• Burrow a Zergling at each Lock in order to capture it and to prevent stray enemy units from recapturing it.
  
• Zagara can get worn down by constant enemy reinforcements if you take too long on this mission, so it’s best to try to finish it as early as possible.
  
• Be aggressive with Zagara the Hero. Send her to cast Baneling Barrage and Hunter Killers to chip away at enemy defenses whenever you can.
  
• The Xel’naga Construct deals significant AoE damage, and will kill your Zerglings easily. Use Aberrations, Banelings or Scourge instead.
  

• You can expand using your first four Banelings along with 12-18 Zerglings.
  
• Aberrations should be a core unit in your anti-ground army. They are good at handling the constant smaller fights you’ll have to engage in and provide a good source of damage against Suppression Towers.
  
• Scourge can technically suicide into Suppression Towers, but you should try to avoid using suicide units just to clear Suppression Towers.
  
• Building forward Hatcheries will significantly reduce the time it takes for reinforcements to reach Aurana. Having forward Hatcheries already in place is recommended for dealing with the third and fourth Security Terminals.
  

• Aberrations should be your unit of choice on this mission as both Zerglings and Banelings are too frail for sustained combat. Zerglings are useless here - don’t even bother upgrading them.
  
• Zagara can defend the first Evacuation Ship by herself with the help of a few Aberrations. She can defend the second Evacuation Ship with slightly more Aberrations.
  
• For Evacuation Ships 3-5, set up Hatcheries, Spines, Spores, and Bile Launchers on-site in order to help with defense if your ally is not very strong defensively. You should not attempt to solo any of these Evacuation Ships purely with your army units, as Zagara lacks sustained defensive strength.
  
• Burrow your free Banelings near the Evacuation Ships, then Unburrow them should you need reinforcements.
  
• Have an Overseer follow Zagara from Evacuation Ship 2 and onwards in order to defend against cloaked Banshees.
  
• Banelings are the most effective way to kill both Blightbringer and the Eradicators, possibly in combination with Infested Drop - as the Bonuses deal massive AoE damage, Aberrations and Zerglings will suffer heavy casualties when attacking them, so you should avoid this if possible. If your ally can clear either of the bonuses more efficiently than you can, you should instead save your Banelings for defending Evacuation Ships.
  
• Rally your free Banelings to the expansion in order to have an easier time defending against enemy attack waves. Morph a few Scourge or Spore Crawlers against enemy air compositions.
  

• After you clear the middle of the map, build Hatcheries there in order to quickly reinforce your army.
  
• Because the waves on this map are so numerous, Bile Launchers are a good option for defending choke points.
• Morph a few near your forward Hatcheries in the middle of the map; this allows you to handle enemy waves that are too far from your main army. 6-10 Bile Launchers should be sufficient - supplement with additional Spore- or Spine Crawlers if necessary.
  
• While waiting for enemy waves to spawn, morph your Zerglings into Banelings. Banelings and Scourge deal with enemy waves much faster, which affords you additional leeway in setting up for the next wave. Replace your dead units with Zerglings or Scourge as soon as possible.
  

• Clear out as many of the Train defenders as possible with Zagara before you engage the Train with your Zerglings and Aberrations.
  
• Save your free Banelings for the more difficult Trains such as the double Train waves.
  
• Don’t run your Banelings into Trains; it’s never worth it.
  
• A somewhat risky strategy involves setting up forward Hatcheries and static defense in the large open area between the top and bottom Train tracks. Set up around 10 Bile Launchers and position them such that they can hit both the top and bottom tracks at the same time. This allows you to bombard the Train escorts very efficiently, as well as conserve your army of Zerglings and Aberrations for their sustained damage against the Trains. However, this base is at great risk from both stray units and the Train escorts if you are not careful. If you commit to this strategy, be ready to manage the defense of this outpost.
  
• Another possible location for setting up Bile Launchers is just to the left of the main base, above the cliffs. This is a much safer location for your defenses, but it means that you can only engage the Train escorts at a later timing.
  
• If you are not using Bile Launchers to clear out the Train escorts, try to engage them early on in order to give yourself additional time to re-max on Zerglings and destroy the Trains.
  

• The first wave can be taken care of with your free Banelings if you build your Baneling Nest quickly enough. Alternatively, there are a few delaying tactics you can use to stall out this first wave until Zagara spawns. These include tanking damage with buildings or kiting melee units with your Banelings or a drone.
  
• After you clear the second set of Void Shards, set up four forward Hatcheries to the top-left of this area for reinforcements.
  
• If your partner is in on the plan, try to refrain from destroying each set of Void Shards immediately. Doing so prevents the next set of Void Shards from spawning, thus allowing you to clear out that base without having to worry about their AoE attacks - they can deal massive damage to your Zerglings and Banelings.
  
• Use a Corruptor for the Corruption damage bonus before suiciding Scourge into each Pirate Ship.
  
• The initial force you send to assault the final base should consist mostly of Banelings and Scourge, in conjunction with Infested Drop and Mass Frenzy. Your following re-max should mainly consist of Zerglings and Scourge.
  
• You can cheese the mission by using Scourge to snipe each Void Shard. For regular missions, this is not very practical due to the number of Scourge you will need to produce in order to pull this tactic off, but all the same this is a useful strategy to keep in mind for difficult mutations.
  

• The third to fifth Void Slivers have a significant amount of defenses and Zagara will struggle to kill them all in a prolonged fight with Void Rifts constantly bringing in new units. Therefore you’ll want as many Banelings and Scourge as possible for each fight in order to end them decisively before the Void Rifts and Void Sliver abilities can kick in.
  
• A Baneling Barrage can instantly destroy a Void Rift or Death Grip Crystal.
  
• An army of mass Banelings or Scourge can suicide directly into any Void Sliver, instantaneously killing it. The final Void Sliver on the top-left corner of the map can most efficiently be destroyed by an entire army of Scourge. Position your Scourge on the outskirts of the map before suiciding all of them into the Void Sliver at once. This allows you to bypass all the base defenses along the way. You’ll need all of your non-drone supply available to pull this off, so make sure you don’t have any leftover Zerglings or Aberrations if you’re planning to end the game in this manner.
  
• Zagara has a hard time defending against the frequent attack waves past 20 minutes into the game. Try not to delay the mission unnecessarily.
  

• Temple of the Past is a prime map for Bile Launcher usage. It’s possible to opt for a fully defensive Zagara build on this map with Spines, Spores and Bile Launchers at each of the four Temple entrances you’re tasked with defending.
  
• If you set up Bile Launchers in the corners between two ramps, they are able to intercept enemy attack waves coming from both lanes. However, do not leave them defenseless as they can easily be destroyed by any tough enemies such as Hybrid who survive the bombardment.
  
• Have a few Scourge ready in time for the attacks from the top-right lane, so that the incoming transports and air Hybrid can be destroyed before they can land.
  
• It is useful to spread creep around the Temple, providing Zagara with additional movespeed in order to get around fast as well as allowing you to set up static defenses.
  

• Don’t be afraid to spend resources on Banelings/Scourge against every attack wave; you can afford it.
  
• Consider building Bile Launchers to defend your expansion, as all enemy waves will head there after about 10 minutes into the game.
  
• The units defending each Xenon Crystal can be handled by Zagara alone, while the rest of your army continues pushing into enemy bases.
  
• The Molten Salamander possesses an AoE fire attack that will rapidly kill your Zerglings. It is best to use Banelings, Scourge or Zagara’s abilities to take it out.
  

• If you can predict where enemy waves will spawn, you can park Banelings and Scourge over these spawn points.
  
• Pushing into the enemy base and taking a third expansion allows Zagara to keep up with Baneling and Scourge production in order easily destroy every wave. This can be accomplished by by casting Zagara’s Infested Drop at the right choke point at 10 minutes into the game just as two attack waves spawn at this location, and thereafter send your ground army to clear the base.
  
• Zagara’s Hunter Killers plus Mass Frenzy is sufficient for the first Shuttle wave. However, you will most likely need Scourge for all subsequent waves. As you morph the Scourge, rally them towards the Warp Conduit that the next set of Shuttles are headed towards.
  
• Prioritize the Scourge gas cost reduction upgrade. You will need lots of Scourge on this map.
  
• Control your Scourge and the rest of army separately. In sufficient numbers, Scourge can take down enemy Shuttles and their escorts all on their own, while the rest of your army continues pushing or defends against attack waves.
  
• Spore Crawlers are an excellent mineral dump in this mission, especially when placed around the Shuttle Launch Bays and Warp Conduits.
  
• Build forward Hatcheries in front of the central Warp Conduit in order to generate Creep and reinforce your troops directly in battle.
  
• If the last wave becomes overwhelming, use your Scourge to avoid enemy units and snipe the Shuttles.
  

• After you clear the first Void Thrasher, forward 2-4 Hatcheries in the middle of the map. This offers a prime reinforcement location to easily reach every possible base.
  
• Aberrations are generally more effective at killing Void Thrashers than Zerglings as they are more resilient to the Void Thrashers’ AoE attacks. Bring a few Aberrations when you assault each base.
  
• There’s no need for Scourge until the very final base as Hunter Killers are sufficient anti-air.
  
• The third and fourth sets of Void Thrashers should be assaulted with Infested Drop before you commit your troops.
  
• Your initial force that assaults the final base should consist of mostly Banelings and Scourge. The following re-max should consist of Zerglings and Scourge.
  
• If you’re facing enemy Zerg, it is worth being aware that there are many Lurkers on this map that may give you trouble.
• Try to clear them out using the AoE portion of Infested Drop, Banelings & Baneling Barrage, and Aberrations before you commit Zerglings.
