A post on the Red Orchestra blog announces Rising Storm as the first expansion pack for Red Orchestra 2. It'll ferry Red Orchestra 2's bloody, muddy realism out to the sunny, sandy beaches of the Pacific theatre, where American forces will battle the Japanese army on famous battlefields like Tarawa, Kwajalein, Saipan, Iwo Jima and Peleliu.
The expansion is a total conversion created with help from Red Orchestra's active modding community. Tripwire recruited a "hit-list" of modders who had worked with Tripwire before, and asked them to help produce the expansion.
"As Red Orchestra: Ostfront had such an avid modding community, producing some pretty good content, it made sense for the Tripwire team, the core of whom were ex-modders themselves, to offer this opportunity to a team of modders," Rising Storm producer Tony Gillham tells Gamespy .
The US and Japanese factions will be asymmetrically equipped. Gilham tells Gamespy that balancing the well-equipped US forces against a Japanese army that hardly used automatic weapons at the time is the biggest design challenge for the team at the moment, but they're hoping that carefully constructed maps can help to even out each battle. The expansion's due to arrive at an unspecified point this year, and IGN have the announcement trailer, which you can see below.
