Fans of Unreal Engine titles are already well acquainted with how terrible it is to update those games. We're talking about multiple GB updates even when something super minor is changed. It's the nature of the engine. That is, until now.

With today's update to Red Orchestra 2, Tripwire has incorporated the "Brewing System" into the game. That means that after today's massive 8.5GB update, future updates should be significantly smaller in size, say only a few hundred MB. In addition to this very welcome addition, the update includes a new gametype, new transports, fixes, a new map, and more.

Merrill's Marauders, made up of a series of light infantry assault units (lacking heavy weapons), was ordered to take up position at Nhpum Ga and hold it against attacking Japanese forces in April of 1944. Ill equipped for this holding action, the Marauders were put under siege and often time surrounded by the Japanese.

Faced with poor health conditions and limited supplies, the Marauders managed to hold. At the end of the battle, 400 enemy were confirmed dead with 57 dead marauders and hundreds more wounded or incapacitated.
