Biowar is a rare modification for the DOS version of Tiberian Dawn.
The modification adds four missions that replace the four last Nod missions. The mod also adds two new units the Chemical Tank, replacing the Flame tank, and the Heavy Tank (with the model of the Heavy tank from Red Alert 1), replacing the Light tank.
