Mission 15 - The Aperture Device | Goo campaign Grey Goo Guide

Last update: 11 May 2016

1 � Starting point.

2 � The first Control Node.

3 � The second Control Node.

4 � The third Control Node.

5 � Saruk's base.

6 � Lucy's base.

7 � Aperture Device.

Primary objectives:

  • Seize and hold 3 Aperture Control Nodes.
  • Dispatch a Mother Goo to the Aperture Device.

Secondary objectives:

  • Defeat Saruk.
  • Defeat Lucy.

With the right approach, this is a very easy mission. Your task is to seize three key points and hold them for 5 minutes. In theory, you can do this at the very beginning of the mission. In practice, however, you will not be able to fight back the enemy forces/ Without proper preparations, do not even attempt doing that, or you will have to start over.

Start by seizing two deposits in the Southern part of the map. The two to the West [2] are being defended by three Beta turrets, the two next to them [3] and to the South [4], are devoid of any defenses. Especially the central deposits proves to be of value, which can be mined by several Mother Goos. Seize them all and ensure protection of several small groups of Tempests and Destructors.

There are many ways, in which to destroy both bases - Mission 15 - The Aperture Device - Goo campaign - Grey Goo - Game Guide and Walkthrough

There are many ways, in which to destroy both bases. The majority of them, however, require time. Which you do not have too much of. For as long as both of them are operational, the enemies are dispatching their teams and elite units. The Hand of Ruk, with the Alpha support is a challenge that you, rather, cannot stand up to. This is why you should gather a group of six, or more, Mother Goos, to the South of Saruk's base [5]. Reinforce them with several Destructors. Gather all these forces in one spot and have them attack the enemy fortifications. Mother Goos are not the strongest units in the world, but they are perfect for destroying fortifications, if acting in a group. Keep them close to each other and pick targets yourself, and the enemy wall will fall in no time at all. During the attack, you may lose one of the Mother Goos.

After you get into the base, ignore the fortifications to the East - Mission 15 - The Aperture Device - Goo campaign - Grey Goo - Game Guide and Walkthrough

After you get into the base, ignore the fortifications to the East. Head Northwards, while keeping to the left edge of the map. Along your path, you run into enemy units and single turrets. Destroy all that moves, up until you reach the HQ. Destroy all of the key buildings and Saruk ceases to be a problem. If, in the meantime, you receive a message of the Hand of Ruk, do not lose your head. The unit appears by the Aperture Device [7] so, go out to meet it. It attacks you with rockets, but this is its only offensive weapon, because the turrets are empty. Get to it with, at least, one Mother Goo, and the Hand of Ruk will be immobilized and, after some time, destroyed.

While destroying Saruks base, you should start producing two Purgers - Mission 15 - The Aperture Device - Goo campaign - Grey Goo - Game Guide and Walkthrough

While destroying Saruk's base, you should start producing two Purgers. If your population limit permits one only, gather all of the Bastions and Dwellers and dispatch them on a suicide attack on Lucy's base. Make haste, because an Alpha appears on the map soon and you will be unable to destroy it without the Purger support. With this type of unit, you will easily destroy Lucy's base. It is not even going to need any support, because, although Lucy's base is well defended, it is not defended well enough, to withstand an elite unit.

If the Alpha has not appeared so far, good for you - Mission 15 - The Aperture Device - Goo campaign - Grey Goo - Game Guide and Walkthrough

If the Alpha has not appeared so far, good for you. If it did, send a Purger against it. If you do not have any, or they are being produced, you will have to attack with the other units. Use the Bastion to distract the Alpha, and Destructors and Crescents to destroy it. Remember that the beam of the superunit can be dodged and approaching to close will result in an attack with a shockwave.

At this point, you should have the entire map under your control. Therefore, it is time to get prepared. For each Control Node you need one Mother Goo. You should also produce two Purgers. Fill the rest of the limit with Destructors and Crescents. You will defend the central and the Eastern Control Node [3][4] with single superunits. Deploy the rest of the armies by the Western point [2]. After you have deployed Mother Goos next to the Control Nodes, you need to defend them for five minutes. If any Mother Goo is destroyed, during that time, you need to start over.

To defense to start, you need to issue the patrol order. Without this, the Purger will take no action and will soon fall to the enemy. While patrolling the area, it will attack everything in sight. The enemy groups are highly concentrated so, a single attack destroys the entire group. In the worst case, one or two units survive it. This way, one Purger is enough to defend the entire Control Node.

After you issue the orders, save the game and near the Mother Goos to Control Nodes - Mission 15 - The Aperture Device - Goo campaign - Grey Goo - Game Guide and Walkthrough

After you issue the orders, save the game and near the Mother Goos to Control Nodes. Countdown does not start, for as long as Mother Goos are not near all three of them. From now on every, around, 30 seconds, you will be attacked by strong groups of enemy units. The Purger in the patrol mode, right next to the Control Node, is going to deal with them with flying colors so, the most difficult is the defense of the Western point [2]. Gather as many Destructors and Crescents there as possible. Ignore the AA units, the enemy is not going to use aircraft.

If you want your chances of victory to go up a bit, save the game before the countdown starts. During the attacks, take a mental note of where the units appear. There are several such spots and they are always the same. Remember their location, load the game, deploy an extra Mother Goo there, as well as the rest of the units, and see the enemy units being destroyed, right after they arrive. The only exception is the central Control Node [3], which is attacked from three different directions. After you deploy a Purger right next to the building, you will not be able to see where the enemy units come from. But, you do not really have to, because the superunit will deal with them, without any problems.

After the attack is over, you only need to send the Mother Goos to the marked location - Mission 15 - The Aperture Device - Goo campaign - Grey Goo - Game Guide and Walkthrough

After the attack is over, you only need to send the Mother Goos to the marked location. If you have destroyed both of the enemy bases, the last objective is pure formality.
