Hero Units offer a varied experience in Halo Wars' multiplayer aspects, bringing leader specific powers into the fray. The Covenant have a leader for each faction (Prophet, Arbiter and Brute) while the UNSC leaders function differently. The powers of the UNSC vary greatly and are numerous as opposed to Covenant leader units. In the Halo Wars Demo, Captain Cutter is the only available hero unit for the UNSC and the Prophet of Regret is the only available hero unit for the Covenant.
