Weapons

BioShock
Jack is given a wide arsenal of weapons in BioShock, ranging from several types of firearms to genetic alterations. Ranged weapons can be upgraded at Power to the People stations.

Plasmids


Plasmids are genetic alterations that can be used as devastating offensive and defensive weapons. They are found, obtained, or bought with ADAM throughout the course of the game. They are special serums made from processed ADAM that introduce special stem cells to replace normal ones, allowing for genetic modification and real time mutation, granting special abilities. Plasmids are powerful, but excessive use of them helped to bring about the downfall of Rapture. Jack has a limited number of slots for actively equipped plasmids. The player can change his currently equipped plasmids at a Gene Bank. The player may purchase additional slots and select plasmids at a Gatherer's Garden. Their use requires a supply of EVE.

Research Camera


The Research Camera does no damage itself, but it is a deadly addition to the arsenal. It is equipped the same way as a weapon, and uses film to take pictures that unlock biological weaknesses and hidden secrets about every Splicer, security device, and Big Daddy. In each tree, there are five levels of research that require increasingly more photos to complete. On the first, third, and fifth levels of completed research, a permanent damage boost is applied against the researched enemy type. The second and fourth levels of completed research yield various Gene Tonics and other bonuses that are extremely useful. Little Sisters are the exception, as a permanent increase to health and EVE is given for each completed level of research.

Wrench


The Wrench is the first weapon and the only melee weapon Jack acquires in the game (unless the putter used in a single cut scene is counted). The design is based on a 2.5" pipe wrench and works very well with the Winter Blast Plasmid. It is the only weapon in the game that cannot be upgraded, but there are a number of Physical Tonics and Combat Tonics that enhance Jack's combat ability with the Wrench. When properly equipped with these tonics, the Wrench has the highest damage per second of any weapon in the game. Big Daddies can also be successfully defeated with it, but they are highly resistant to melee damage. Some Splicers also carry a wrench and will drop it when killed. These wrenches can then be picked up like any other weapon a Splicer drops. However, there is no apparent reason for doing this, as the Wrench has no ammunition. The Wrench is also an excellent weapon choice in order to conserve ammunition for other weapons.

Pistol


The Pistol is the first ranged weapon acquired in the game. It is based on the Webley Mk IV revolver, chambered in .38 S&W. It has a good rate of fire, good range and accuracy, and does a moderate amount of damage. Its main weaknesses are small clip size and low ammo reserve capacity. However, the damage and clip size can both be increased with upgrades at a Power to the People station, making the Pistol a far more effective weapon. Ammo for the Pistol is abundant for the first half of the game, making it a choice weapon for many scenarios.

Machine Gun


The Machine Gun is the second ranged weapon acquired in the game. It is based on the 1921 Thompson "Chicago Typewriter" submachine gun. It fires a rapid spray of bullets, each doing a moderate amount of damage. Its main weaknesses are heavy recoil and low accuracy at long range. However, the damage can be increased and the recoil reduced with upgrades at a Power to the People station, increasing the Machine Gun's effectiveness. The Machine Gun has high clip and ammo reserve capacities, and ammo is widely abundant throughout the game.

Shotgun


The Shotgun is the third ranged weapon acquired in the game. It is based on 1950 Remington 870 shotgun. It fires a wide burst of pellets with high damage that are most effective at a short range. Its main weaknesses are ineffectiveness at long range, a low chamber capacity, and a slow rate of fire. However, the damage and the rate of fire can be increased with upgrades at a Power to the People station, making the Shotgun even more powerful. The Shotgun has a high ammo reserve capacity, and ammo is common throughout the game.

Grenade Launcher


The Grenade Launcher is the fourth ranged weapon acquired in the game. It is a custom assembly of household and commercial parts. It fires grenades that do high damage and have an wide splash damage radius. They are fired at an arc, making targeting at long range require some estimation. Its main weaknesses are a low ammo cartridge capacity, a slow rate of fire, and the potential for collateral damage. However, the damage can be increased and immunity to collateral damage can be gained with upgrades at a Power to the People station, further increasing the usefulness of the Grenade Launcher. The Grenade Launcher has a low ammo reserve capacity, and ammo is somewhat rare throughout the game.

Chemical Thrower


The Chemical Thrower is the fifth ranged weapon acquired in the game. It is a custom assembly of household and commercial parts. It fires a straight, continuous stream of chemical substance as ammo is consumed. Its main weaknesses are a slow reload time, ineffectiveness at long range, and a very high rate of ammo consumption. However, the effective range can be increased and ammo consumption rate decreased with upgrades at a Power to the People station, making the Chemical Thrower a highly efficient weapon. The Chemical Thrower has high ammo cartridge and reserve capacities, but ammo is somewhat rare throughout the game.

Crossbow


The Crossbow is the final ranged weapon acquired in the game. It is based on the Morris Model M Crossbow. It fires single bolts with high damage that are effective at any range. Bolts that are fired sometimes do not break on impact, allowing them to be recovered and reused. Its main weaknesses are a slow rate of fire and reload time. The damage can be increased and the chance that a bolt will break can be reduced with upgrades at a Power to the People station, making the Crossbow an efficient weapon with nearly limitless ammo. The Crossbow has a high ammo reserve capacity, but ammo is rare throughout the game.

BioShock 2
Subject Delta has a powerful arsenal in BioShock 2, from unstoppable melee attacks to devastating ranged weapons. Plasmids are wielded with weapons simultaneously.

Plasmids


Unlike his later successors, Delta is open to genetic alteration, allowing him the use of plasmids. He has a limited number of slots for actively equipped plasmids, and can swap them out at a Gene Bank. Upgrading a plasmid to the next level also unlocks an alternate method of use for that particular plasmid. A larger suite will be available, as well as upgrade levels for each.

Drill
The Drill is a powerful offensive weapon, doing extensive physical damage. It can be used to charge an opponent with a single attack, or drain its health by direct boring. Merely revving the weapon will often times cause Splicers to retreat. The Drill can be upgraded, either by adding a lubricating nozzle to reduce the weapon's fuel consumption rate or by fixing a diamond tip to deal extra damage to armored enemies.

Hack Tool
The Hack Tool is a gun that allows the hacking of security devices and other machines at a distance. It shoots Remote Hack Darts which initiate an on-screen hacking display on impact. So far only one ammo type, the aforementioned hack dart, has been discovered so far.

Rivet Gun


The Rivet Gun is a single-shot, semiautomatic ranged weapon that fires high-speed rivets. It is fast, accurate, powerful, and has low recoil. It has base ammo, advanced ammo, and inventable ammo variants. It can be upgraded as the game progresses.

Gatling Gun


The Gatling Gun is a rapid-fire, automatic ranged weapon that fires high-speed rounds. It has a very high rate of fire and high-capacity magazines, and is capable of inflicting tremendous and continuous punishment before having to be reloaded. It has base ammo, advanced ammo, and inventable ammo variants. It can be upgraded as the game progresses.

Double Shotgun


The Double Shotgun is a double-shot, close-range weapon that fires wide blasts of pellets. It is a slow-firing, but devastating weapon up close on single or multiple targets. It has base ammo, advanced ammo, and inventable ammo variants. It can be upgraded as the game progresses.

Spear Gun


The Spear Gun is a single-shot, ranged weapon that fires high-powered spears. It is a slow-firing, but powerful and accurate weapon from any range. It has base ammo, advanced ammo, and inventable ammo variants. It can be upgraded as the game progresses.

Plasmids
Upgrading a plasmid to the next level also unlocks an alternate method of use for that particular plasmid. A larger suite will be available, as well as upgrade levels for each. Aero Dash, Geyser Trap and the Houdini Plasmid are exclusive to multiplayer. Plasmids and weapons are wielded simultaneously.

Weapons
Players will have a unique melee weapon depending on the character they're playing (this is purely a cosmetic change, though). All of the weapons from the original BioShock, save for the Wrench, will be returning for the multiplayer experience. Here is the list:
 * Research Camera
 * Pistol
 * Machine Gun
 * Shotgun
 * Grenade Launcher
 * Crossbow
 * Chemical Thrower
 * Rivet Gun
