Tripwire Interactive now offers the Island Assault content pack for Rising Storm, a free update with new content for the multiplayer military shooter. To help get the word out, there is a free weekend underway on Steam along with a sale where Rising Storm is 50% off. This trailer shows off the new content the pack brings, which is described below:

• Multiplayer Campaign Mode is an all new paradigm in multiplayer FPS games – more than just a game type, it ties the game types and individual matches together into a campaign that can keep you occupied for hours. This gives the multiplayer game more depth than ever before, as individual matches now matter for the overall victory or loss in the MP campaign. Both sides battle it out to control territories on a large scale battle map, voting on which territories to attack, whether to attempt to take more territory, or to defend and try to grind down the enemy's resources. We like to say it is like a “meta-game" of Risk. This features both Stalingrad and Pacific Theater campaigns.
• All new level: Betio. The tiny island of Betio was the scene of the heaviest fighting during the Battle of Tarawa in November 1943, the first major US amphibious offensive of the Pacific Theater. The map here recreates the push of the US 2nd Marine Division across the devastated island against their counterparts in the 6th Special Naval Landing Force (the Japanese 'Marines') as the US forces attempt to disable key tactical objectives such as naval guns and transmitter stations. The map favors desperate pitched defenses and assaults at all costs.
• Two new weapons, one for Rising Storm and one for Red Orchestra 2. Red Orchestra 2 gets the PPS-42 submachine gun. Born out of desperation during the siege of Leningrad, the PPS-42 provides the Russians with a powerful, lightweight SMG option. For Rising Storm, the Japanese get the Type 97 sniper rifle. More accurate than the existing Type 99 sniper rifle, this weapon gives the Japanese another way to reach out and touch their enemies.
• Classic Mode Refinements. While Rising Storm and Red Orchestra 2 are considered by many to be one of the most hardcore shooters out there, the hardcore among the fan base have been clamoring for something even more extreme and authentic. The fans have asked and we've answered with further refinements to Classic Mode (the most hardcore gameplay mode in RS/RO2). We've made player movement changes, as well as aiming and recoil changes to make it more difficult to keep your aim on enemies resulting in longer and more intense firefights.
