The new Da Krong terrain built by Razorback is at the heart of the Unsung for Arma 3 development. The terrain offers a rolling landscape with a highway, two waterways, two fixed US bases atop of hills and various Vietnamese settlements. The area is dominated by a dense jungle which may hold a surprise or two for the unwary squad exploring it. Buildings used are partially of Unsung 2.6 legacy, partially freshly developed.
Rung Sat special zone is a hot area, in any sense. The Doung island is embedded in the middle of the special zone and hosts a number of smaller islands and waterways between them. Even a short airstrip can be found to the east of the main island. Dense tropical jungle, mangroves and palm trees compose most of the vegetation.
