A self-eating snake will destroy your opponents and steal their souls for you. Great AoE and fire-fire-fire!

—Weapon description in the Gallery

The Ouroboros is a Backup weapon introduced in the 16.5.0 update. It can be obtained for a limited time as part of the Trader's Van event in the armory.


It appears as a curved black/orange dragon with orange spines, a black grip, a blue lever, a dark grey tail, and a black head with a fiery projectile in its mouth.

When reloading, the weapon will create a defensive radius on the ground around the user, damaging any enemy that is within the radius.


It has good damage with strong burning, a decent fire rate, a medium small capacity, and a slow mobility.

  • Target weakened opponents or/and aim on the head to conserve ammunition and less intense duel.
  • Use it in close-medium ranges.
  • When used with precision and skill, it can kill about any opponents, including the well-armored ones.
  • Take advantage of the weapon's Burning attribute on players, since the enemy will be damaged overtime if shot.
  • One can use the fiery radius when reloading as a means of defense.
    • In addition, it can also be used to counter charging melee users.
  • Jump while reloading since the damage radius is created around the feet of the user.
  • Reload frequently, so as to deal damage on those within your personal space.
  • Three Cat Spam with this weapon is useless as it has delay. But you can still use this weapon alone as it can kill quite quickly.


  • Pick off the user at long range.
  • Area damage and shotguns (in close range) make quick work of users.
  • Strafe while jumping to minimize the damage from the weapon.
  • Like most Backup weapons, being at farther ranges is effective for minimizing the chances of being hit.
  • Flank around the user then use a melee weapon to deal quick damage and then pull back.
  • Avoid getting too close to the user when they are reloading, since the defense radius could potentially kill.
