The Big Damn Fight

Sergeant Chult, generally speaking, didn’t care about what anyone else had to say. This made him uniquely qualified to wield the Gigablaster 1. Whereas most modern weaponry had long since been made reliant on the relative quiet of lasers to shoot the things that need shooting, the Gigablaster 1 marked an experimental step in the opposite direction - what if we had a gun that managed to contain really big explosions in its chamber? They never made a Gigablaster 2.

Two alien infantry stood watch in front of the neatly printed sign denoting 'Civilian Power Control.' Though even untrained humans had proven to be able to take down these lowest-tier invaders, the only real duty that the pair had was to provide warning for the larger group inside should anyone defending the station arrive. They performed their duty admirably, since the two shots from Chult's hand-cannon each sent out an ear-rending roar of the high explosive shells being fired. The squad of aliens within started spilling out of the entrance, leaving the pair of infiltrators within to finish their investigation.

“You can't shoot with your hands over your ears, you coward!”
“Sorry, sir!”
“Less shouting, more shooting, Private!”
“C-can't we fall back to better cover, sir?”
“Potted plants are impeccable cover!”

“Oh good,” Tamatoa sighed. “We found them.”
“That is good! I had expected long hours of travel.” Also Willhelm beamed at her and loaded his sling.
“Why would you - nevermind, let's just go.” She unslung her own rifle in turn, and crouch-ran in a zig-zag down the hall.
“That is an unusual way to charge.” Also Wilhelm frowned, then ran directly down the corridor while twirling his swing at his side. “Battle is joined!”

A trio of stones whizzed out towards the aliens. One of the shots struck a soldier in its head between the many metallic protrusions jutting out of it, sending out a burst of purple blood before it dropped backwards. The remaining soldiers began to train their weaponized hands on the charging man, who had since let go of his sling. The gold weapon hung loose from its strap on his wrist, as an ancient metal axe had replaced it. His left hand held his cape out in front of him, and the beams fired from the formation of aliens deflected off of its glittering scales.
"No sorcery shall burn a gift of the Carp!" The invaders were allowed only a few attempts to shoot around his cloak-turned-shield before he was inside of their formation. When he pulled his left arm out from behind the cape, he revealed his sword already in hand and began laying about with both weapons amidst the mass of enemies.
