Likewise the Land Raider was limited to one per player. In the original Dawn of War game both sides could upgrade their tanks from anti-personnel to anti-tank (the Destructor pattern and Annihilator pattern, respectively). For example, Space Marine Predator tanks were limited to carrying anti-tank weapons while Chaos Predators were limited to anti-personnel weapons. Many of the units available in Dawn of War were simplified, reduced or limited for the Winter Assault expansion. In this campaign, at the beginning the player has a choice to either serve Disorder, whose factions are the Orks and Chaos Space Marines, or serve Order which at the beginning of the game is the Eldar and Imperial Guard with a few appearances of the Space Marines.

Although the Titan as a whole is not controllable, its weapon systems can be used to assist in the destruction of the Necrons, who make a cameo appearance in the final mission for each faction. All of the races and factions from Dawn of War (the Orks, Eldar, Chaos, and Space Marines) are available in addition to the new Imperial Guard, with each race trying to find and gain control of the Titan for their own reasons. There are two new single player campaigns, both of which involve each faction attempting to recover a lost Imperator-class Imperial Titan. Their infantry tends to be of lower quality than that of their opponents in terms of weapons, armour, and morale, but the Imperial Guard makes up for this with a range of powerful tanks, such as the Baneblade and Leman Russ, as well as the combat walkers called Sentinels, which until the Dark Crusade expansion were the only vehicular unit in the game which could uncapture strategic points. The Imperial Guard specialises in defence, and therefore has the strongest defensive structures of all the factions in the game. A new faction was included in Winter Assault, the Imperial Guard, previously only available in certain single-player missions of Dawn of War.
