapon, these officers basically carried out the orders of Tiedemann.

It was worth noting that the dialogue throughout the multiplayer did not actually specify whether the officers were actually privy to Tiedemann's plans or if they were just given a vague idea.

The multiplayer in Dead Space 2 saw players guide these officers through a variety of situations quite relevant to the single-player plot, most of which are at least mentioned in the single-player campaign if not directly affecting it. Through the sequences in the single-player campaign, it was possible to establish whether or not specific instances of the multiplayer situations were successful (for example, the Solar Array).


  • The Sprawl Security Suit that Isaac wore throughout the campaign was noticeably different from NPC suits and exactly the same suit was also the only one available for Multiplayer.
    • It's possible that the suit Isaac wears is a variant that is more equipped for operations in space rather than day-to-day operations around the Sprawl.
  • Security officers throughout the single-player are always seen to wield Pulse Rifles.
  • Security officers corpses, on occasion, relinquish items when stomped.
  • The Riot Team Isaac encounters during Chapter 13 wield Pulse Rifles sporting only one laser sight.
    • If you aim your weapon at the security personnel in Chapter 13, they will immediately open fire.
    • If Isaac is out of sight, but has not yet entered the adjacent restrooms, the security officers will launch a grenade from their Pulse Rifles. They shout: "Fire in the hole!" before doing so. Their grenades are the same as the alt fire for the Flamethrower.
  • During the charge of thousands of Necromorphs into the Government Sector, if one stands close to the window and rotates the view correctly, it is possible to see that the Necromorphs simply charge straight through the riot officers without striking them. As each officer dies during the sequence, their model just stops moving and their laser sight goes out. This is most noticeable after the charge if one rotates the view to see that the charge has ended but the riot shields and officers are still there, without their indicative laser sight and with no movement.
  • The New Horizons Security Force in Dead Space 3 are seen with the same body armor, but with a lighter shade of blue on the metal and small additions of yellow with a black visor along with more logos on the armor.
  • Based on every appearance of dead guards throughout the course of Dead Space 2, it appears that during the outbreak, security team members would often operate in small groups of two to three men, rarely being seen in large groups. 
    • This tendency to patrol almost exclusively in small groups may have been a serious contributing factor to the loss of majority of the Titan Station's active units. While they may have had Pulse Rifles, they would not have been able to effectively defend themselves against masses of Necromorphs as they would not have had the experience fighting them like Isaac.
    • The largest assortment of security members besides within the Government Sector is the start of Chapter 6 as Isaac begins to exit the Cassini Towers. Counting all soldiers in the hallways, lobbies, and just outside by the transit station, there are more men in this squad than there were in Gabe Weller's crew during the Severed DLC. This may indicate a more serious, yet failed, effort to locate and capture Isaac as he would still have been making his way through the Titan Station Church of Unitology at the time. This can be concluded due to one of the soldiers' RIG playing Tiedmann's message to fall back to the Government Sector, meaning the deaths were recent.
