This is Evolution of the Swarm, a custom campaign by CybrosX, which follows Abathur after the events of Legacy of the Void. Command your army as Abathur, a zerg evolution master known for adapting to the most unyielding surroundings. Collect biomass from slain enemies to improve your minions. As you unleash monstrosities like the Brutalisk and Leviathan or control deadly strains of zerg like Guardians, Roaches, and Ravagers, you evolve ever stronger. Abathur is the future of the Swarm. After Kerrigan became a Xel'Naga, Zagara assumed the position of Queen over the Swarm. Zagara was powerful, more so than before, but not powerful enough to control her myriad of subjects and brood mothers who openly resisted and revolted against her rule.
