Helicopter

Becomes weak after losing 500 health. 30% Bullet Damage

Attacks more aggressively after weakening
After being weakened, takes full bullet dmg Will target players with LMG or RPG-7 first over other players (And of course people with the highest scores and anyone shooting at it.) Helicopters enter the map from one of several directions and travel between pre-determined points (with a bit of randomness) around the map until it loops back to the beginning. The loop lasts at least one minute, give or take a while depending on the map. After losing about half of its health, the helicopter engages "Evasive Maneuvers" state and is "weakened" against bullets, which now do full damage. It will randomize its path for a moment, then travel from point to point more quickly and spend less time hovering in place.
