Flashpoint

Flashpoints are heavily scripted instanced areas where a group of up to four players will have to fight their way through waves of enemies in order to accomplish an objective and gain superior equipment and unlock achievements.

Official description
Band together with your most trusted allies to undertake some of the most dangerous missions in the galaxy! Flashpoints are action-packed, story-driven adventures that test a group of players to their limits, putting them up against difficult foes in volatile situations. You and your group need your wits, your skills, and all your resources to emerge victorious. Every Flashpoint begins with an exciting story and contains difficult decisions – choose carefully, because your group's choices have a meaningful impact on the challenges you’ll face, the enemies you’ll fight, and the outcome of the story! All the danger is certainly worthwhile; the rewards from Flashpoints are some of the most powerful you'll find.

Dialogue
Players will enter in several dialogue sessions with NPCs that may have a relevant impact on the flow of the story and of the Flashpoint itself. In order to make a decision rather than another during said dialogues, every player will have to select their preferred option, and then a random dice roll will decide which of the chosen paths the group will undertake. Regardless if one player's choice gets picked or not, his decisions will only affect his personal light side points or dark side points, and will not affect nor be affected by the choices of the other players.

Missions
A mission board that gives daily and weekly missions can be found in the Republic and Imperial Fleets.

Story
Story Flashpoints can be entered alone or in a group - they exist to see the story, and give you a special droid that will help you during fights.
