Army of the Republic of Vietnam Invades Rising Storm 2: Vietnam

Steam now offers the promised Army of the Republic of Vietnam content as a free update for Rising Storm 2: Vietnam, Tripwire Interactive's military shooter sequel. This post has a changelog for the new version, and this one has videos for the launch, including the launch trailer. Here's some of the announcement:
Tripwire Interactive and developer Antimatter Games continue to expand and improve their award-winning first-person shooter RISING STORM 2: VIETNAM with today’s release of the free Army of the Republic of Vietnam (ARVN) Content Update. As part of its continued commitment to support its active community with regular and significant free updates, today’s ARVN Content Update introduces the Army of the Republic of Vietnam as a playable faction along with new maps, weapons, and more.

Over one million Vietnamese served in the ARVN over the course of the Vietnam War, with over 250,000 lost in action. Largely equipped with older US military equipment and trained by foreign military advisors, ARVN soldiers bore the brunt of frontline fighting throughout the war both prior to the escalation of US military involvement and after the US began reducing its troop presence.

With the release of the ARVN update on May 29, 2018 for RISING STORM 2: VIETNAM players can play as soldiers in the ARVN faction for the first time, as well as enjoy new weapons and five brand-new maps.
