Z-Sec

Another recreation of the classic Doom zombie soldiers, this type is closer to the originals as these carry firearms. They are seemingly security guards possessed by evil spirits and slightly mutated by these; a cutscene shows a security guard being possessed by a ghostly skull, which causes his skin to turn white and his eyeballs to explode. Several of the Z-secs have no eyes, but are still able to "see" the player despite this.

The Z-secs are notable for their Artificial Intelligence (AI), which makes them fight like soldiers, meaning that they duck behind objects, occasionally popping out of hiding to take shots at the player and occasionally rush the player's position. Like most of Doom 3's monsters, headshots do more damage than regular body shots.

There are three types of Z-secs:


 * Pistol Man: Bald guy with no helmet, armed with a pistol. Is capable of dodging by rolling sideways, always retalliating after a successful dodge. Takes around four pistol bullets to the body to kill.


 * Shotgun Guy: Similar to the classic Doom Shotgun Guy, but he wears a helmet with a broken visor over the eyes and is tougher. Slightly tougher than the Pistol variant.


 * Machinegunner: Wears a closed helmet with an intact, but bloodspattered visor and a breather, ultimately obscuring his entire face. Aside from the usual combat behavior of ducking behind objects, these zombies sometimes rush you while firing their machinegun. Toughest of the three Z-secs.
