Weapon LoadoutsEdit

Main article: Category:Viper Build

See the user build section for builds using this weapon.


  • Some have experienced bugs with this weapon's reloading. Try and stop pressing the sprint button while you reload. For some reason if you reload and sprint at the same time you might have some problems with fast reloading weapons. NOTE: This reloading glitch can be caused by game lag and low framerates, and can become so troublesome you can stand in place and it will constantly do the reload animation indefinitely or until lag improves. It is not recommended to use this weapon if you have problems with lag or framerate issues as this may become near usless in combat.
  • Although it is not recommended for long range fighting, correctly aiming and tapping the trigger will expel 1-2 bullets at once, and you may get a decent critical or headshot rate by doing this.


  • The Viper was released on the 18th of March, 2013 with Update 7.
