Copter is a unit chassis type in Sid Meier's Alpha Centauri.
Game info[]
Copters, with their maneuverability and ability to land temporarily in rough terrain, make formidable combat units. Copters should return to a friendly base or airbase at the end of every turn for refueling. If it is unable to do so and must land temporarily in the field, it incurs 30% damage.
The 'Copter chassis is available upon the discovery of Mind-Machine Interface technology.
Units with this chassis are atmospheric corps units that can attack multiple times per turn, but must return to a base or airbase within the same turn or it will crash-land and suffer damage equal to 30% of its maximum structural integrity in the process. A 'copter which has landed in such a fashion can be attacked by both air and ground units.
A 'copter with the Air Superiority ability may be known as a "lifter".
