Units | The Goo Grey Goo Guide
Last update: 11 May 2016
This race has only two units that are capable of shooting in movement - the scouting Drover and the AA Tempest. There are no technologies to change it. Additionally, the two basic units - Drover and Strider, cannot be upgraded in any way. For this reason, your army will have to be stationary and fight on positions chosen beforehand and, rather, not retreat, because this will turn out to be disadvantageous.
Apart from that, there are only six regular combat units. Dweller is a mobile mine. Once it buries into the ground, it activates stealth and, after being stepped on by the opponent, it explodes and deals considerable damage. Bastion is a blocking unit that may encourage the enemy to attack it. Both of them may be upgraded, thanks to which they get stronger in combat and turn into Protean, after they are destroyed. Thanks to this, even suicide units may prove useful to you, by first weakening the enemy and then, by letting the Protean finish him off.
Out of the remaining six units, Destructor is noteworthy. Thanks to upgrades, it is capable of engaging multiple targets. Also, there is Crescent. It fires artillery projectiles that can be destroyed in mid-air, but they leave a dark pool on the ground, on impact. All of the units near the pool, take damage for some time. This makes Crescent especially useful against moving targets. You only need to lay fire on the front units and see the rest of them take damage, as they walk into the contaminated area. The unit is also highly effective in narrow passages. Use it to fire at the columns of the enemy troops. This way, you make him choose - either split the forces, which weakens them, or head onwards, and take damage on the contaminated grounds. This is a choice difficult to make, if there are your forces in the passage.
Also this race lacks any airborne units, which makes it impossible to, e.g. scout the area from above. On the other hand, your main strength lies in numbers, the capability of fighting with the help from the highly flexible Mother Goo and regeneration. Goo is the only race whose units do not need any technologies for fixing, nor specialist buildings. You simply need to leave them alone for some time to have them get back to full health. The only exception is Purger, the Goo superunit.
Purger is the weakest elite unit. It cannot engage airborne units, is inferior to others, in terms of range and the attacking area is not too wide either. On the other hand, it has the most health points and it can be used as a target for the enemy and divert its attention from the rest. Apart from that, it heals Mother Goo and attacks the enemy units, provided they are sufficiently close. In case of being surrounded, it can simply change positions, instead of firing the primary weapon. Which it is not going to be able to use, due to the predetermined minimal range.
