The Mechanics Terminal is the upgrade from the Manufactory. It focuses mainly on Energy and Money cost for its units, now having the Sakata Spider and A28-Gladiator available.
The Mechanics Terminal allows for the construction of Sakata Spiders, a powerful unit capable of shredding most armored vehicles. And the A28-Gladiator, a powerful infantry destroying unit that also decimates air units and is the most missile resistant unit in the game.
The A28-Gladiator is the most advanced A-class android ever produced. It will decimate infantry, it will absorb incoming missile damage as if it were nothing, and bring down aircraft with its powerful weaponry. Beware of Hover Tanks and Jotunns.
The power of the Sakata Spider is its strength in decimating Armored Vehicles, it can annihilate Chronite armor and even pack a punch against special. But unlike Hover Tanks, they are not missile resistant.
