Walking juggernauts, Titans are colossal zombies who have become tanks for the zombie hordes. They lead the major assaults during Alpha Company, drawing fire from lesser zombies that follow underneath them. Titans have large, powerful claws that can decimate a group of marines in a single blow. Its attack not only hits the target marine, but also the marines in the target's vicinity. Enormous health and lack of armored type make Titans difficult to bring down with most weapons before they get in range.
One Titan will assault Alpha Company near the end of the 1st holdout. Later on, after Demeter is defeated, several more will attack, providing support for the zombie horde during the 2nd holdout. Finally, right before the battle with Perses, several will spawn as the team is fighting hordes of cloaked Seekers and other infested. Titans will sometimes be cloaked, so it is important to have some form of detection.
Titans are sometimes released in the Apollo Security Team Campaign during the battle with Deimos if the team fails to intercept him in time. Titans can also be found as part of the horde preceding Athena, and sometimes during the battle with Hades.
