Star Wars: The Old Republic is getting an expansion called Onslaught soon and it will apparently allow players to stay loyal to their faction or sabotage it, on top of adding two new planets a new operation and several new abilities.
Gamers probably wince at the mention of BioWare and online multiplayer in the same sentence these days on the account of them being the developers of Anthem but the studio was responsible for Neverwinter Nights and Star Wars: The Old Republic as well.
Granted, the former was released 17 years ago as a major success and the latter eight years ago, successfully but nothing groundbreaking. Star Wars: The Old Republic still seems to have fared much better than Anthem since it's about to receive an expansion almost a decade into its lifespan.
Onslaught will bring about two new planets - Onderon and Corellia. The first planet has been the Galactic Republic's ally for a long time but it has a new king that could potentially renounce that allegiance.
Corellia is not entirely a new planet but the new Flashpoint will be located there as the Sith Empire prepares for a massive attack, hence the expansion name, and players can either help the new emperor wannabe or ruin his plans.
As you might expect, this will be the expansion's finale so you will need to go through the content on Onderon and one of its moons, Dxun, ahead of the main battle.
The official announcement on SWTOR's website makes it sound like the Empire forces will be superior but the Dark Council is aware of this and are already plotting against each other in anticipation of the spoils, which could hint at their weakness that could allow the Alliance Commander to tip the scales either way.
Onslaught will also add a new gear slot for the Tactical items. They will directly alter the way a player's abilities perform and will presumably add more variation to the game's combat in hopes of keeping it fresh. You can read the entire announcement and more details on the official Star Wars: The Old Republic website.
