Notes:
- The table shows the default names/icons of techs. Flavor entry is displayed if accompanied by a change to effects/requirements.
- If a tech has been available as a research option in the as part of the last choice then its (total) weight will be halved in the coming choice.
- The table denotes the base cost of a tech. Actual in-game tech cost will scale with the empire's size (number of colonized planets and population).
- To research techs of higher tiers it is first needed to acquire 6 techs of the preceding tier.
- Sorting the table by tiers will place all Starter tech at the top and Repeatable end-game tech at the bottom.
- Most icons also double as links. For more information about an unlocked effect (buildings, components, etc.) click on the accompanying icon.

Phase Disruptors | 16000 | 4 | Phase Disruptor
|
 Ion Disruptors
|
Base: 45
Modifiers
|
Extremely high-yield disruptors that fire quantum energy charges causing incredible damage to those unfortunate enough to get in their way. |
 |
Arc Emitters | 20000 | 4 | Arc Emitter
|
|
Base: 40
Modifiers
|
Powerful weapons that launch a lightning arc of chaotic energy at targets, which in part can ignore armor and shields. |
 |
Focused Arc Emitters | 24000 | 4 | Focused Arc Emitter
|
 Arc Emitters
|
Base: 35
Modifiers
|
These upgraded emitters are equipped with better focusing lenses, resulting in a more powerful energy discharge. |
 |
Plasma Throwers | 5000 | 2 | Plasma Thrower
|
Blue Lasers
|
Base: 75
Modifiers
|
Weapons that eject destructive balls of high-energy plasma at targets. These plasma projectiles are extremely effective at eating through ship armor. |
 |
Plasma Accelerators | 8000 | 3 | Plasma Accelerator
|
 Plasma Throwers
|
Base: 65
Modifiers
|
These new accelerators launch projectiles of high-energy plasma with improved containment fields. This results in less energy leakage as the projectile travels in space towards its target. |
 |
Plasma Cannons | 16000 | 4 | Plasma Cannon
|
 Plasma Accelerators
|
Base: 45
Modifiers
|
The latest in plasma weaponry, these cannons are fully militarized versions of the older, somewhat improvised plasma throwers. Their plasma projectiles are even deadlier. |
 |
Neutron Sweeping | 48000 | 5 |  Neutron Sweep colossus weapon
|
|
Base: 10
Modifiers
|
An accelerated plume of neutron radiation "paints" the planet surface, severely degrading most materials and directly destroying biological tissue. |
 |
Mining Drone Lasers | 5000 | 2 | Mining Drone Lasers
|
Analyzed Ancient Mining Drones debris
|
Using strong-focus lenses in combination with an oscillating firing frequence help create lasers strong enough to mine asteroids, or shoot down hostiles. | |
 |
Cloud Lightning Conduits | 6000 | 2 | Cloud Lightning
|
Analyzed Void Clouds debris
|
Void Clouds use the electrical charges generated by the dense gases that make up most of their core to release bolts of burning plasma. Using the same gas composition together with a specialized conduit allows for powerful lightning weaponry. | |
 |
Null Void Beam | 6000 | 2 | Null Void Beam
|
The Doorway event outcome
|
By harnessing the entropic nature of the Null Void, this beam can actually destroy energy. | |
 |
Extradimensional Weaponry | 48000 | 5 | Matter Disintegrator
|
Analyzed Extradimensional Invaders debris
|
Applying 5th-dimensional energy manipulation principles on lower dimensional planes allows for the creation of powerful energy weapons. | |
 |
Volatile Material Plants | 4000 | 2 |
|
 Industrial Base
|
Base: 170
Modifiers
|
Aside from the obvious safety concerns, the artificial creation of Volatile Motes is an extremely delicate and complicated process that requires highly specialized equipment. |
|
Mote Stabilization | 4000 | 2 |
|
|
Base: 170
Modifiers
|
Volatile Motes are fickle particles that are dangerous to work with. In order to safely harvest them without setting off a chain-reaction of explosions, energy fields must be used to stabilize the motes. |
 |
Omega Theory | 10000 | 3 | Omega Alignment |
|
Base: 60 | When a temporal paradox becomes tangled, a kind of consciousness arises, with its own needs, its own desires. This is what has occurred with the consciousness that some call the Worm-in-Waiting. If we can align ourselves with that consciousness, we might just achieve a kind of immortality. |
 |
Unusual Senses | 6000 | 1 |
|
Observation Insights situation
|
Nothing is more innovative than natural evolution. By studying how pre-FTL societies view their world, we have devised new methods of detecting uninvited ships. |
