The Nucleon is a close to mid-range (up to 500 meters, with an optimal range that is dependent on what overheating phase the weapon is in) heavy energy weapon. It has unlimited ammo, but its accuracy drops as it fires continuously because of its overheating mechanic. It has a light and medium counterpart (Quarker and Atomizer respectively).


The Nucleon is an energy machine gun without a reload time, so it can fire indefinitely, quickly dealing damage to enemies.

However, it does have a drawback. After 5 seconds of being continuously fired the projectile dispersion increases (essentially making the weapon less accurate from a distance), this is due to the weapon overheating mechanic, to the point of becoming wildly inaccurate when firing on full overheat, even when firing from closer than its maximum range of 500 meters. Firing must be discontinued for a certain amount of time (depending on how much overheat) to allow the weapon's heat to dissipate, thus allowing the Nucleon to fire with more accuracy. So it is important to fire in short bursts when engaging targets, to maximize its damage potential at a range near 500 meters.

At point-blank, it still remains effective even if it has overheated. It also does a poor job of destroying physical shields as it is an energy weapon, which can act as a counter to the Nucleon. Like other machine guns, you need to stay out of cover to do high damage. This exposes the robot to enemy fire and can be fatal to robots with low health or a lack of shielding. It can be used in long term firefights due to its unlimited ammo, but also effective with quick skirmishes. Robots with more health are advised using this weapon, like the falcon.

The damage per projectile is similar when compared to other medium machine guns like Tempest, but the firing rate is faster than the auto-cannons, and the perk of unlimited ammo makes it outshine the kinetic machine guns. It can quickly destroy enemies due to its quick bursts, and the unlimited ammo allows you to take out many enemies quickly without worrying about reloading.

Pros and Cons


  • Infinite ammo-never need to reload
  • Energy shells allow penetration of energy shields
  • Considerable damage in extended combat
  • Great at sustained fighting
  • 500-meter range allows mid-range shootdowns (when not overheated)
  • When brawling, all shells will hit target
  • when overheated, it can hit robots in stealth


  • Weapon overheats when continuously fired, making it lose accuracy
  • To maximize damage potential, robot needs to expose itself for a very long time
  • Very close optimal range when at full overheat
  • Ineffective against physical shields

ATTENTION: The table shows amount of damage according to in-game stats. The real DPS is unknown because the real fire rate is unknown. If somebody have the lvl 1 - lvl 3 Nucleon, you are welcome to edit the damage amount. Now it shows the damage before buff. The 1’s in the table are currently unknown, more stats will be added soon.

Accuracy By Distance/Overheat

Below is the average percentage (%) of projectiles that hit an enemy robot (if aimed directly at) at specific ranges, when not overheated (5 seconds or less of continuous firing) compared to being fully overheated (9 seconds or more of continuous firing).

Range Non-Overheat Accuracy % Max Overheat Accuracy %
50 meters or less 100% 100%
100 meters 100% 96%
150 meters 100% 44%
200 meters 100% 27%
250 meters 100% 18%
300 meters 100% 16%
350 meters 100% 7%
400 meters 100% 4%
450 meters 100% 2%
500 meters 100% 1%

Note: The numbers shown are based on an average-sized robot being targeted. Due to this, these percentages can be higher or lower depending on the size of the targeted robot.
