Heliborne is a multi-player game of helicopter combat in either co-op or PVP modes but a single-player campaign is also available. The developers describe the gameplay as a "simu-lite/arcade hybrid" where players fly one of three helicopter classes - Attack, Air-Assault or Reconnaissance - in four tiers representing the development generations of helicopter design. Players can unlock the next tier of helicopters, offensive and defensive equipment and also skins (paintjobs) for each helicopter in the same manner as games such as World Of Tanks. User Summary
