Ever since the game started, there have been many prototype weapons and robots that were tested by Pixonic, some of which never even made onto the Test Server. This page contains information on the known cancelled robots, weapons and other game features. The little information on this page cannot be found on Pixonic's website.

If you are interested in the topic yet you cannot find the information then go to YouTube (if on a tablet use the one on your default browser as it is easier to find) then search for the older videos.


Robo Duck 

Robo Duck was an ultra-heavy bot with an extremely high health along with an extremely slow speed and absolutely no protection. This bot could also sit on beacons. Its ability was a monstrous “QUACK”.  It was never released, due to that one overpowered ability and its incredibly high health that would have surely broken the game.

This poster was intended as a practical joke by Pixonic.



The Bastion was a heavy robot that possessed two heavy weapons. It was replaced by the Raijin before release.

The Bastion's name lives on in Raijin's 'Bastion Mode', indicating that the design of the Raijin originated with the Prototype 'Bastion' Robot. Bastion's ability was called 'Hold Position' before it was cancelled by Pixonic. It was one of the first robots to come the closest to being released, with Pixonic even releasing a video about it on its upcoming release.

Unfortunately, it was replaced by the Raijin before it ever came out. Nevertheless, it is well remembered by many, through Raijin's special ability and a particular Halloween update mainly featuring Bastion Ghost robots on all battlefields, which was a pleasant suprise for many players. Its more realistic design and appearance compared to current robots as well as its history make the Bastion one of the more popular cancelled robots.




The Robespierre would have been a robot with one light, two medium, and one heavy hardpoint. Many believed that it would have been a heavy version of the Golem because of the visual similarities.

If it was to possess similar if not more health than the Golem, then it was probably never released due to it having too much firepower compared to other robots at the time, especially if you consider that it would presumably have also had more health than the Golem.

Sentry (other name: Sentinel)

Unfortunately, there is little known information on what the Sentry looked like, just that it had 3 medium weapons and four legs. It appeared in the Roboduck poster along with Bastion, and presumably was planned at around the same time. However, no videos were ever released on it, and it was cancelled soon after.

The only source of information on its appearance is the Roboduck poster (see above) which gave its rough outline. The Sentry was probably replaced by the Fujin, possessing similar looks and firepower. Like the Bastion and Raijin , the Sentry 'lives on' through the Fujin's ability, called 'Sentry Mode'.

The Sentry may have been the hidden robot in Springfield, as it bears huge resemblance to the Fujin (like the hidden robot), however it did not have any known relations to the Japaneese faction, along with the hidden robot (the wording at the front of the robot is replaced with a serial number).

Unknown Japanese Faction Robot (possible Hellburner prototype)


Possible Japanese robot concept art

This robot may have been cancelled due to its 'rising sun' paint job and possible link to Imperial Japan. This paint job could have understandably caused concerns in the player-base of Japan and countries which had previously been conquered by it.



Eska - The Schutze 2.0 that never made it

The Eska is one of the most recent cancelled robots. It appeared on the test server equipped with three light weapon slots and used the hull of the Schutze

Its ability granted it stealth with no time limit, at the expense of being able to fire its weapons. As a light robot, it was relatively speedy as well. Eska's basic concept was integrated into the Loki, along with its hardpoint choices.


Possible Trident prototype


Developers working on the Trident

In the old WWR (Walking War Robots) website there was a “propose you own weapon competition” and the “revolver missile” won. It is unknown what happened to the model, but after some development the Trident came in.

It is possible that the model was scrapped or that the two events were mere coincidences.



A Zeus model was used to test the damage

A possible Ember or Redeemer prototype, with a range of 350 meters. No model of the weapon was ever released, with a Zeus model being used on the test server. 



One of three other hardpoint variations from the Pulse

The Pulse had different setups medium, light, and heavy (using a transparent Orkan model). Players could vote on which hardpoint should be released on the live server. It was extremely overpowered, creating a huge explosive dome when fired, which is probably why it was never released.

This weapon's animation was later used for Hellburner's Overload ability, as well as Mercury's Helldive ability.

Prototypes L1, L2 and L3


A model of the Trebuchet was used

The weapons L1, L2 and L3 were light weapons that used the model of the Trebuchet when they appeared on the Test Server. The official reason for the cancellation of these weapons is unknown. One arguable reason for its cancelling is that it had too much firepower and it could possibly be related to the Trebuchet. If so, the L3 prototype could have been an early version of the Arbalest. Not much else is known aside from various theories.

Bubble gun prototype


Prototype from “A Light Bot’s” thumbnail

Appearing in version 2.6.1., this weapon had no model for itself, so it used a transparent Magnum model. When fired, it shot an orb-like projectile that followed the target wherever it went. The orbs moved slowly but also dealt high damage on impact (possibly the reason for it being cancelled).

Heavy Homing Missile (possible Chimera or Thermite) Prototype


Three glowing models were used in the test server.

This weapon was first tested in the 2.5.0 test version. Like the bubble gun, it had no model, so it used a transparent spiral. 3 versions were made, with 1 firing like the spiral and 2 firing like the hydra. It was probably scrapped due the fact that it was supposed to be a mid-range missile and dealt too much damage.

It could be possible related to the Thermite , despite the longer range. This could have also been the same weapon that appeared on the test server about a year later as the Chimera.

Possible Tempest Prototype


It appears that it is an upside down gun attached to a robot

This appeared on the version 1.9.1 test server.

The design seems to be very closely based on more real-world firearms. It is very similar to the Tempest only with a much shorter reload time.

Possible Molot T prototype


Seen on an old Rogatka

YouTube video featuring the weapon:

You can see a Rogatka and a Griffin using it.

Kang Dae Prototype


Old Kang Dae prototype model

Was originally intended for the final game but was scrapped, and was replaced by a model with a sleeker design.

Game Modes and Other Features

Middle Beacon Energy Shield


Middle beacon energy shield

This feature placed an indestructible shield in every center beacon, although it would have probably been unbalanced as players on the same team could just shelter behind it and prevent anyone from capturing it due to the protection given by the energy shield.

Although teams could still win without capturing centre beacon, this game feature would have decreased the chances of the centre beacon switching and would have given a considerable advantage to the team that captured the centre beacon first.

Trivia and Other Information

  • Maximilien de Robespierre was a French lawyer and politician who was executed during the French Revolution by the Guillotine
  • Designations for guns used by the British Army all begin with the letter 'L', which might have been referenced with the cancelled L1, L2 and L3 prototypes.
  • The Eska was commonly referred to as the 'Schutze 2.0' by members of this wiki. This was due to the fact that it was essentially an upgraded Schutze in all but name, boasting superior firepower and an ability.
  • Pixonic often scraps designs which leave many robots and weapons which were never released. This leaves us to believe that there are several other cancelled prototypes that are unheard of so far.
  • Pixonic sometimes releases robots inspired by other cancelled prototypes, such as the release of the Raijin after the scrapping of the Bastion.
  • This page has the longest name of all the pages in the War Robots Wiki.
