Boarding Party Breachers
Attached to the basic boarding party, the Breacher is a specialist in creating novel entry points though hardened positions. Equipped with a 12 gauge coil shotgun that fires flechette in a discarding sabot (though it should be able to fire any 12 gauge gauss shot), the Breacher can easily put down anyone they see, even through light armor, but the real meat of their capabilities lies in the breaching charges they carry. Each one is a shaped charge capable of punching a good-sized hole through a bulkhead, large enough for a boarding party attack through two by two. To make the most of this, the boarding party has been given proper assault training to clear a room while the enemy is still reeling from the shock. Furthermore, an extra goon has been added to the standard boarding party, who acts as the Breacher's "battle buddy".
Less materially importantly, the entire boarding party receives a paint pot to customize their helmet and the jolly roger on each shoulder.
"Memento Mori" Compact Railrifle
The Mori is a bullpup railrifle that fires 5mm slugs at nearing on hypervelocity. The mori is fed from quad-stacked mags that fit 60 rounds in a fairly short but chunky mag. The trigger actuates a piston in the chamber that shoves a round between the rails as well as actuating the capacitor, and this is where things get interesting, see, the slugs are coated in a material that readily bursts into plasma when exposed to relatively low (which is still really quite high) current, now this is obviously "cold" plasma in relatively low quantities, so it's not going to have any effect on target, but it acts as a buffer between the slug and the rails, greatly lowering rail deformation so we can use the damn things for more than 5 rounds (the pirate who tested the gun also assured us the bright blue sheath on the slug looks "fuckin rad.") The railrifle also notable has an integrated, compact 12 gauge gauss shotgun, and while there is talk of creating "micronades" for it, right now it only fires solid slugs, though any 12 gauge gauss rounds we make should work.
