It's the last piece of The East Wind campaign, adding to episodes Survive and Adapt. It's the opportunity to experience "combat on a larger scale" using all skills.
They wanted "tactical freedom" at the heart of episode 3, "together with big, combined arms engagements" as the campaign around Ben Kerry draws to a conclusion.
Three new vehicles are also packaged in Win: the single-seat A-164 Wipeout aircraft, the close-air support of the To-199 Neophron, and a 6x6 mine resistant transport truck the Tempest. There's also a 'Fixed-Wing' Showcase mission added, introducing the new aircraft. The 270 km² Altis terrain has also been tweaked with new landmarks.
The third and final Arma 3 episode 'Win' releases March 20th.
