The Drone Gun CS-Virus is a rare weapon that shoots three small drones, which jump at and attack enemies, draining their health. The weapon has a slow rate of fire, though the drone projectiles can be quite effective at quickly removing a character's health. This weapon is manufactured by the Civil Security.

It features an open barrel, with a hump on the back of the weapon. This weapon is not reliable on difficulties above easy, as the enemies will switch to PSI Blades and destroy the drones before they can reach them. Strangely, robots are also affected by the virus. It can be used against the Corvettes on level 41 to destroy them quickly.

The Drone Gun CS-Virus was most likely made to take down technology such as Corvettes or other vehicles; they go into the cockpit and kill the enemy manning it. The vehicle is not harmed, however, with the exception of Drones and Corvettes.

The Drone Gun is found only on Level 40, being used by Civil Security Bosses. The weapons can be taken from crates and picked up by the Marine and his allies, though the main protagonist will have to drop his Ray Gun C-01y. It cannot be upgraded or purchased in the equipment shop.


Drones are small bug-like capsules that can be fired from the Drone Gun CS-Virus. These are destructive modules, as they will drain the health of any enemy they come into contact with, and they will follow them. Drones do not behave like bullets, they are affected by gravity, and they will jump to various locations in order to attack enemy players. After a short period of time, drones explode and die. Once attached, it will stick on.

If one can lead the drones into water where they become very sluggish, as they cannot swim as well as player can. Players can also cut them with your PSI swords, or get to high grounds where the drones cannot leap.

Acquiring a Level 3 Drone Gun

Normally, in the campaign, players can only obtain an unupgraded Drone Gun. However, with the use of cheats, it's possible to obtain a level 3 drone gun. The steps are quite similar to obtaining a Grenade Launcher CS-SpamThemBaby.

First, obviously, you must beat the campaign on any difficulty to unlock Root compatibility.

Secondly, with root compatibility enabled, go to Level 40 on any difficulty. Turn on the God cheat by typing "god" or "god 1". Have it enabled for the Marine and Proxy. (Noir Lime doesn't need to survive, unless you trigger him to appear BEFORE you do the next step)

Type "dm" to enable Deathmatch mode. Switch to Proxy, as the glitch doesn't work with the Marine.

Go to the area with the Civil Security Bosses who have the Drone Guns. At this point, they're all fighting each other. Once you kill a boss who has a Drone Gun, you'll see that you can pick it up, despite it being upgraded. Ditch your current 9 slot weapon if you have one, and go pick it up as Proxy. Then, finish the level. Congratulations, you now have a level 3 Drone Gun!

If you want to give it to the Marine, simply start up a Marine/Proxy co-op level and trade slot 9s. (Have Proxy drop the weapon and have the Marine pick it up)

Level 3 Drones are incredibly powerful, killing even the strongest enemies in seconds (outside of higher difficulties where they cut the drones off). It's also great for level 41, as the drones will kill the Drone Controllers piloting the Corvettes near instantly.



A drone.

  • The drones can be destroyed by cutting them with PSI Blades if they are encountered in close range combat.
  • This weapon is also infamous in Multiplayer, especially when swords are disabled. 
  • A maxed-out Drone Gun CS-Virus has the highest damage per second of any weapon in the game.
    • A SINGLE maxed drone has the DPS of swords, in addition to the range and homing. 
  • You can use the Kinetic Module to lift the drones.
  • This gun is only found in Level 40.
  • It is unknown why the drones can kill Androids. It's possible the drones physically bite through their bodies, damaging them.
  • This weapon not only serves to kill drones or other vehicles. If you're playing with normal difficulty and there are numerous enemies waiting for you, launching the virus may be the only option for survival as the virus may cause a fight between the enemy teams. On easy mode of difficulty the enemies don't cut drones.
  • Maps that contain this gun will not be approved.
    • Most likely, the main reason is glitchy scoring: if Player A kill Player B with this gun, Player A will get no score from the kill and Player B will be stated as "Player B died" in the chat.
  • This weapon is useless on Normal/Hard/Impossible difficulty because the drones will just be cut by the enemy using their PSI Blades. However, they can still damage and distract enemies, though.
  • This weapon has the lowest rate of fire.
  • It is unknown why it only is seen in level 40, it may have been a newly made weapon, or just given to high ranked Civil Security Bosses.
  • The weapon itself is shaped like its bug projectiles.
  • This is the only homing weapon in the game.
