An experimental SED model that can instantly travel short distances when being damage or approached by an enemy. 

Combat tactics
Quant has an energy shield that can be deactivated by shooting from the rifle Arcus. In this case, the boss will be immobilized for a few seconds. At this moment, you will have to approach it from the back and impact the robot in a certain way to deal it damage. To destroy Quant, you will need to repeat this action several times.

Scenario 2
The location consists of three halls. To move between them, you will need to use teleportation devices located in special rooms. Enemy soldiers will constantly arrive at the scene. By shooting illuminated panels near the doors, you will be able to temporarily block them and prevent the appearance of new enemies. 
In the last room, the boss will hide on a separate platform, which can be accessed only via a teleportation device. You can make your way to the teleport room with the whole squad or send one fighter to finish off Quantum while the rest of the team provides the cover.

The prototype of a giant-sized reactor operating on "dark energy". It is protected by a special laser unit connected to it.

Scenario 1
The location features one circular platform around the reactor. In the center, there are three energy converters, which must be destroyed in sequence by shooting from Arcus. The first converter will be protected by three laser emitters, the second one by four, the third one by twelve. Thus, the safe area between the lasers will decrease during the battle. At the second and the third stages of the fight, you will need to destroy the reactor rods rising from the platform avoiding charged capacitors.

Scenario 2
The location has a reactor in the center and 5 semicircular platforms at different heights along the walls. Despite the fact that you will be operating SEDs, you will be able to climb platforms only with the help of a teammate. On the first and the third platforms, you will need to destroy energy converters with shots from Arcus, and on the last fifth platform your objective will be to eliminate the core of the reactor. It is protected by an energy barrier that can be temporarily disabled by shots from grenade launchers that can be found within boxes nearby. Only after removing the barrier you will be able to damage the core.
All this time, you will be attacked by fighters arriving from different directions and laser emitters rotating around the reactor.

A heavy guard drone is another result of the experiments with "dark energy". It has several types of weapons and an energy shield.

Combat tactics
The boss becomes vulnerable after turning off the shield by firing at it from a grenade launcher - the drone has to expose its power core that is vulnerable to the Arcus rifle. You can find grenade launchers in boxes that will appear and disappear at certain intervals. It is also a good idea  to use boxes as a temporary shelter.

Scenario 1
The location is a spacious warehouse with five boxes-shelters. Only two of them are available at a time. The drone moves in a circle firing a machine gun. It switches to a rocket launcher when the shield is deactivated. From time to time, protective turrets appear next to the boss, and enemy soldiers arrive at the scene. There will be more of them after the drone has lost half of the hit points.

Scenario 2
At this stage, the location will become less spacious, and the drone will move along the far end of the room. There will be 4 box-shelters. Two of them at the rear of the hall will be always available, while two boxes in front will appear and disappear. The boss shoots three bursts of “sticky” shells, and when the shield is deactivated, it fires lethal blasts of energy. After each reloading of  the shield, the complexity of the battle will rise due to an increased number of opponents. You can turn off the shield only after two hits from the grenade launcher.
