Pocket Artillery

The Pocket Artillery is one of the three secret unlockable weapons in Mercenaries: Playground of Destruction.

Overview
Rendered as a pistol, it fires grenades (at a much slower rate than Grenade MGs) and carries 100 per magazine, with only 50 in reserve strangely enough. It is dropped in the Secret Weapon drop, but is arguably the weakest in the set. Still, it is quite powerful, doing very similar amounts of damage to a typical grenade.

It can be acquired in the Cheat Weapons Drop, which can be unlocked in the Merchant of Menace by verifying all Deck of 52 members.

Trivia

 * Due to being the only 'pistol' in the game, the Pocket Artillery features multiple strange properties. It is held with both hands when equipped, shares the same reload animation with the RPG, and when holstered appears on the mercenary's back and glitches through their shoulder, similarly to the Street Sweeper.
 * It's likely that the original Pistol was intended as a weapon but ultimately cut from the game, possibly due to not having time to make animations for it.
