Bio War

A modification of the original Tiberian Dawn that adds a four-mission mini-campaign replacing the final four Nod missions. In it, the player takes on the role of a Nod Commander facing off against the Bio Defence Initiative, a corrupted version of the GDI that employs biological warfare, notably using Visceroids.

The mod adds two new units: the Chemical Tank (replacing the Flame Tank) and the Heavy Tank (replacing the Light Tank, using the model from the Heavy Tank in Red Alert).
