The two captains draw breaths at the exact same moment, and their bellows fill the air. "OPEN FIRE!"
In order of turns:
Gozrak draws a bead on the lead Mandalorian as the man starts forward. He takes the shot at the mine,  hitting it. It explodes, sending another arching off across the floor to explode with a bang in front of him. The Mandalorian is thrown back as the others dodge out of his way. He slumps against the wall, his blaster dropped. There appears to be a large hole in his chest.
The Mandalorians start towards the crew's cover, a few detonating the explosives on the ground with blaster bolts as they move forward. A few bolts hammer into the upturned tables, but most are concentrated on the Jedi defenders. Alec dodges, but is caught by a bolt, [2 damage], as Dessh snaps his blade up, sending one of the barrage bolts smoking into the ceiling. The others miss entirely. [Dessh does this as a reaction, but takes -5 cumulative penalty to the check each time per turn.] He doesn't have time to attempt to redirect the shot, only reacting to them as he darts towards the boarders.
Dessh heads for the Mando captain, as the passengers take shots around him. Ino hits one of the mandos in the chest as she snaps off a shot. Another passenger, a Rodian, follows her shot with a bulls-eye to the neck, and the Mando's trigger depresses, a barrage of bolts slamming into the ceiling as he falls.
Gal watches, eyes narrowed, at the captain. He half-crouches next to the two guards, a large blaster pulled and aimed at the opposing captain. She waits for him to make a move, snapping a shot off past Dessh. It completely misses. It impacts above the bar where the others had been.
Dundaree blinks as the shot hits above his head, then makes a swift motion. The four rise up from their crouches as one. Dund makes no sound except to depress his trigger. Completely blindsided, only one Mando on the end even turns before the hail of bolts tears into their sides. Only the barkeeper misses, his bolts hitting the deck, as the others take down the two on the end.
Alec frowns as his opportunity is lost, then is distracted as a bolt hits his side. He comes to a halt, blade blazing, and chucks
it toward the offending Mando. It grazes him, bouncing off a wall as it continues it's arc back to Alec.
The Captain makes his shot as the crew return fire with the Mandalorians. The withering counterattack that the defenders made had seriously impacted the enemy, only three soldiers and their captain remained. Most of the shots patter around the deck, but the Captain's blasts right into his target. The opposing captain takes the brunt of the bolt on his armor, throwing up an arm and taking aim at Dessh as the Jedi closes with him.
Alec: 28/30 HP
Your lightsaber will return to your hand next turn.
Gal will be NPCed after all other orders are in. This battle is completely unbalanced, have fun with it.
