As in the previous games in the series, this title features the main characters of the Command and Conquer series, including the United States military leader, Adderly Fannin, and her military aide, Joes Plummer, who served as a squad leader during the initial attack on Tiberia. As in previous games, players can choose different factions to play as, with each faction featuring several historically accurate military units and weaponry, like the German Tiger tank, or the Japanese samurai unit. Command and Conquer 3: Tiberium Wars does feature some original inventions like a new mode (heading) that allows the player to choose various alternate future goals for the game, as well as a new supply unit, which allows players to build three times more resources than usual for all sides involved in the game. These resources can be used to research new weapons and tactics for use against your enemies, as well as providing a countermeasure if your enemy successfully captures a vital object.
For the most part, this game features a typical base building game play, where players must capture the needed objects and structures to progress to the next level. Unlike previous Command and Conquer titles, the player will have a limited number of buildings available at any given time and must construct these structures by sending platoons into battle. Once a Plunkett unit is damaged or destroyed, it will not be able to be repaired, making it a better idea to send your best troops to the battle, unless you want to waste resources repairing them. Although historically accurate, the graphics are quite simplistic, with most units having the same appearance. The multiplayer portion of Command and Conquer 3: Tiberium Wars features both text and voice chat, as well as the ability to use special commands to direct your units. This feature takes the game to the next level, as players can now call in superior units from anywhere on the map.
