Damage Increase: Unlocked at Rank 37. Increases the Nail Gun's damage output, but decreases its accuracy.
The Nail Gun's rev-up time can be nullified by tapping the fire button. Although very noisy, it'll allow the player to attack any enemies instantly.
Being stunned in any way will reset the Nail Gun's rev-up timer to zero.
The Nail Gun is the best Anti- Big Daddy weapon, capable of killing one at full health in two clips.
The Nail Gun's large clip size makes it effective against groups, allowing the player to kill five players in a single clip (assuming every shot lands on target).
The Nail Gun is best suited for mid- to close-range combat, as its low accuracy makes it unrecommended for any other form of combat.
Although this weapon is easy to use during combat, its rev-up time takes some time to master. If the player has spotted an enemy, take cover, rev up and attack.
The Nail Gun's Extended Magazine upgrade presents no disadvantages, and will increase the weapon's effectiveness against groups and Big Daddies.
The Nail Gun's Damage Increase upgrade makes it supremely effective in close combat, although the weapon will become ineffective even at medium ranges.
The Nail Gun's Burst Fire upgrade will decrease its effectiveness at close ranges, but will make it much more accurate over long distances.
The Grenade Launcher's ease of use makes it a suitable counterpart to the Nail Gun, able to deal large bursts of damage versus entire groups at a time.
The Crossbow can provide long-range support in case the target is too far.
The Tommy Gun works similarly to the Nail Gun, and can potentially save the user's life if caught unaware.
Winter Blast will prevent enemies from escaping and, if the player has the Extended Clip upgrade and is fighting a Big Daddy, can allow the player to kill the latter without ever having to reload.
Geyser Trap can be used to throw enemies into the air, allowing the player to rev up while doing so.
Houdini will allow the player to reappear at a target's blind spot and ambush them.
Insect Swarm will disorient enemies, giving the player time to rev up safely.
Big Game Hunter will increase the Nail Gun's effectiveness against Big Daddies even further. If the player has the Extended Clip upgrade, one will even be able to kill a Big Daddy in one clip.
Speedy Recovery will allow the player to quickly regenerate health, which is almost always necessary after a fight when using this weapon.
