Tank

Bastion Volatility. Bastion enters rage mode, after it takes enough damage. It wounds everyone around and, in case of death, it explodes. After being enraged, the unit does not regenerate its health and cannot be healed. Buying this upgrade should depend on whether you use this unit. If so, and you have many of them, it is worth considering the upgrade. Especially for battles against big groups of opponents and against fortifications. Otherwise, ignore it.

Goo Splash. Projectiles of the Destructor also wound the units around the target. It is very good for fighting big groups of lightweight units. If you do not use Bastion, pick either this or the other upgrade.

Contagious Goo. Projectiles of the Destructor rebound off the target and wound the two closes opponents. Choosing this upgrade, or the above one, should depend on the situation. If the enemy has many lightweight units, choose Goo Splash. If he relies on the heavy ones, choose Contagious Goo.

Artillery

Symbiotic Pool. The pools resultant from the Crescent fire heal allied units. This upgrade is difficult to use. It requires you either to move your units manually, of fight the enemy face-to-face, when the targeted units are close to your troops. It is useful, but you may be unable to use this upgrade to its fullest.

Projectile Endurance. The blast area and the power of the blast, from the Crescent projectiles are decreased. The projectiles can no longer be shot down from the skies, by AA units. This is a contextual upgrade. If you have lots of artillery, their projectiles will, sooner or later, penetrate the enemy defenses and the upgrade becomes useless. Still, it is a good idea to consider buying it, if you have little artillery, or the enemy has strong AA defense, which shoots down all of your projectiles. However, keep in mind that damage dealt by Crescent is much lower then and the general combat value of this unit drops dramatically, in different situations.

Catalytic Barrage. Tempest may attack ground targets. It is highly useless upgrade. As artillery, Tempest has long range, but low firepower. Fighting even lightweight units takes lots of time, not to mention attacking buildings. Buy it only if you are not going to use the rest of the upgrades.

Air

Surveillance Virus. Airplanes hit by the Tempest reveal the area around them, for some time. A contextual upgrade. In order to use it effectively, you would have to hit the enemy vehicle once and let it go. You would have to do this with a single Tempest from an ambush, e.g. hidden in a forest. Strong AA defenses do not let any plane escape so, potential scouts will soon be eliminated. The only exception is the situation, in which the enemy has lots of aircraft and attacks you on a regular basis. In such a situation, it is worth knowing what the enemy units, returning to the base, see.

Goo Corruption. Hitting from a Tempest deals additional, temporary, damage. It is a useful upgrade that increases AA firepower. Worth buying.

Aerial Defence. Radiants can shoot down airborne units. Not too useful. Radiant is a scout of low firepower. In comparison with Tempest it is useless in dogfight, even if it attacks opponents while invisible. You can buy it if you have lots of these and you are unable to deal with enemy air raids. Otherwise, ignore it.

Stealth

Stealth Sensors. Radiant receives stealth detection. Buy it if the enemy uses invisible units. Otherwise, ignore it.

Veiled Surveillance. Radiant receives stealth. It is a very useful upgrade. You do not have airborne scouts, but the ones on the ground, equipped with invisibility, are capable of making up for that. Deploy several of them on hills and in bushes, and you will gain the upper hand over the opponent.

Enhanced Cloaking. Dwellers remain invisible also while moving. In spite of tat, they still need to stop to attack. If you use them frequently, buy this upgrade. Thanks to this, Dwellers can also be used for scouting, or even like offensive units. You simply need to send the hidden mines into the enemy base, thanks to which you avoid being detected, and deploy them at the factory exit points, so they can destroy freshly-produced enemy units. Still, if you use living mines, take one of the abovementioned technologies.

Economy

Advanced Mitosis. Dwellers, at the moment of dying, drop two Small Proteans. It is useful, if you use mobile mines. It allows you to replace your lost units. Especially useful for traps and destroying enemy bases, especially in combination with the Enhanced Cloaking technology. Ignore, if you do not use mines.

Catalytic Residue. If Small Protean, Large Protean or Mother Goo eats a unit, or a building of the enemy, the neighboring Goo units are healed. It is highly useful, but only if you use Mother Goo and Proteans in combat and for destroying bases. Especially that the Goo units have little health. This upgrade allows them to survive in the battlefield or longer, and it allows you to save up on new ones. Ignore it if you do not use Protean nor Mother Goo in combat.

Progenitor Conversion. If the Large Protean or Bastion dies, it drops a Small Protean. Large Proteans should be rarely used in battle, unlike Bastion. If you use the latter, this upgrade will allow you to replace your losses quickly. Buy it if you fight with Bastions. If you fight with Mother Goo, it is better to buy the previous upgrade. It is more useful, in the long run.
