This past weekend, BioWare announced in a blog post that its massively multiplayer online role-playing game Star Wars: The Old Republic would receive its first expansion in nearly three years.

The expansion allows players to explore two new planets, a new Flashpoint on the war-torn world of Corellia, a new Operation set in the lush jungles of Dxun, an increased level cap, and more as it takes players back to the centre of the reignited war between the Galactic Republic and the Sith Empire. It officially launches in September and it’s free to all subscribers. Check out a gallery of the new expansion below!

The first of the new planets, Onderon, is filled with untamed jungles and savage beasts. The people remain loyal to the Republic but a new king could put an end to that.

Then, there’s Mek-Sha, which Bioware describes as an independent fueling station and boomtown controlled by the Hutts:

“This lawless den of smugglers, pirates, mercenaries, traders, and refugees has become a crossroads for the entire galaxy – a place where opportunity and danger can be found in equal measure.”

Over on Han Solo’s homeworld of Corellia, this new Flashpoint will bring players to a new area for both solo and group players. Dxun, Onderon’s largest moon, is teeming with wild jungle-life – drawing the attention of the unscrupulous Czerka Corporation as well as a band of fanatical Trandoshan hunters. The Operation will be available at launch.

The company also announced that players will be getting an entirely new type of gear slot called “tactical items.” They are “build defining,” and they will alter character abilities and playstyles. Players can acquire them in a several ways, including crafting and player vs. player combat.

“Our philosophy for this expansion is ‘play your way,’” the developer says. “Items have always been an important part of your character’s identity, but for the first time we are offering true depth and choice with exciting new items that let you decide how to play in the upcoming battle.”

Star Wars: The Old Republic first launched in 2011. Onslaught is the seventh expansion.
