Mission 13 - The Grotto | Goo campaign Grey Goo Guide

Last update: 11 May 2016

Primary objectives:

• Defeat Naiko and seize the Communication Array.

Secondary objectives:

Destroy 5 enemy outposts.

You start in the North-Eastern part of the map [1]. The entire area is criss-crossed with Beta fortifications that are guarded by small groups of units. The disadvantage here is that wherever you go, you run into the enemy. The advantage is that you are not going to be attacked too often.

At the beginning of the mission, move the Radiant eastwards of the Mother Goo. You will find the first enemy fortifications [2]. Destroy them with the Crescent. This will require you to fire at it for some time, but you have plenty of time. You note that the enemy is taking blows and not responding. The only exception are the single scouts, but they should not pose too much of a problem to you.

Follow the pattern - scouting with the Radiant and laying Crescent fire - and clear the immediate vicinity [3][4][5]. Seize the opportunity and learn the opponent's reactions - if, and when, the units leave turrets and whether they attack, after they leave, or maybe they stay still and so on. Along your path, create additional Crescents and several Destructors to protect you against enemy patrols. Do not approach too close to the enemy positions, or you will be attacked. Instead, destroy them from a safe distance.

At all costs, protect your Crescents. Also, develop the technology to provide Radiants with stealth. Thanks to this, they will be capable of revealing artillery targets without being engaged by turrets. If you encounter turrets defended by Guardians, dispatch more Crescents against them. Sooner or later, their projectiles will penetrate the enemy AA defenses.

After you have cleared the nearest vicinity of the enemy reinforcements, head Southwards. In the meantime, create another Mother Goo and keep it near the main army. The first Beta outpost [6] does not have any additional fortifications, but its factory keeps producing new units. Therefore, remember about the Destructor guardians for your army. Also, remember to form n additional air protection, in the form of Tempests. Quite quickly, the enemy starts dispatching bombers in your direction. One effective air raids is capable of eliminating the majority of your units, including artillery.

After you have destroyed the first outpost, seize the nearby deposit. Approach the thickets [7], and small reinforcements will appear there. For the units attacking from the South, you can wait near the Mother Goo, but it is much better o hide among the bushes to the south of the destroyed outpost. Gather the remaining forces there and create new Crescents and Destructors, and also prepare new Mother Goo. You can also develop new technologies.

Another outpost [8] can be found Southwards. It consists of a big factory and several attachments. Watch out for raids, approach it with the artillery and start your fire. If there are enemy units around, use the Destructors to eliminate them. If not, dispatch all your forces to destroying the base. After that, seize the deposit.

You find another outpost in the center of the map [9]. Eastwards of it, there are many turrets, and there are quite a few of them in the outpost itself. Again, use the Crescent. Also, reinforce AA defenses, because the frequency and the strength of air raids will intensify. If, in the previous battles, you have lost of your units, retreat and replace the losses. At this stage, you should have filled the limit of units to a half, at least. During the attacks, reinforcements should arrive in the nearby thickets [10].

After the battle, seize both of the deposits. Hide Tempests in the thickets [10], from where they will be defending your units against the enemy air raids.

The fourth outpost is in the South-Eastern part of the map [11]. There are two ways in which you can get there - over the path from the West, which is walled and protected with turrets, or from the North - it is a longer route, but devoid of any defenses. For this reason, it is easier to attack from the North. Eliminate the factory and seize the deposit. The Western fortifications can be destroyed, but leaving them intact should not be to your disadvantage.

At this point, you should have reached the limit of your population. From the fourth outpost, head North. Both of the paths are fortified so, clear the right one first, and then the left one. The enemy will be trying to shoot down your artillery projectiles so, make sure that you have, at least, 10 Crescents. Destroy the turrets and then the outpost itself [12]. The enemy attacks, at this point, should be weak, but keep several Destructors for defense. Also, remember about Tempests, because the fifth outpost produces airborne units.

From the ruins of the fifth outpost, head North. There is one fortification line and your main target here [13]. After you have destroyed the previous targets, the enemy's main base should pose no challenge to you. If you have sustained small losses, you can attack straight away. If not, replace your losses first. Remember to scout the area beforehand. In front of the base, there are thickets that are perfect for that purpose. If, however, you do not feel like scouting, you can launch the onslaught straight away. At this point, the enemy will not be able to fight back anyways.

Finally, direct the Mother Goo into the marked area.
