Revamped gameplay, updated maps, improved helicopter controls - this party's a riot!
Please note that everyone who owns Rising Storm 2: Vietnam will also be able to play the base class (Rifleman) in Green Army Men for free - you don't need to own or download this Upgrade DLC to play.
However, purchasing this upgrade will give you access to the remaining classes within Green Army Men - AND all the revenue generated from the sale of the DLC will be shared with the Green Army Men Team to support their ongoing efforts!
