"The Q-Beam fires a concentrated beam of unstable particles that eventually cause a target to explode."

- Inventory description

The TS-QPB-S11 Quasiparticle Beam Emitter, also known as the Q-Beam, is an experimental weapon found on Talos I during Prey (2017) and on Pytheas during Prey: Mooncrash.

Overview Edit

The Q-Beam is a prototype directed energy weapon. A stream of volatile quasiparticles causes rapidly cascading excitation in energetic systems of matter to the point of rupture. Each triad of Q-Beam cells it uses as ammunition contains 100 units of energy by default, though this number can be increased with firing time upgrades.

The weapon can be found :

Judging by a memo found by Morgan Yu, it seems that Transtar was secretly working on a way to weaponize the Q-beam and implement it in Military Operators.

Usage Edit

The Q-Beam fires a continuous, laser-like beam and does not do damage in the conventional sense. Instead, constant fire will rapidly fill in an entity's health bar in green, starting from the left and moving right. If the whole red or blue part of their health bar is turned green, the enemy will instantly die. This is with done with respect to damage already inflicted (ie, a damaged enemy will not require the empty part of their health bar to be filled up) and stacks with conventional damage: effectively, the green part of the entity's health bar does not exist, and the player will only have to deplete the red or blue part. If an enemy is not killed by Q-Beam fire, the green part of their bar will "heal" after a while, potentially leaving them with just as much health as they started with. If HUD is turned off, the amount of green in the health bar can be estimated by looking at the density or opacity of the shimmering green aura that becomes more visible the more quasiparticles are fired at the entity.

The greatest shortcoming of the Q-Beam is that since it does not inflict damage, it also does not inflict any sort of stun effect and enemies are free to retaliate as they like: worse, while firing Morgan's movement is slowed drastically. Thus, to be effective, it must be combined with a stun ability (e.g. the Disruptor Stun Gun or GLOO Cannon) or other incapacitating ability (such as Psychoshock, which prevents most enemies from using ranged attacks). As a tech weapon, it will also be temporarily disabled by electrical element attacks such as those of a Voltaic Phantom or Technopath.

The beam has high DPS when used effectively, making it ideal for taking out tougher enemies that require you to be far away to be safe such as the Telepath, Technopath, Weaver and Nightmare.

The effective range is no more than 30 meters. "Firing time" affects the rate at which the Q-beam actually uses ammunition, with the final upgrade effectively halving its base ammo consumption. Q-Beam Power provides an abstract measurement of the damage output (as it is measured in kilowatts instead of damage). "Handling" is the percentage of normal walking speed Morgan can move at when firing the Q-Beam, and can be improved with the "Heavy Gear Optimizer CRU" chipset.

Ammunition for the Q-Beam is rare and it benefits hugely from equipping the chipset CELL REFURB 00Q-X1, which will cause about 100 Q-Beam ammo to be dropped by every destroyed Operator and Turret. The effect is retroactive: any Operator or Turret the player has destroyed before acquiring the chipset can be searched again to find Q-Beam ammo.

The fabrication plan for Q-Beam cells (and for the Q-Beam itself) is the reward for completing the side-mission The Blackbox Project.

Weapon UpgradesEdit

The Q-Beam is a "non-standard tech weapon" and therefore requires Lab Tech I and II neuromods to fully upgrade with weapon upgrade kits.

Variants (Pytheas) Edit

Standard Q-Beam Edit

On Pytheas, standard Q-Beams are more effective than the basic stock ones, and can be found in various locations, as can their fabrication plans. Their background color in the inventory is green, and their built-in upgrades are randomized.

Advanced Q-Beam Edit

On Pytheas, advanced Q-Beams are more effective than the standard ones, and can be found in various locations, as can their fabrication plans. Their background color in the inventory is blue, and their built-in upgrades are randomized.

Trivia Edit

  • Contrary to the game design, Quasiparticles cannot propagate in vacuum because it's an emergent behavior of the surrounding medium (for example, phonons, the quanta of sound, are the vibration modes of the excited atoms) and thus cannot exist without a medium.
