The game is divided into "Generations," allowing you to fly iconic birds like the UH-1 Huey in Vietnam-era maps or advanced gunships like the Ka-52 Alligator in modern scenarios.
The "Collection" version includes a deep tech tree where you earn experience to unlock newer models and weapon configurations, such as Anti-Tank Guided Missiles (ATGM) or specialized air-to-air payloads. You can also customize your pilot avatar with different flight helmets and skins.
