The next big Rising Storm 2: Vietnam free update was announced at Tripwire's PAX West panel today, and we have exclusive screenshots (below) and a video (above) for you. The working title is 'ANZAC Update,' and it's a big one.

ANZAC adds a new faction, the Australia and New Zealand Army Corps (hence the update's temporary name), and with it a pile of new weapons, two new maps, and one new chopper.
