United Fronts is a single-player mod that combines the campaigns of the original Call of Duty and United Offensive expansion with community created maps to form one large continuous campaign. It adds several new weapons and replaces almost all of the original weapon models. The mod requires the United Offensive expansion in order to play.
Again, sorry for the background audio...but I think that Richard Benson (the fastes guitarist alive and a living metal encyclopedia) should be part of the mod as well...
