ALPHA SOFTWARE: Project Rotorline is actively being developed. Missions, balance, performance, controls, and presentation may change.
Project Rotorline is a helicopter-focused Unreal Engine 5.8 action game created by Keith League (Rooster). Its current Alpha campaign spans 25 missions across rescue, reconnaissance, escort, strike, extraction, heavy-lift, and final evacuation operations.

Run the setup application and select Install and Play. The installer downloads the current Alpha, installs the required Microsoft runtimes, creates a desktop shortcut, and launches the game.
Windows may display a security warning because this Alpha installer is not code-signed.
This repository contains a source snapshot of Project Rotorline.
Licensed binary assets are intentionally excluded, so a fresh clone is not a build-complete Unreal project and is not presented as a playable distribution.

Content/Data
Project Rotorline remains in Alpha. The current campaign reaches Mission 25. Testing, optimization, content polish, accessibility, and hardware coverage are ongoing.
Performance targets and minimum requirements are provisional. Testing has included an RTX 2060-class system at approximately 30 FPS under reduced settings, but results vary by mission, resolution, and hardware.
Project Rotorline supports keyboard, gamepad, and flight-control hardware. Use the in-game Flight Controls menu for device selection, axis calibration, and bindings; exact mappings may differ between devices and player profiles.
