In The Lost and Damned, the first episode of Downloadable Content for Grand Theft Auto IV, six new weapons are introduced. While the existing weapons can be obtained from Terry's Gun Van, underground gun shops, and the various spawn points throughout Liberty City, the new weapons can only either be bought from Terry or spawned at either safehouse after completing a certain number of Gang Wars.
NOTE:This weapon is NOT obtainable during multiplayer.
- Cost: $700 per unit
- Carrying Capacity: 25 Units
A crude homemade device that creates a large explosion. A pipe bomb behaves exactly like a grenade, as it can be cooked to shorten its detonation timer. It is especially effective when thrown into the midst of a large number of enemies or rolled under a vehicle. This weapon is slightly more effective than grenades, but they release smoke when thrown, which can give away their position.
NOTE: If the player switches from one thrown weapon to another, the player loses all units of the previous weapon.
Automatic 9mm (CZ-75 Automatic)
- Cost: $500 + $15 for each additional magazine
- Caliber: 9x19mm Parabellum
- Magazine Size: 17 rounds
- Carrying Capacity: 1,200 rounds
With one pull of the trigger, this 17-round 9mm shoots constant rounds at a high rate of fire, making it ideal for a drive-by if the player lacks an SMG. It is deadly accurate, but not very powerful.
NOTE: If the player switches from any other handgun to the Auto-9, the player loses all extra rounds beyond 1,200.
- Cost: $600 + $5 for 2 shells
- Caliber: 12 Gauge, 00 Buckshot
- Magazine Size: 2 shells
- Carrying Capacity: 160 shells
This short-barreled shotgun features a deadly wide range, especially devastating at close range. It automatically reloads the two shells it fires. This weapon can be used from a motorcycle. Despite the absence of a pump-action mechanism on the Sawn-off Shotgun, the player still pumps the gun if blindfired while in cover. Sawn-off means it has very poor range and accuracy, but much more damage per pellet than other shotguns.
NOTE: If the player switches from the Sawn-off Shotgun to either the Pump Shotgun or Combat Shotgun, the player loses any extra shells beyond 80.
Assault Shotgun (DAO-12)
- Cost: $3,500 + $25 for 8 shells
- Caliber: 12 Gauge, 00 Buckshot
- Magazine Size: 8 shells
- Carrying Capacity: 250 shells
Also referred to as the "streetsweeper", the "striker" or the "jail breaker", this shotgun is fully automatic, firing rounds constantly, and tearing through anything caught in its crosshairs, whether it be flesh or machine. The Assault Shotgun is based on the Protecta variant of the Striker as it features a charging handle and an automatic cartridge ejection system. The magazine of the real-life Striker has a 12-round capacity, yet the in-game version is limited to 8.
NOTE: If the player switches from the Assault Shotgun to any other shotgun, the player loses any extra shells beyond the carrying capacity of the replacement weapon.
Grenade Launcher (Heckler and Koch HK69A1)
- Cost: $7,000 + $700 for each additional grenade
- Caliber: 40x46mm HE grenade
- Magazine Size: 1 grenade
- Carrying Capacity: 20 grenades
The grenade launcher fires 40 mm grenades with more accuracy, higher velocity and to greater distances than a person throwing a hand grenade. It only holds a single grenade and must be reloaded after each shot, but it is exceptionally effective. The player must arc their shots (aim higher than the target) when engaging targets at long-range to compensate for gravity. Grenades fired from the launcher detonate on a fuse and may be launched at and bounced off of walls and around corners to fire at tricky targets. Although the grenade launcher cannot be used effectively against aerial targets, the grenade launcher has a higher carrying capacity than the Rocket Launcher.
The grenade launcher is also available in The Ballad of Gay Tony; however, the weapon has been modified; the fuse has been shortened and if the player gets a direct hit on a vehicle or person, the grenade explodes on impact.
NOTE: If the player switches from one heavy weapon to another, the player loses all rounds for the previous weapon.
- While the Combat Shotgun from GTA IV is still present in The Lost and Damned, the gun is modified to be appear with a pistol grip and a different gun stock derived from the game's Carbine Rifle. Despite these differences, the Combat Shotgun sold at any gun shop or from Terry's gun van is depicted in its original GTA IV form.
