The Official EA Star Wars website announces plans to bring offline mode online next week in Star Wars Battlefront, saying we will be able to witness the firepower of a fully armed and operational battle station in September with the release of a Death Star expansion (thanks nin). Here's the plan (many Bothans died to bring us this information):

To get right to the point, we’ve been listening to your feedback and your desire for more offline modes. Today we’re excited to officially announce a new mode, Skirmish, for all Star Wars Battlefront players.

The new mode will be available starting July 20 and offers players the option to play offline against bots in a solo mission or with a friend using co-op split screen. (Console only) Skirmish can be played on a difficulty level of your choosing and across two modes, Walker Assault and Fighter Squadron. With multiple locations that span the galaxy, from the frozen planet of Hoth to the lava encrusted planet of Sullust, we hope Skirmish brings players a new way to enjoy Star Wars Battlefront.
If an offline mode isn’t for you, we have more free* in-game events planned for the summer. Look forward to more Hutt Contracts for new weapons, log-in reward opportunities, and open trials to experience Bespin.

Then in September, Season Pass holders will receive our third digital expansion pack, Star Wars™ Battlefront™ Death Star. More new maps – on ground and in space – new weapons and Star Cards and two new heroes including one larger-than-life character we know you've been patiently waiting for. Not a Season Pass holder? Don’t worry, the expansion pack is available for separate purchase.
