Yes but the races work completely differently.
The race I have finished concepting completely are the Fidelis Secuutus (Loyal Followers) of the Legion (or just Legion). Which are a band of brainwashed humans. They work in strange ways. Their pyrotechnology is quite advanced, they have learned to use oil in magnificent ways and can set traps to set their enemies aflame. They also have great melee fighters.
The other race (which works like the flood from halo, somewhat like the locust from gears of war, and somewhat like the Zerg from Starcraft) which is the Grim Effervo (Grim Swarm). They are a mixture of undead and giant insects. They have a unit that, upon death, erupts into a mass of man-eating scarabs that devour human flesh to regain health, and harvest ore from the bodies of the deceased. However, once their host is dead (The unit that holds the scarabs is called a Catacomb Beetle), and the scarabs are without life support, they have an extremely short life span. Scarabs are also slow moving, so they must be deployed in a mass of enemy soldiers, or an enemy base to be effective.
Also, Catacomb Beetles are quite expensive, so they are hard to mass. But each one (triggered or killed) spreads 6 scarabs from its corpse. However, if a Legion player decides to get smart with you and move some archers into your base and kill the Catacomb Beetles there, the scarabs will only be able to feast on their flesh, and the money used to produce the Catacomb Beetles will be utterly wasted.
