Its first attack, Ground Support, is a strafe-run like attack that hits enemies three times. Compared to its imperial rival, it has a shorter reload time.
The second attack, Machine Gun, is an anti-air attack much like the anti-air attack of the UH-1B SkyRaptor.
The third attack, Scattershot, is a shotgun attack that deals heavy damage to the targeted area along with greatly reduced damaged to the adjacent areas. The high damage makes it effective against armored targets, even though it has only 30% armor piercing. This attack is the Chunook's mainstay.
The propellor blades stop moving when the shotgun attack is used, this is not true for the enemy version.
The Chunook's name seems to have come from the military Chinook, however, unlike the real life one, this one does not have dual rotor blades.
The main idea for the Chunook is from a 1981 movie called "Road Warrior " and the main person is a hero named Mad Max who also wields a handheld shotgun and rides a Chunook.
