Help your fellow super

You decide to lend a hand. These laser guns are dangerous, but they still point in a straight line. You circle around the gunfight and approach the thugs from behind. One by one you knock the stragglers out. Even though some of them had noticed you, they are too disorganized to properly communicate with the rest. Eventually you manage to take out one of the guys with the laser gun, and grab it for yourself.

The weapon looked alien in design. Nothing made sense. Even the grip didn't look like humans were meant to use it. Whatever. You point it at the thugs and mimic their actions. Nothing happens.

"Shit." You duck down to dodge a beam, and then roll away from a burst of gunfire. They were starting to focus their fire on you, and that was very bad news.

"Come on, how do you w-" punching random parts of the weapon, you accidentally trigger it. A lance of energy shoots up into the sky, nearly blowing a hole in your head. You raise it at the thugs again, this time successfully firing the weapon. It impales a man in his chest, instantly killing him.

While you were sowing chaos, the lightning-user was still shaving down the numbers of the thugs. Once they were down to single-digits, the thugs lost their morale and started fleeing. You manage to gun down most of them, but you can't be sure you got them all.
