The Revolver returns in Bioshock 4.
The Revolver is virtually the same as it was in Bioshock, except that it does slightly more damage than before. It has the same rate of fire, though a slightly longer reload time. When the protagonist melees with it, he either slaps whoever he was trying to melee, or he jabs them with the barrel, both doing the same amount of damage.
- Damage Increase - This upgrade increases the damage of the Revolver, as well as making the barrel look longer.
- Clip Upgrade - This upgrade doubles the clip of the Revolver, making it fire 12 shots instead of 6, and also makes the revolving mechanism bigger.
- Reload Time - Decreases time it takes to reload the Revolver, as well as making the pistol grip larger.
