Earthrise, the indie sci-fi sandbox from Masthead Studios. A rather large patch has made its way to the live servers, and the changes are so numerous that Masthead's press release labels the update as Earthrise's first expansion.
The big kahuna in terms of new content is the Territorial Wars functionality, and the patch notes mention new zones with bases ripe for the capturing as well as the ability for guilds to construct various economic and military structures. Speaking of guilds, leaders can now make use of a new ranking and permission system, and Earthrise now sports both friend and ignore lists in addition to improved client performance.
The patch also brings a laundry list of weapon effect changes, combat re-balancing, and bug fixes, all of which are viewable via the patch notes on the official Earthrise forums. If all that's not enough to whet your appetite, consider that Masthead has reduced the initial client cost by 40% as well as gifted all previous account holders with 10 days of free play.
