Evolutions is a "Halo Wars" style mod for Command and Conquer 3: Tiberium Wars that features epic ground and air warfare on a massive scale.

The Covenant Barracks is home to the Well-trained and numerous infantry of the Covenant Forces. Grunts lead by Elites, Jackals, and Hunters are trained here. The different races are housed separately according to their status in the caste system. Grunts, the lowest of the caste system performs many of the more demeaning tasks. The lone Jackals tend to only socialize amongst themselves, while the solitary Hunters communicate with each other via their collective consciousness.
