Overview

Star Wars: Knights of the Old Republic II - The Sith Lords is a third-person science-fiction role-playing game developed by Obsidian and published by LucasArts for the Xbox on December 6, 2004 and the PC on February 8, 2005.
Set around five years after the end of the Jedi Civil War, The Sith Lords follows the adventures of a former Jedi Knight (a customizable protagonist known as the Exile), as they must restore their connection to the Force while finding the remnants of the near-extinct Jedi Order and escaping the clutches of a mysterious Sith force.
It is the first game developed by Obsidian (founded by ex-Black Isle employees) and is built on the engine used for the original Knights of the Old Republic. The game features numerous gameplay changes, including a more streamlined user interface, a crafting system, and enhanced character building (most notably allowing players to build or lose influence with their companions, affecting their alignment and unlocking new abilities and dialogue).
The game is known for its rushed development cycle, leaving some of the game in an "unfinished" state with various unused content in the game files. This led to some unofficial add-ons in the PC version to restore this content, the most prominent being The Sith Lords Restored Content Mod.
It was later digitally re-released for the PC via Steam (on August 23, 2012) and via GOG.com (on January 2015). On July 21, 2015, the Steam version received an enhanced Steamworks update by Aspyr (adding Mac and Linux support, Steam Workshop support for mods, Steam Cloud support for savegames, Steam Achievements, dedicated controller input support, and widescreen support).
Squad Roster
The game includes numerous companions that can join the Exile in their missions. Players can choose up to two squadmates at a time and can switch members at certain areas when out of combat. Unlike the previous installment, some characters are mutually exclusive based on the Exile's gender and alignment. The fates of certain characters can change over the course of the story.
At certain points of the game, players will have to progress with a group that does not include the Exile. For example, the optional tutorial mission has players in the role of T3-M4 (who temporarily recruits fellow utility droid 3C-FD).
Unlike the previous game, all companions have at least one exclusive feat or ability that gives them specific advantages over other companions (for example, droid G0-T0 can float over mines without tripping them). As the game progresses, the Exile can gain and lose "influence" with each character, affecting their alignment (for both dialogue and Force Powers) while giving them new bonuses (and, for Force-sensitive characters, multi-classing).
Story

5 years after the story of the original KOTOR, the story of KOTOR II follows the adventures of the Jedi Exile (canonically a female, and will henceforth be referred to as such), a Jedi who was punished for her part in the Mandalorian Wars with excommunication from the Jedi Order. After escaping from a ruthless assassin droid on the mining station of Peragus with her companions Kreia, Atton Rand and T3-M4, the Exile sets about finding a way to stop the hidden Sith menace and recovering her connection to the force--which was seemingly cut off by the Jedi Council after her excommunication.
Mentored by the uncompromisingly pragmatic Kreia, the Exile gathers more and more companions (including a Sith Lord's former apprentice and the leader of the tattered remains of the Mandalorians) and travels to a wide variety of planets in her search for the last remaining Jedi Masters. As she travels about the galaxy, the Exile gains insights into the nature of the force, the flaws inherent in its black-and-white morality, and the dark pasts of her companions. Depending on her interactions, the Exile may begin a romance with either Atton Rand or the Disciple (if male, then the Exile can romance the Handmaiden or Visas Marr).
After gathering the remaining Jedi Masters at the ruined Jedi Enclave on Dantooine, it is revealed that it was not the Council that cut off the Exile from the force at all. In fact, she severed her connection as a defence mechanism following the destruction of Malachor V--the sheer scale of which should have killed most force sensitives outright. The Council also reveal that the Exile has not recovered her connection to the force at all, but is rather acting as a leech, draining the force from those around her. Given her status as a "wound in the force", the Council resolve to actually sever the Exile's connection to the force, and nearly succeed but for the intervention of Kreia. Kreia berates the Council for their ignorance, and severs their connection to the force, killing them instantly. It is here that Kreia is revealed to be the Sith Lord Darth Traya, Lord of Betrayal. Following her recovery from the ordeal, the Exile tracks down Darth Traya to the ruins of Malachor V, where they confront one another, student and master, for the final time.
On a dark-sided playthrough, the Jedi Council scene is decidedly less crowded--as the Exile has already killed most or all of the Jedi Council. If this is the case, Kreia instead berates the player for her brutality and foolishness, branding her a failure. The confrontation on Malachor V still occurs, but rather than it being the end result of the Exile's quest for insight and harmony, it is the end result of the Exile's lust for power.
Cameos
Two popular characters from the original game make cameos in KOTOR 2. Carth Onasi will appear and inquire to the Exile if she knows of Revan's current whereabouts. When it turns out the Exile does not know what happened to Revan, a short scene of a conversation between Carth and Bastila Shan plays, discussing why Revan left, and where he/she might be. If the player played the original KOTOR as a dark side character, Bastila will appear in a Sith Holocron on Korriban. Also on Korriban, there is a cave that the Exile must be an extremely high level to enter. Upon entering this cave, the Exile is shown Force apparitions of Revan and Malak, in addition to another appearance by Bastilla. Revan wears his/her mask however, so the player does not see his/her face. In addition to these, HK-47 and T3-M4 both return as party members in this edition. Also returning is Canderous Ordo, but he goes only by the name Mandalore, and never removes his helmet. It is only towards the end of the game that the player discovers that Mandalore is in fact Canderous. No other party members from the original KOTOR appear in KOTOR II.
Locations

KOTOR II Included a comparable amount of planets to the original KOTOR, all of them fully explorable:
- Peragus II - A mining facility on an asteroid, the game begins in this mostly abandoned area, with the Exile having to gain access to the Hangar bay and escape.
- Telos IV - A planet ravaged by Sith orbital bombardment during the Jedi Civil War, it is now the subject of a massive restoration effort, with the surface being terraformed back to a habitable environment, and the massive Citadel Station orbiting overheard.
- Dantooine - A returning planet from the original KOTOR, Dantooine is in the middle of a rebuilding effort, after the Sith attack on the Jedi enclave near the end of the original KOTOR. A group of mercenaries wishes to overthrow the fledgling government on this planet, and they launch a full assault while the Exile is on-planet.
- Korriban - Another returning planet from the original KOTOR, Korriban, the former seat of Sith power, has fallen into ruin. After Revan left known space, the remaining Sith turned against each other, and their empire collapsed. Nothing remains now but ruins and tombs.
- Onderon - A planet in the throes of a civil war between it's monarchy and it's military. Onderon is also considering seceding form the Republic.
- Dxun - A moon orbiting Onderon, Dxun is covered in jungles and ruins, including the tomb of ancient Sith Freedon Nadd. A secret Mandalorian conclave calls this moon home, led by Canderous Ordo, who has assumed the title of Mandalore.
- Nar Shaada - A seedy industrial world, stuffed with refugees from the Jedi Civil War, and crawling with crime bosses and bounty hunters.
- Malachor V - The planet where the final battles of the Mandalorian war took place. The hulks of ships destroyed in the final battle between Republic and Mandalorian forces clutter the planet's orbit.
