I just thought of a shotgun weapon design, similarly the wristgun, this would be connected at the elbow and have three barrels, that appear as though they were each welded together from three separate single-barreled shotguns. The trigger would be placed on what appears to be a secondary gun grip that the barrels are mounted on, the ammo chamber is one chamber separated by rails and it opens with a covering that reaches all three chambers. And as for upgrades: there could be upgrades that act like the third from Bioshock 2, the three basic elements: Fire, Electricity, and Ice. Also an upgrade that enables firing more than one barrel at a time, albeit slower. Ammo: Basic: 0000 Buckshot: like the normal rounds for a shotgun in the Bioshock Universe. Rare: Solid Round: A solid slug, deals high damage at cost of slow reload. Heavy Buck: very high damage and knockback at the cost of very slow reload, the rounds are heavy. Rubber Shot: deal small damage, but will ricochet up to two times, including enemies. Inventible: Cluster Rounds: deal small damage upon impact and moderate explosive damage after it explodes, does not catch target on fire. Venom Rounds: will deal small damage on contact and moderate damage over the next five seconds, and the damage stacks with multiple hits. Buck Rods: will go through up to two small enemies or one large enemy, does not go through armored enemies. Deals moderate damage to small damage.
