Tripwire Interactive has released a full software development kit to assist players in creating mods for their popular World War II shooter, Red Orchestra 2: Heroes of Stalingrad.
The mod SDK has been available in lesser form for a while now, but today Tripwire has released the full set of tools for everyone who purchased a copy of the game. Already, in fact, there are at least three full conversions in the works - one of which is featured above. In Country: Vietnam is a Red Orchestra 2 modification that takes the game's tactical realism and moves it forward a couple decades into the Vietnam War.
