RPG

"Hefty but portable, the BARNSTORMER shoots missiles that explode into deadly shrapnel."

The Barnstormer, known in-game as the RPG, is one of the weapons in Booker DeWitt's arsenal in BioShock Infinite. Although it can only fire a total of two shots before having to reload, each one delivers an explosive payload capable of taking out large groups as well as fortified constructs. In between shots, Booker must crank the weapon to chamber the next rocket. Booker can also use it to aim, although its range is limited to its crosshairs.

The Barnstormer RPG is an incredibly powerful weapon that fires slow-moving but deadly rocket-propelled grenade toward your enemies. These rockets inflict incredible damage and can take out several enemies in a single shot or destroy a Heavy Hitter very quickly.

It's best to employ the RPG against adversaries that are fairly far away, as using it too close can backfire, since Booker isn't immune to the explosion damage caused by RPG ammo. It's also generally not worth the ammo to use the RPG against single foes—save the RPG for heavy hitters or massive groups.

RPG explosions have the same fire effect as the Devil's Kiss Vigor, which allows the player to use it instead of the Vigor. Also, RPG rockets can set oil slicks ablaze, creating a devastating wall of flames! Firemen are unaffected by the blast, though.

Be careful when using the RPG against distant enemies because its rockets will not travel as quickly; opponents may have time to move out of the way long before the rocket reaches them.

This weapon should NOT be used against the Boys of Silence in Comstock House. Despite its firepower, the boys' tear-manipulation will protect them from the blast, and player will only waste more ammo if they use the RPG on the summoned minions.

Trivia

 * In reality, rocket launchers were not invented until World War II. However, it may be possible that the RPG, alongside the Machine Gun, was one of the technologies Columbia obtained from Tears.
 * If one looks closely, the RPG has no exhaust port. This would cause Booker to fall over or at least stumble back when firing. Beasts probably also use their armor to weigh themselves down so they don't get knocked back when they fire.
