I own a railgun for sub defense, since that's what Aunt Doris intended. Four mudraptors break into my sub. "What the devil?" As i grab my methamphetamine and rifle. Blow a golf ball sized hole through the first mudraptor, it's dead on the spot. Draw my handcannon on the second mudraptor, miss it entirely because it's smoothebore, and nails the neighbours clown. i have to resort to the railgun mounted at the top of the ladder loaded with canister shot, "tally ho lads" the canister shot shreds two mudraptors in the blast, the sound and extra shrapnel set off flood alarms. Grab boarding axe and charge the last terrified rapscallion. It bleeds out in the ballast since boarding axe wounds are impossible to stitch up. Just as Aunt Doris intended.
