Critical Elements: Chapter 2, Seeds of Chaos

Dragoon Siege
Three waves of Dragoons will attack from the north. Each wave will increase in force as they come. Defend against it with sunken defenses, starting hydras, and Defilers with Dark Swarm. Researching Consume, and feeding your Defilers will keep your defilers ready to cast their spell.

Counter-attack
This can be done later, however, the vulnerability of the northern base (blue Protoss) after their Dragoon attacks opens a chance for a counter-attack you might want to consider.

Attacking now will severely weaken this faction. Use your standing hydras, zerglings, and defilers to beat them.

Pesky Skirmishers
Save your mutalisks for quick response against skirmishers. Prioritize Reavers to avoid losing your defense structures.

Walls of Defense
Since your maximum Underling limit is capped, use Sunkens and Spore Colonies to defend the hive clusters.

Southern base, close to the Akilae (teal) can benefit from sunken colonies.

Critical Moment After Dragoon Siege
The Akilae tribe (teal) might be tempted to run you down with superior and massed air units right after the Dragoon Siege. Quickly dispatch scourges, or a squad of hydra with Dark Swarm support.

High Templar Psi Storm assaults can be held off by producing Queens and assigning pairs of Zerglings to patrol the bridges leading to their base.

Defeating the north-eastern base (purple)
Once, the northern (blue) base is defeated, send air units, probably some Guardians and Mutalisks to destroy their Temple.

Defeating the Akilae (teal)
As the strongest fighting force of the Protoss, the Akilae will have to be dealt with in good measure.

Defiler's Plague ability will soften entry for your Ultralisks. Ultralisks will serve to exhaust the Akilae's Psionic Storm casters. With a few hydras, Zerglings, and scourges, disrupt the Akilae to send their fleet, and take the battle on high ground (south-west base).

Send scourges, probably two control groups, and at least 6 control groups of mutalisks from the flank.

After they fall so quickly, move in to destroy their Stasis cells.

Remember to exhaust High Templar mana.

Amassing the Broods
The key is to utilize the Overlord control mechanic. Send squads to a hive cluster and take your overlord away. This will free up your Underling cap, and allow you to stack units.
