Striking with massive twin blades, the Redeemer fires the killing blow with its built-in shotgun.
The Redeemer is a hybrid gunblade that merges the functions of a shotgun with a melee weapon. Apart from its normal melee abilities, the Redeemer can also fire off a charged shotgun blast to hit enemies at range.
Unlike the Glaive or other throwing weapons, the Redeemer's ranged attack does not leave the user unable to use the weapon for several seconds, as the Redeemer never leaves the user's hands. Rapidly switching between ranged and melee attacks is thus possible with the Redeemer.
The Redeemer's shotgun blast shoots 10 pellets, each dealing the listed 75 thrown damage, giving the charged shot a total combined base damage of 750.
The Redeemer can be fired while sprinting unlike Primary and Secondary weapons. Charging the weapon to do so will momentarily slow the Warframe down at the start of the charge before resuming full sprint.
Ironically, the shotgun blast is silent, making it effective for stealth gameplay.
Unlike guns, the shotgun blast will not make a Volatile Runner explode on death.
The Redeemer does not have an ammo limitation, so the shotgun can be fired as much as desired.
Firing the shotgun does not invalidate the "The Sword Alone" achievement.
The charge attack function is affected by attack speed mods and Warframe abilities.
The maximum range of the charged attack is affected by Reach.
Channeling the shotgun shot will consume energy for each enemy hit per pellet, ex. If shooting 1 enemy and 3 pellets hit, it will take away 3*(energy cost) so a standard channeling efficiency weapon will take away 15 energy if 3 shots hit.
While the Redeemer has a very low listed Status and Critical Chance, the shotgun blast calculates the chances for both individually for each pellet, thus making the weapon's actual Status and Critical Chance with its ranged charged attack much higher than listed.
Each pellet benefits from the bonus damage of Energy Channel, meaning a shotgun blast after using a Warframe's fourth skill could do an additional 2000 damage before any other bonuses.
The Redeemer is the first weapon that requires two different weapons - the Vasto and the Dual Skana - as crafting materials.
The in-game description does not match the crafting requirements. It says it has an in-built shotgun, but the gun used to build it is a Vasto, which is a revolver.
The concept of a sword integrated with a gun is based off the real life concept of the Pistol Sword, although the Redeemer uses a sawed-off shotgun instead of a pistol.
In particular, the Redeemer's grip stance with the blade parallel to the user's arm is reminiscent of the concept of the Indian Pistol Katar.
Charging the blast with quick-melee and then jumping to cancel it will result in the Redeemer being held in combination with your current weapon.
