Our 2013 multiplayer game of the year

just got a little better. Tripwire Interactive has been great about adding content to

Rising Storm

for free after release, and today it did again with the Armored Assault: Free Content Pack. To celebrate, the game is only $5 until September 26.

The Armored Assault updated applies to both Rising Storm and Red Orchestra 2. It adds a new weapon, the German MG 42 light machine gun, which is a veteran unlock for the Axis MG class, and two new tanks. The first is the Russian T-70, a small, fast tank that can carry two players and a 45mm cannon. The second is the German Panzer III, which is a smaller version of the Panzer IV, armed with a 50mm cannon.

There also two new maps: the jungle-themed Kobura where the Japanese team attacks US defensive positions, and Tula Outskirts, a remake of a map from the original Red Orchestra. The Arad 2 map has also been updated to accommodate the new vehicles.

If you don't already own Rising Storm, it's on sale this week for $5, or 75% off its normal price. If the trailer above didn't convince you that you should have bought it already,
