At first a defense contractor, Essential Tech was the one behind the first successful counterattacks against the alien forces. As they were the only ones that seemed to capable to succeed, others soon joined, and this force became humanity's last hope.
Essence Hyperion Attack Craft and Athena Hypersonic Interceptor


Hyperion: Being heavy and bulky for an attack plane, it has a big power generator to generate plasma, used both for attack and to achieve flight.
Athena: Capable of achieving hypersonic flight, Athenas use lasers against ground targets, and against aiborne units a special kind of missiles, designed to combat Vintarid spacecrafts.
Essence Tartarus Subterrene and Icarus AMS


Tartarus: Fully autonomous, these machines melt through rock with ease, emitting very little noise and vibrations. Their tunneling speed also leaves conventional tunnel boring machines far behind.
Icarus: Basic AA unit for the Essence. Using a modified Hummer chassis and fully automated, which helps Essence a lot when dealing with some of Vintarid flying units.
Essence Base Defenses (including Smart Mines) and an EMP Drone


Base defenses: Essence has the most base defenses of all sides, allowing them to cover every need. This includes Autocannon, Laser Battery, Howitzer, and Smart Mines.
EMP Drone: Small tracked robots carrying a single-use EMP Bomb. Detonating the bomb completely fries the drone's circuits, making it one-time use only.
I should start working on Vintarids soon, since i neglected them a bit, and next update will probably be Vintarid-exclusive.
