Tank

Detonation Pack. Commando explodes at the moment of death and wounds the enemy's nearby ground units. It is useful early into the game, when Commando are an important part of your army. Later into the game, as long as you keep building them, it is better to replace this upgrade with another one.

Autocannon. Avalanche may attack while in movement. It is useful if you utilize the tactic of mobile combat, or you often have to flee from the battlefield. Otherwise, you can ignore it, especially that Avalanche are siege units whose first purpose is to destroy buildings. They do not necessarily need to move, while doing that.

Target Acquisition. Predator fires in single shots, instead of in bursts. Without this upgrade, the unit uses up all of its ammo on a single target, even if it has been destroyed. This often leads to a situation, in which Predator wastes some of its ammo and has to wait until the weapon is reloaded. Therefore, if your army mainly consists of Predators, buy this upgrade. This will boost their effectiveness in the battlefield.

Artillery

Ground Assault. Cloudburst becomes capable of attacking ground targets. A situational upgrade. Cloudburst is a strong unit of low durability. If you have many of them, because of the enemy's air forces, buy this upgrade. Thanks to this, you will also be able to use the units against bases and ground forces. Otherwise, ignore it.

Long-range Ballistics. The Guardian's ground attack turns into a long-range artillery attack. Guardians are only used for stationary defense, Their range is lower than that of the enemy artillery, which makes them require backup, in combat against it. If you play a defensive game and/or your defenses would use a greater firepower, this upgrade is worth choosing. Otherwise, pick one of the remaining ones.

Platform stability. Hellstorm can attack while in movement. It is a useful upgrade, if you want to use the tactic of fighting in movement, and artillery is a big chunk of your army. It is especially useful while retreating, when Hellstorm can engage enemies outside of their reach. It is useless if you do not ensure artillery with backup, which makes it fight at short distance, much shorter than their minimal range.

Air

Air Canister. Commando may shoot into the targets up in the air. Select them, if it is them that your army relies on and you are dealing with an opponent that relies on air raids. Also, if you are not using Warbird jet planes, and you would use an additional unit that shoots airborne units. Otherwise, ignore this upgrade because you will not be building too many Commandos.

Incendiary Catalyst Bomb. Nimbus receives incendiary bombs that burst into flames for several moments, after the impact. It is a highly valuable upgrade, if you are using bombers. You lock on the incoming army, drop bombs onto the first lines and, if the rest of the army does not change its route, they walk into the flame trap. Also, it is valuable while bombarding buildings, especially turrets, because it allows you to destroy them faster. Useless, if you do not use bombers.

Explosive beacon. The Stratus buoys explode after they cease to function. After hitting the enemy unit, Stratus marks it with a signal buoy. The buoys are impossible to detect and they move along with the enemy unit. There is a chance that at the moment of explosion, the target will be among thick crowd, which increases the effectiveness of the bomb considerably. It is a useful upgrade that is worth buying, especially in a situation, in which you rely on air reconnaissance and you do not use bombers.

Stealth

Stealth sniper. Stalkers become invisible in movement. Stalker is a fast quite durable and strong unit, at least up to the moment, in which Predators start being used. Equipping it with invisibility and an additional weapon raises its effectiveness. Unfortunately, the necessity to stay in movement decreases its ability to set traps, but turns them into perfect scouts.

Mass cloaking. Seeker loses invisibility and ensures it to the nearby units, as long as it stays still. It is an immensely useful upgrade, for setting traps and hiding units where the opponent does not expect them. It requires some training, but it yields great effects, both in defense ad in offense. Check out if you are fully capable of using the possibilities it offers and if so, buy it without hesitating.

Cloaking sensors. Stratus starts detecting invisible units. Buy it if you often rely on airborne reconnaissance and the opponent often attacks you with invisible units. Otherwise, leave it out.

Economy

Auto repair. Hangar repairs airborne units that have been parked in it. Airborne units have low durability. Against strong AA defenses, in the best case scenario, only a half of them return to the base. Also, they are quite expensive, when compared to the other units, especially bombers. Therefore, if you rely on air forces and you want to curb your expenses, invest in this upgrade.

Armored casing. Upgrades the armoring of Harvesters. It may be useful if you often lose your harvesters. Also, if you need lots of resources and each unit that you lose means a catastrophe. Otherwise, it is useless, mainly because refineries produce harvesters for free and in the numbers that they need. You can also choose this one when no other upgrade is to your liking.

Defensive utility. Small Hubs receive additional armoring and heal the buildings attached to them. It is very useful, if you build small mining outposts or bases behind the enemy lines. This upgrade allows them to hold for longer, in case they are spotted. It is useless if you more often use Medium Hubs and Large Hub, especially later into the game.
